Rookie

the Eval board looks interesting

Rookie

I look forward for the second day

Rookie

nice job on the first day

Rookie

Excelent presentation, I think to migrate to STM!

Rookie

Jacob, thanks for an informative seminar, hope to receive the eval board.

Rookie

Thanks you Jacob, hope I have the chance to get the evaluation board.

Rookie

Enjoyed both sessions! Thanx for extending your expertise in this area.

Rookie

@theslawek
Thanks for the info on linux/gcc!

Rookie

Hi would this controller be good candidate to be used to read ultrasonic sensor?

 

Rookie

Enjoyed both sessions.  Hope to be able to continue with the STM32F4 evelopment board next week.

Hi all... can I save this presentation?

Rookie

Audio was fine on replay. Thanks!

 

Rookie

Excellent view of MCUs

Rookie

Excellent overview, right level.  Looking forward to next sessions.

Rookie

Is Session 1 achived in a place where I can access it and replay the audio stream?

 

Rookie

Thank you, It's a good overview.

Rookie

Catching up after the day's work!

Rookie

Thanks. A great start.

Rookie

Thanks @exerryan for your answer to my earlier question.

Rookie

Thanks so much Jacob and EETimes U.  I was a little late but I hope I'm still in the first 1,000 to attend this lecture.

Rookie

Simple, yet very enjoyable for beginners!

Thank you Jacob

Thank You, I look forward tothe other sessions.

Rookie

I look forward to the rest of the series!.

Good overview for people new to microcontrollers.

@theslawek - Maybe a late respose, but you are correct: the MCU handles pipelining. The programmer does not explicitly utilize pipelining but can take it into account when coding in Assembly. For example, many MCUs will execute the instruction after a jump instruction because the true/false check for the jump occurs a few stages into the pipeline. A programmer can prevent a wasted instruction by swapping the order of the jump instruction and the one before it.

Rookie

 

hello from Mishawaka

Looking forward to tomorrow.

Rookie

Good introduction to Microcontrollers.  Hopefully you can resolve the broadcast issues by tomorrow.  I had to listen to the downloadable archive.  The bad part is that I am not able to post questions as the presentation goes along.

Rookie

Informative session, thank you!

Rookie

Thank you for the great session

Rookie

@ST_Stuart_McLaren -sure. Thanks for the info!

Rookie

@IKay20 - Session 4 covers the FPU in more detail including running some examples with the FPU on and off

From this intro it sounded like instruction pipelining is done in the MCU core and not something the programmer explicitly utilizes. Am I mistaken?

Rookie

@EETimes - that might be a good topic for someone to cover on the PCB designline at some point. Just an overview how different products are designed from the ground up.. a glimpse into schematic capture, simulation, prototype PCB.. what tools are used, etc. Since SMD devices are all the rage, how ARE different companies doing the development? Do the device guys at "Company X" have PCB Milling machines, pick-and-place and wave-soldering systems just lying around sitting next to the office printer? Or are they spending time in simulators, then sending the designs out to some board house for completion? heh.. I dunno, that might be too basic a question that most readers "in the industry" would know. As a hobbist, I'm probably not in the EETimes target audience. :)

Rookie

I suggest a bit less time on instuction pipelining and a bit more time on the NVIC (and WIC).  The method (and benefits) of nesting interrupts using tail chaining is brilliant and an important selling point for the ARM Cortex-M3.

Rookie

@drw36 and @keyoke

These adapter boards from Schmart boards make it easy to solder the small pitch parts. I've hand soldered 0.4mm pitch board to board connectors with one of their adapters.

http://www.schmartboard.com/index.asp?page=products_qfp

Rookie

Page numbers missing from slides 8 and 9.

Rookie

@drw36 - yeah, I saw that. I'm amazed at how small things are getting. SMD is great, but developing this stuff as a hobbist is a major pain. It's getting to the point where I can't even etch boards @ home any more because I cant get the traces small enough with good enough quality to make the board viable! How do the "professionals" do it I wonder? I wonder how engineers are designing and building things like cell phones and MP3 players, TVs, etc; since they aren't building these circuits on a breadboard anymore.. they have to be prototyping these out somehow, though probably not physically anymore.. Allego/orCad, Altium, CadSTAR and the like are good - but is the simulation software really that good? 

Rookie

How long with this live chat be available today and what time will it be open tomorrow? any idea?

Rookie

@keyoke - datasheet shows the STM32F429 part is available in a QFP package. For breadboarding you'd need to use a DIP adapter pcb and careful soldering :) . For the hobbyist, or even just us older folks, things are getting difficult.

Rookie

@seancar
@mike.haley

Email sent.

Rookie

@DavidWR  --  sure.Thanks!

Rookie

@IKay20 -- check tomorrows slides for some hints.

There are benchmarks. The difference with FPU is dramatic.

As I recall you must tell the compilers to use it on all M4 units.

Rookie

Very good class, Thanks ,

 

Rookie

WayneDuq put up links to info.

Check tomorrows slides for links to Class material.

Sorry -- I know I cheated.

 

Rookie

How many cycles does the M4's FPU would take for a floating point operation? DOes it perform the floating point operations in the FPU by default or does it need speacial instructions ? If it need speacial intstructions how many cycles would a floating point multiplication would take when not using FPU?

 

Rookie

@theslawek I would like the guide too.  frommike2you@gmail.com  Thanks!

Rookie

Good session -- hope I get a board to follow along -- if not will struggle with original Discovery F4 with Embest Add-on modules...

Rookie

theslawek - I would be interested in your config guide. sean.cardosa@gmail.com. thanks

Rookie

@scott93

You've got mail!

Rookie

EETimes should have BIG RED BUTTONS on the webpage to "TEST AUDIO" "DOWNLOAD SLIDES" so the chat screen doesn't fill up with cries for help

Rookie

Q: "So, when you say Standby Mode: 0.3 uA. Does it includes I/O leakage?"

A:  That would be accruate at room temperature, however leakage is highly temperature dependent, so if your end product needs to live through extended temperature cycling, you'll need to take this into account when it comes to your power budget and battery life.

thank you, good day to all

Rookie

WHAT ABOUT IF THIS WORKSHOPS ARE EXTENDED TO 2HOURS!!!  WITH MORE CONTENT  SINCE LERANING EMBEDED WELL APPLIES TO MANY MCU, THE DIFERENCE IS ON THE REGISTER CONFIGUARTION AND SUPPORTED SOFTARE IN IDE...

Rookie

@DaveWR, WayneDuq:  Thanks for lead on the libraries at the ST website; should have check there myself.

Rookie

theslawek - I would be interested in your config guide obnoxium@sbcglobal.net

thanks

Rookie

keyoke - the STM32 needs minimal external components as most functions are integrated (internal clocks, supervisor fuctions etc) - best is to look at the datasheet.

there are also a wide range of package types

how do we know if we were in the 1000 to get the kit?

 

Rookie

q: "I mean linux as develoment environment with IDE etc, not running it on mcu."

A: It is possible to run Linux as your OS, but I have only heard rumor of using an IDE for ARM Cortex Mx development.  Unfortunately, I cannot point you to an actual IDE title.

theslawek - I would be interested in your config guide. joep.research at gmail.

Rookie

EB2: What about us? :) STMicroelectronics.

 

Rookie

Yes, horsepower.  The ADCs are barely fast enough to get the intensity signal. Not nearly fast enough for the phase based color portion of the signal in analog video.

Rookie

So the discovery kits are a great way to playing around/introduction to the STM32 line. What's the typical BOM look like for a product using these from scratch? I'm pulling datasheets and looking for reference designs now, and they look comparable to AVR in that aspect (Crystal, power regulation, and MCU). From the hobbist perspective, how hard are these to work with? I'm not going to need to deal with BGA or LFN, or 4+ layer boards am I ?

Rookie

Thanks Jacob & Digi-Key - until tomorrow

Rookie

e7 - yes the STM32F429 has a camera interface. You can get detail from the datasheet/reference manual

Check the ST site for board support packages everyone.

Rookie

More details on the STM F4-29I can be found at:

Rookie

10 nA is just 0.01uA unceranty which is more than the measurind DVM used to get taht data average...don't get hung up

Rookie

e7 - you lookng for a vidoe processor? You may need some pretty heavy duty I/O horsepower.

 

Rookie

thank you for a good info

 

Rookie

@GRB1: I just don't remember.... I have STM32F4 -- earlier version with EMBEST Add-Ons. I probably donloaded the package from there and the ST site.

I do not recall thinking very hard... :-) CooCox did make it easy -- I was suspicious at first. Never hear of them.

I do use IAR and TI CCS and CooCox and have compiled under cygwinf and MGwhateveer.

Rookie

Thanks again theslawek, you've made my day

Rookie

Analog Video is only possible with B&W

Rookie

A lot of mixed information in the links I posted. I've made a configuration guide for myself, if someone is insterested send me a message for developing for ST micro's with ST libraries on GNU/LINUX.

Rookie

I've used Code:Blocks IDE on both Windows and Linux for Atmel dev, not sure if there is ARM support?

Rookie

ArnaF2727: Digi-Key should be getting more stock in. Pls check back with them later this week.

Rookie

In STM32F4 - any possibility to read video input signal?

In slide 9 you say that:

I/O leakage : 10nA

So, when you say Standby Mode: 0.3 uA. Does it includes I/O leakage?

Rookie

Thanks, theslawek & mattfolsom
I've had a lot of trouble with Eclipse in Linux, and have been forced to use Windows  :(

Rookie

Yes Jacob I appreciate the differences. Been doing embedded on MPUs adn MCUs for 25+ years.

It is amazing how far we've come.

Rookie

I just looked at Digikey and the part is not available until January....for the other American supplier they are out of stock. If I am not one of the 1st 1000 am I just out of luck?

 

Rookie

@DaveWR:  I probably should have also asked where you pulled the libraries from, another IDE like IAR or Keil?  I'll give it a try anyway.  Thanks.

Rookie

Anton_B - max DMA on STM32F429 is 90MHz

This is a great series Thanks!

Freelancer

Coocox is great.  It is just a Eclipse based IDE.  But very easy to setup. Also easy to add new controllers not included.

Rookie

Leviton Dave, it is ........ just think of all the things you could do with all that power! (computational that is)

Blogger

Thank you, Jacob for this interesting seminar.

Yeah. I see the "traditional" difference being that of having the memory embedded in the chip. Though with DMA, and using it to interface with external SRAM, that line is blurred indeed. It's really amazing how far technology has come in such a short time with this kind of thing. 

Rookie

The M4 is more powerful than my first computer and many of the computers on the space shuttle. :)

Rookie

@GRB1: I don't recall how to hook in Lins exactky -- it was not difficult. Try it out -- see how you do with CooCox

http://www.coocox.org/index.html

 

Rookie

ST_Jeff_Blauser, I mean linux as develoment environment with IDE etc, not running it on mcu.

Rookie

keyoke, an MCU typically has program memory and peripherals built in so that it is essentially a self contained device. A CPU needs external device support. As a result, an MCU typically is resource constrained.

Staff

miha_alex M4 adds DSP instructions as well as FPU

hah. nevermind. I should google my questions before I ask them. :)

 

Rookie

Keyoke, they very much are blurring the line.  What is considered high end mcu like the Cortex-M4 I used to consider to be a CPU.  However, CPU's like desktops still use distributed RAM, external drives, everything isn't integrated into a single package.  I consider an MCU to be resource constrained!

Blogger

@DavidWR:  What did you have to do to include the ST libraries in the CooCox IDE?

Rookie

I am looking forward to learning more about the ARM Mcu's !!!

Rookie

M4 has the DSP instructions, independent of an FPU

 

Manager

e7 - the STM32F429 has an LCD controller with support up to SVGA resolutions. There will be a hands-on class with this in session 5

@scott93

TrueStudio is practically Eclipse IIRC and you can use their startup scripts.

I develop on Linux and everything works fine (for free!)

To use ST-Link2 on linux, see this: https://github.com/texane/stlink

Rookie

Thanks Jacob. Great intro.

out of curoisity - what's the difference between a MCU and a CPU ? Devices like the STM32 (and other ARM based devices), with DMA and other features are kind of blurring the lines of traditional MCU/CPU (and even begining to enroach a bit on DSPs) aren't they? 

Rookie

We'll look at the ecosystem as well in the next couple of days.

Blogger

FPU is the only differnce between M3 and M4?

 

Rookie

Oops, Em:Blocks is windows, not linux. Sorry

Rookie

I would love to have one board 

 

Rookie

Jacob, Thanks. a want to ask: what is maximum DMA frequency?

Rookie

This course will focus mostly on ARM Cortex family with the STM32F4 as the development kit for the labs.

Blogger

Thanks for the overview!  Am looking forward to the remaining sessions :)

Rookie

Q: Is development possible on open source systems like linux / ubuntu?"  I use eclipse and GCC on Linux.

A: it is possible with uC/Linux, not Ubuntu.  Please keep in mind this is a microcontroller and not a microprocessor.

ST has software tools via 3rd party. If you you are referring to compilers, we have several options like IAR, Keil, Atollic ...etc.Our libraries are written and support IAR with lots of examples.

Sure.  Later in the course we will be working through a number of simple application projects that should help get you up and running.  

Blogger

For those who want to try Open Source on Windows with ARM EABI Compiler   

http://www.coocox.org/index.html

I have it installed it does work with STM -- it will require some tweaking for this Board/Micro

Rookie

ST firmware shows IAR, MDK and True Studio, all for Windows
For linux, there's EmBlocks.

Makefiles for Eclipse would be nice to have in the CMSIS library. Please, better Linux support!

Rookie

Jacob, Will you be talking about various uCs tomorrow (PIC,Atmel,TI / 8-,16-,32-bit) or will we be looking at mainly ARM based devices?

My thanks to ST,and eeTimes and to you Jacob for this opportunity.

Good Show !!

Rookie

Thank you very much, Jacob! I will follow other sessions as well. Would you please suggest some intresting application we can try?

Rookie

Thanks Jacob.  I initaially had trouble recieving the auto and I hdid a computer reboot.  Missed some of the intro during the reboot, but I will listen again using the archived autio file.  All should go better tomarrow, I hope.

 

Rookie

Oops -- 47 on order.

Manager

polonia - I would suggest looking at an MCU familiy which is scalable with pin and software compatibility across the family. That way you can move up and down the family depending on performance/memory requirements

Q: Can you suggest reference books you have found helpfu?

A: There is ALOT of information on www.arm.com on the generic cores, and you'll want to search on the Cortex M0, M3, M4.  In addition, you may want to consider "The Definitive Guide to the ARM Cortex-M3" by Joseph Yiu.  He has also written one for the Cortex M4.

ST has a demo with STM32L1 that supports energy harvesting. Any low power MCU with I2C can support dual interfaced with energy harvesting

Linktech, later lessons we won't focus in on IoT or internet connectivity in this course but it is an active research area for me (along with low power design techniques)

Rookie

Is development possible on open source systems like linux / ubuntu?

Rookie

Leviton, I would look at sleep modes although the important thing is how much work needs to be done!  You want to be able to put the mcu in  low power mode and keep it there as long as possible.  We'll talk more about mcu selection tomorrow.

Blogger

Good overview. Will try my best to attend the whole series.

Rookie

i think

LVD = low voltage dropout 

Rookie

Jacob, Thanks. Will you be speaking to "A microcontroller is a good choice for an IoT device.  There are a lot of easy ways to add internet functionality to a microcontroller" and some of the ways to do this in the later sessions ?

 

Rookie

What type of lcd ctrl can we find in STM32 F4?

 

Rookie

Any discussion on software tools?

I assumed Harvard because it's so common, but it's not clear from your slides.

Rookie

Allen yes, archive will always be available

Rookie

@Qwerty - Newnes (I think) publishes at least two ARM-only books.

 

Manager

OK, bye guys.  See you tomorrow!

Rookie

?? Hi Jacob, You mentioned microcontrollers being used in in Switched Mode Power Supplies.  How often have you seen these used instead of a 555 timer?  thanks

Can we download the audio after the class is finished - a lot of good reference material here.

 

Rookie

Thanks, nice overview

 

Rookie

Jacob,

On the Low Power Operation slide, the VLPR definition states that LVD is off.  What is LVD?

Rookie

M4s are Harvard

 

Manager

Thanks.

 

I have a question. What makes more sense: design with the simplest forma factor and mcontroller complexity or buy the best equipped ultra performant unit even though it might be an overkill?

 

Rookie

Hi, I am from India. Its actually 11:10 PM here but still interested in listening to ur lecture.

Thanks Jacob. It was a helpfull presentation. Looking forward for your next lecture.

Thanks, Jacob, ST, and EETimes. Please increase make the audio volume next time.

Rookie

On the USB slide, does the proc run the pins directly or does it need an external USB controller (I am interested in a "hub" mode where, in addition to just being a hub, the proc can also participate as a host or a slave)

Rookie

To be qualified to receive a board, you must participate in both session 1 and 2 (today and tomorrow), have a US or Canada mailing address AND be among the first 1000 registered!

Rookie

See you tomorrow. Please speak up or adjust the audio. Looking forward to hands on presentations

Thanks for putting this on Jacob. It's appreciated!

Rookie

Q: capacitive touch is not touch screen readout for TFT ?

A: It is possible to enable and operate capacitive touch on a TFT LCD depending on the nature of the physical touch construction.  For instance, if you have ITO as discrete locations on the screen, it is possible to decern which location is being touched.  This would not necessarily include a multi-touch experience unless the designer wants to extend the capabilities beyond today's firmware release.  Most TFT, ITO screens we see already come with an attached device to handle capacitive touch down to the pixel level.

Can you please re-explain the piplining process

Rookie

Thanks Jacob.  Looking forward to the rest!

That is good point - everyone should check that their mailing address is correct

Robert from Saint-Eustache,

Unable to ear the presentation, will try from home tonight.

Rookie

Can the board be sent to a PO Box address which is in my contact ID or how can I specify a shipping address?

Rookie

the same for me as other attendee from poland !!

Rookie

next session starts the same time ?

No audio for me but it is because my company is filtering it, poo.

Rookie

@bartholemew - go to 'edit profile' and you'll see full info

Rookie

Profile (top of page) -> Profile Update link (on the right)

Rookie

how do i review the mailing address in my ee times profile to confirm the board will be sent to the right address?  i don't see the info under my profile.

Rookie

DMA to GPIO is possible.  The GPIO register would be classified as a 'memory' location rather than a 'peripheral' resource. Then the contents can be connected to either another memory or peripheral location. There is a 'bit-banding' feature set available as well which may fit better in certain applications.

Hi from Poland, for me also audio stops every 3-5 seconds and stream must be restarted

DMA can reach all the peripherals and memory as well as the Cortex Core.  It is best to consult the reference manual for the granularity of exactly how to connect each DMA channel to each peripheral/memory.

Can the DMA access GPIO?

Rookie

AUDIO BECOME MUCH STABLE FROM SOUTHERN CALIFORNIA ---BUT I FELL SHOULD USE DIFERENT STREAMING ... THERE ARE SO MANY ...

Rookie
I got audio on iPad
Rookie

It looks like the DMA can access ALL peripherals. Is this the case?

Rookie

kvuk1v : audio is fine

Rookie

Audio rosk solid for me.

Rookie

I hear nothing or the presentation is over? Ottawa, Ontario

Rookie

No audio problems here.

 

Rookie

For Quadrature Encoder operation that would include a zero position (tag), a separate GPIO set as a interrupt or as a Timer Input can serve this purpose.

The audio has been rock solid here as well.

Rookie

I am not hearing the audio.

 

Rookie

The sound is very good for me and I am lestening using 3G of my phone. 

Rookie

@SS99 - Same here. No audio issues at all.

Rookie

To Mark Hilig:

Is the 50us standby-to-active time due to the pipelined architecture?

From standby on the STM32, you have also to consider internal regualtor warm-up and clock settling. Pipelining time would be minimal.

Thanks,

 

No, we are about half way

Rookie

timers can not read in HW the "zero" tag, only PHA & PHB. You have to handle zero tag only by ISR.

Rookie

I don't hear any fading out at all... I am thinking the problem is not at the speaker's end but at the listener's...?

 

Rookie

Audio is not fading, The live feed keeps stopping. Then we have to continuously restart the feed.

 

Rookie

carlutina could you give more detail on your question on quadrature encoder

 

Audio is good for me...

audio is intermittent

Rookie

Audio is good for me

 

Rookie

Is the 50us standby-to-active time due to the pipelined architecture?

Rookie

Audio is fading again

Rookie

quadrature encoder has not zero tag readout capability!

Rookie

capacitive touch is not touch screen readout for TFT ?

 

Rookie

Got the sound with Google Chrome.

 

 

Rookie

'Princeton' and 'Von Neuman' architectures are the same thing?

Rookie

One thing that I found works most of the time for the audio stream with IE is to press play for the intro then press play again then press pause for 3-5 seconds to let the buffer fill a little and then press play again. Most of the time this allows me to listen without interuption for the rest of the lecture.

Rookie

I would think you could try chrome but make sure you updated chrome first... and check for plugins/apps

Rookie

Peripherals please. There are no eels in peripherals. #just_saying

Rookie

I am getting audio thru Chrome.

Rookie

It's not my network filtering as I just tried using a completely different network without filtering.  You need to use a better streaming company.  Try using youtube or livestream or ustream.

Rookie

Not getting audio either.

Rookie

jm589, can you try other browsers?  firefox and chrome seem to work best. 

Rookie

Audio does work...even i downlaod the latest player.... they should use a diferent audio streaming

 

Rookie

I tried IE and Chrome and the player doesn't deploy on either; it must be my company blocking it. I will get the archived lecture at home.

Rookie

you can download from the link above this chat

Rookie

I got the audio stream to work after trying three times.

Rookie

this is hopeless. I tried updating the flash player. I had this problem with the EE times classes last year. Does anyone there monitor these chats? I would think they would have fixed the problem since then.

Rookie

I've try IE and Chrome. Still no sound and the player is not working

 

Rookie

chrome is excellent, good audio, no problems here.

Rookie

are there presentation

to check where are we in the presentation i just got here

 

Rookie

Rookie

What is going with this stream?????

Rookie
If you get about 1 second of sound then nothing your company is cutting the audio stream.
Rookie

Staff

I will try Chrome, if the player still doesn't run, I will have to get the archived lecture tonight at home.

Rookie

Rookie

Greetings, just got out of a meeting, audio OK

Rookie

Had audio drop out using IE. Switched to Chrome and is working fine :)

Rookie

Rookie

Folks that are having trouble with live audio will  be able to listen to the archive about an hour after the live portion

Rookie

check firewall settings or popup blocker

Rookie

Audio is back, now.

Rookie

Rookie

refresh or log out and relogin

Rookie

Good Morning

Rookie

Rookie

Rookie

Rookie

We aren't permitted to use Adobe Flash Player. Guess I am out

 

Rookie

If you are using IE and get no audio switch to use Chrome, log in again and you should see the Flash Player displayed, just click PLAY.

Rookie

Theo from Toronto. No audio is being received. I am working on it.

Rookie

Audio has been lost.

Rookie

As colheckman stated, some companies block live audio streams. You'll need to catch the archive to listen to the session.

Rookie

Rookie

Hi from MN. The player doesn't load

Rookie

The sound is low for me :(

 

Rookie

 some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser.   Also, Firefox and Chrome seemed to be the best browser for listening.

Popular course I guess.

Hello Good morning

Rookie

If you are outside of the US/Canada you can still purchase a board from your local ST distributor for use in the hands-on classes. The orderable part number for the board is STM32F429I-DISCO.

Some options to purchase are listed at the bottom of this page http://www.st.com/web/catalog/tools/FM116/SC959/SS1532/PF259090

 

I hail from Michigan, which makes me eligible...I think:  most folks on the Left or Right coasts tend to believe we Midwesterners are from a foreign land!

Rookie

Hi, I've already enrolled in the course, and looking forward to attending it!
Are the sessions going to be self contained, assuming we don't have the STM32F429 Discovery board (nor there's a chance of winning one outside US/Canada)

Rookie

Ah, found it. You must attend (live or archive) both sessions by 5pm Pacific time Dec 3 to qualify for a board.

Staff

@pumaspread, these presentations will be archived pretty much immediately following their conclusion. So, you can hear the archive anytime after the live session is over. Presentation materials should be downloadable before the presentation starts (and thereafter, of course).

I'm told that even if you cannot make the live session, you can still get credit for attending (and qualify for a board) if you view the archive promptly. Once the shipping list gets generated, though, that opportunity closes. Not certain of the timing, so if you cannot make the live session view the archive as soon as possible thereafter. Oh, and you must attend both of the first two sessions to be able to get a board for the remaining three.

Staff

Unfortunately, if you read the fine print, the boards are only available to those in the US and Canada. The reason for this is the complexity of shipping overseas. Things like customs, duties, shipping cost, and time to receive make it impractical to promise units elsewhere.

Staff

Hi, wonderful idea this series! I'm sorry I'm not from US, Canada, I'm from Italy ,I hope to have a development board for the labs if I'm in the first 1000 if possible

Rookie

i am from india, and i am also interested in this free discovery board.

 

Rookie

Quite excited. I'm very much hoping to be one of the fist 1,000, if not is it possible to purchase the STM32F429 Discovery board through EETimes? Or is it best to purchase it through AVNet or someplace similar? I'd rather give EETimes the business if possible.

Rookie

The 32F429I-DISCO is the one!  If you are one of the first 1000 to attend the sessions you will get one for free!  Just FYI

Blogger

Yes if you have a board you will be able to do the labs from the hands-on portion!  Also the first 1000 people who attend the sessions will get a development board for the labs!

Blogger

Are there any place I can watch previous class vedio?

Rookie

What SoC boards should a person buy to help them with this course?  There are only 5 32F429I-DISCO in the USA at the time I am writing this.  (At avnetexpress) 12:30 PST 2013, 11/21

Rookie

Looking forward to this series!

The future of professional training is here. Holodecks are next.

Rookie

Would you kindly include a walkthrough of the steps to initialize and set up the DCMI program, DMA based, and identify where the captured image resides in memory. I have combed the documrntation and blogs from STM to Italy, and cannot find out how that DMA process is setup and executes.

Extremely frustrated with thw pitiful and convoluted documentation for this well designed but useless, undocumented feature.

Rookie

This is a great opportunity.  Thank you for organizing thei event.

Rookie

I have an STM32F4 discovery board. Can I do the hands on sessions using this board?

 

Thanks.
