Aubrey....Microchip have jacked up their IDE recently, I've never done much C so I couldn;t say how good (or bad) it is, but I've heard from folks that use it that it is not too bad

Would you be working in assembler then?  Would this (RISC) matter much if you were working in C?

I have only worked in assembler with the PICs. I am sure a C compiler would hide the issues if you could get iot to compile for on of the really small PICs that I was looking at. The problem with a bias is that it is preconcieved and brealimnk the bias is much harder once it is established.

Aubrey... "I started off by looking at Microchip, but ...I am afraid I never felt at home with the paucity of instructions (it being a RISC device)"

Would you be working in assembler then?  Would this (RISC) matter much if you were working in C?

That said, they Cypress devices do look tasty, and free dev tools are great.

By an even stranger quirk of fate, when I went to tthe post office this morning to pick up the mail from my PO Box there was a large envelope with a return address from Arrow. When I opened it up, there was one of the $4 PSoC 4 Prototyping kits. The mystery is why they sent it to me and why it got sent to my PO Box instead of my work address. Not that I'm going to complain mind you.

So now that I've been given both the Prototyping kit and the Pioneer kit, I guess I really need to do something with them...

But not until after Field Day (only 3 more days)....

Hi Aubrey.

It's often be said of me that when tasked to buy a half dozen eggs, I return with a box full of (live) chickens and enough hardware to build a chookshed, but I think I will need to abdicate in your favour.

Did you ever get to make a bipolar current output from the PSoC? There's more parts needed than might be expected to be able to do this, I'd probably opt for using an INA , if sufficient headroom were available.

@TonyTib: Come on, Max, you don't need all that complex mega-stuff for the BADASS; all you have to is adopt this for your situation....

Very tasty!!!

Disclainers: although the Papilio Duo has a Mega shield, this still might not be a quick solution since it could be a lot of work to adopt the Wishbone RGB LED controller to the Adafruit serial LEDs.

It is not always bit shifts though, for converting to fixed.  It usually ends up rearranging equations in such a fashion that you do not get any overflows, or get something that you divide by a large number and then get left with something that becomes so small in the middle of the calculation that it induces large errors in the rest of the calculation.

 

I remember where I had a case where I was getting an overflow issue because of a situation where I had forgot to rearrange a multiply so that the equation during the solving process would not overflow.  This was one of those errors that was hard to catch because I just was not even thinking about it, and forgot how large that number could get in calculation.

What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
