Hello, I've tried as: #include and #include "p32xxxx.h" and ..include and ..include "p32xxxx.h" but it doesn't include it.. it includes it only if I use the full path and = use / instead of \ (I'm on a Windows machine), but then it fails on the sub= -includes of course. I've Set The Language Tool Locations, default search path for Assembler Inc= lude, where p32xxxx.h is physically located ( in my system it is C:\Utility= \Coding\MPLab\MPLAB C32 Suite\pic32mx\include ) with and without a trailing= ; but it doesn't include it. :( What can I do more?
