I like to make a guitar pitch shifter for myself and I found this link http://dangerousprototypes.com/forum/viewtopic.php?f=56&t=2003#p19687. I am not familiar what compiler did he used. Could any one help me to make it on hex file his source code, please!

best regards,

I'd take an educated guess at Microchip's C30 compiler. The source references "libpic30.h" at one point. That header file is part of C30, and the C30 compiler is one of the choices to build for a Pic24F.

Anyone know what schematic tools he used to draw this one?

The firmware zip for this pitch shifter is rehosted and attached here

I would also have given the MPLAB C Compiler for PIC24 MCUs and dsPIC DSCs a try http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en010065

I was successfully build (compiled) the given project to  microchip c30 v3v3.31,but when I load the hex file into the programmer pickit2 v2.61,it gave a warning "Some configuration word not in hex file.Ensure default values above are acceptable". Any idea?

At this point I would note take any notice about this. Assuming the code that is posted is working and tested. So default values are probably OK. Give it a try at least.
The topic configuration bits, are to waste to go into in a few few word

Quick look into the main.c, the configuration setting is in there - just make sure to check the "Configuration Bits set in code" in mplab configuration bits setting before you build the project, then it should be fine even the programmer complaint that some of it is not in hex file. Remember also to select correct device, PIC24FJ64GB002 as per schematic.

As stated by the other posters.  This error is probably fine.  Some of the programmers will give you a warning if you do not explicitly define EVERY config bit.  It isn't normally needed as the defaults are typical conservative values.  The ones you need to make sure are set right are the oscillator as these bits don't always have defaults that are correct for your hardware setup.  Most other things should be innocuous.

Really appreciated all the support! Mean while still waiting for the chip I ordered. For sure I'll let you know the out come! Smiley
