PIC32 USB Starter kit II, MPLAB-X and FreeRTOS Demo setup

Trying to run the FreeRTOS demo “PIC32MX\_MPLAB”, presented a significant  
problem for me (newbie to both FreeRTOS and MPLAB X / Harmony). Could not  
get a clean build of the project, due to various errors of missing or  
non-existent include files.

First learned I needed to set “use Legacy libc” (project properties,  
RTOSDemo, XC32 (global options)), which fixed some of the errors, but not  
all.

Still had errors because of missing files from the  
“\pic32mx\include\peripherals” folder. which did not seem to exist. In  
searching for some of these files I found a peripheral folder in “C:\Program  
Files(x86)\Microchip\mpide-0150\hardware\pic32\compiler\pic32-tools\pic32mx  
include”, which I simply copied to “C:\Program Files  
(x86)\Microchip\xc32\v1.40\pic32mx\include” which was missing the  
“peripherals” folder.

Now had clean builds and programmed the starter kit properly.

Do not know if there are differences between the MPIDE and MPLAB-X  
peripherals code, but happy it seems to work for now!

Thought to add this to the support forum, but don’t know how.

Thanks for your post. The head revision in SVN (which will be released  
as FreeRTOS V9) has removed some of the legacy peripheral drivers to  
allow a clean build.

Regards.
