PIC32 is a family of 32-bit microcontrollers made by Microchip Technology. They contain a MIPS32 core, developed by MIPS Technologies.

PIC32 microcontrollers have been announced in November 2007

Features include

  • Execution speed up to 80 MHz
  • Flash size up to 512 kByte
  • Programs can be executed from RAM
  • Available in different packages, including Dual in-line (DIP)

A PICkit3 is required to program these microcontrollers. Microchip offers an IDE (MPLAB X) which includes a modified GCC compiler (xc32). It is possible to compile programs for PIC32 using the free mips-elf-gcc compiler as well.

PIC32CX register names not in header?

I'm trying to hack away using a PIC32CX BZ2. Since there's no code completion for some weird reason in MPLAB, I'm kinda forced to know the register names, or whatever is set declared in the header files. If they matched with the documentation and I…
