Re: chipKIT hardware documentation

It has taken me a bit longer than I had originally anticipated to get them done, but I have finished the hardware reference manuals for the Uno32 and the Max32 and they are now posted on the Digilent web site in the support section (bottom of the page) on the product pages for the two boards.

Comments and criticism are welcome. Let me know if you think I've left anything out, and of course let me know if you find errors. (I think that they have been pretty well proof read, but mistakes are always possible).

Also, please note that these are the hardware reference manuals. They don't document the libraries or the boot loader.

There are now Excel spreadsheets giving the pinout tables for the Uno32 and Max32 posted on the Digilent web site as well. These are essentially the tables at the back of the reference manuals in spreadsheet format. I actually copied and pasted from these spread sheets into the manuals to create the tables in the manuals.

How about some help with the following problem:

I ran the "blink" sketch on the chipkit Max32, and got the error message shown below--the sketch failed to compile. It looks like there are software library problems or path problems (this a very long path if it's accurate)--the program apparently couldn't find a particular file. Any thoughts on this?

You should avoid cross posting the same message. It just makes more work for those that read all threads. Also this is off topic here.

Quick question:
If I input a signal of -0.4 V to 3 V on an analog pin is it a long term problem?
The signal comes from the spark plug of a petrol engine. I put it on and measured the first rise over 0.3 V of a spark and then calculated RPM. It worked, but will it damage it if I use it more?

On an oscilloscope the signal seemed not to go down more than 0.4 for about a couple of ms.

Firstly your -0.4 v may be much lower than you can see on a scope, should be easy to protect with a diode to ground.

The original signal was put through a diode bridge and a zenner diode 3.3V.

I solved the problem with the error message indicating that the compile failed. It turns out if the mpide-0022-windows-20110822.zip zip file is unzipped at the C:\mpide-0022-windows-20110822 level, it works properly. I originally unzipped it at a level much farther down the subfolder chain, and this is where it didn't work.

It really would have helped if the documentation would have made this clear.!!!!!

And so, yes, it is appropriate to "cross post" this issue, because it directly relates to the "quality" and "content" of the documentation, OR THE LACK THEREOF!

Hi,
It is little confusing about the connectors such as J6,J9, 8,15. It looks to be indicated on right side of the board(opposite to powersocket ) Iwould suggest to add a picture to indicate the connector pin in the user documentation.
Thanks,
Narayanan
