<p><b>New page</b></p><div>This page here is for those who'd like to use Microchip PIC µCs. As usual, linux support is bad, and there are quite a few quirks.<br />
<br />
== IDE ==<br />
=== MPlabX ===<br />
Microchip recently (~2010-10) released a linux version of their new IDE. It can be found at [A]<br />
<br />
There seems to be problems with some versions of ICD2 not being supported by MPlabX, so I will not go further in the details.<br />
<br />
=== Piklab ===<br />
[http://piklab.sf.net Piklab] is an open-source IDE for PIC µCs. It works fairly well, although you MUST create a new project before trying to configure the toolchains (else Piklab will crash).<br />
<br />
Debian-likes have a packages called '''piklab'''<br />
<br />
== Toolchains ==<br />
These basically include compiler, linker, and so on. Which toolchain you chose will basically depend of the µC you chose.<br />
<br />
=== dsPIC ===<br />
Use MPlab's C30 compiler. It can also be found at [A].<br />
<br />
==== Piklab ====<br />
Provided you installed the toolchain in /opt, you must configure as follow:<br />
Executable directory: /opt/microchip/mplabc30/v3.30c/bin/bin/<br />
Header directory: /opt/microchip/mplabc30/v3.30c/support/dsPIC33F/h/<br />
Linker script directory: /opt/microchip/mplabc30/v3.30c/support/dsPIC33F/gld/<br />
Library directory: /opt/microchip/mplabc30/v3.30c/lib/<br />
<br />
Be careful, as device-dependant includes have mixed-case filenames. So:<br />
#include <p33fj128mc804.h><br />
must be replaced with<br />
#include <p33FJ128MC804.h><br />
<br />
If (when) you get an error about missing __reset definition, some additional command line arguments must be specified [http://www.microchip.com/forums/m238536.aspx]. Since I was not able to configure piklab accordingly, I created a bash script to circumvent the problem:<br />
<br />
#!/bin/bash<br />
exec /opt/microchip/mplabc30/v3.30c/bin/bin/pic30-coff-ld.bin --start-group -lpic30 -lc -lm --end-group $@<br />
<br />
of course, you need to<br />
mv pic30-coff-ld{,.bin}<br />
<br />
you might want to do this with pic30-elf-ld as well, and make the scripts executables. With this, I was able to compile a very simple program.<br />
