@perl_geek:

Although the Arduino is aimed at hobbyists, could it have a role in small-volume production as well?

 

I agree with Duane whole-heartedly.  THere are many simpler applications where Arduino could be the "main" processor in a commercial application.  Like (I believe) I said, a standardized interface with a standardized processor and a standardized tool set is a very powerful combination.

Provided the Atmel processor has the "oomph" for the application, and the form-factor fits the need, I see no immediate reason to use anything else.

Of course, there are many applications where the UNO would be nowhere near enough, and too big to boot!  There may always be a case to spend the money and time to design and build a custom application - but where you can, you should always try to standardize your interfaces.

@giogonza:

Hi Tom, excellent work!

Thanks!

I downloaded the files for the LabWindows application but there is only the installer (volume folder and other files inside). I could not find the source code. I'd love to have it because I want to be able to modify your code and control a different shield (relay shield) from LabWindows. Could you please upload the source code or point to a location where it can be dowloaded? Thanks a lot!

 

Sorry 'bout that!

I have uploaded "LabWinSorce.zip" to my site.  It is about 51kB.  It should all be in there.  I am currently using LabWin CVI 2013.

Perl Geek - If the application is right, I think there is a place for the Arduino is small volume production. Since the both the hardware and software is open source, small devices can rather easily be built with an Arduino-compatible core.

Once the design is fully working, the Arduino code can be replaced with more optimized code without any hardware changes.

I've also found it to be a useful prototyping tool in a commercial environment; especially when evaluating new peripherals.

For example, I recently made a design with a Freescale MMA8452Q accelerometer. My design uses a Microchip PIC processor, not an Arduino-compatible chip. There is an Arduino library for the MMA8452, so I built a prototype with an Arduino and get familiar with the code for the chip. Once I knew how to use the accelerometer, I built it into my PIC-based design and got it right up and running. I've done the same with a number of peripheral chips.

If it costs development time, (which is measured in market opportunities lost, as well as direct expenditure), to develop custom boards for projects, there's a case for using more expensive  standard units to speed implementation. (There's also a cost associated with multiple SKUs.)

Hi Tom-ii;

I think it was something I got from reading one of Duanes blogs, but the easy way to keep the sockets or plugs upright when soldering, is to bridge the little beasts with two strips of plugs or sockets going the other way across the board. When soldered just pop off the bridging strips.

The ISP programming input is easy to work with as long as you get a programmer that matches the IDE or compiler you are using.

As a last item be careful with setting clock fuses, you can appear to brick an IC if you get it wrong, however if you have a seperate square wave source try feeding this into the clock inputs and most times you can get it up and running again.

I have found the Dragon programmer to be a boon as it offers high voltage programming for most Atmel chips and this will usually unbrick a dead chip. It also programmes XMega chips as well. All in all the Dragon programmer while not cheap works with care.

Though a $10 usbasp  programmer also serves me well via Arduino IDE.

Having read this blog, I'm starting to think that I should have a play with LabWindows/CVI

 

Max:  For test equipment type GUIs, and easy-to put together code (based on ANSI C), I don't know of anything better.
