• MPLAB X Integrated Development Environment (IDE)

  MPLAB X is a free IDE from Microchip for programming their PIC microcontrollers. It runs on Windows, Max OS X, and Linux. MPLAB X comes with the a simulator and the MPASM assembler. It works well with the MPLAB XC Compilers and the PICkit 3.

• MPLAB XC Compilers

  The MPLAB XC Compilers from Microchip are a family of C compilers for PIC MCUs. The compilers are free to use, but paid versions are available that provide better optimizations.

• P-Star Examples

  A collection example code and libraries for the P-Star.

• PICkit 3

  Microchip’s PICkit 3 programmer is a low-cost hardware debugger and programmer for PIC microcontrollers.

• SDCC – Small Device C Compiler

  SDCC is a free and open source compiler that supports many types of microcontrollers, including PIC MCUs that use the PIC18 architecture. The PIC18s are called PIC16 in the SDCC documentation and command-line interface because the instructions are 16 bits wide. As of August 2014, the SDCC manual states that the support for these PIC microcontrollers “is not yet mature and still lacks many features”.

• PICBASIC PRO Compiler 3.0

  A BASIC compiler that targets PIC microcontrollers.

• M-Stack

  M-Stack is an open source USB Stack from Signal 11 Software for Microchip PIC microcontrollers.

• RPicSim

  The RPicSim library provides an interface to the MPLAB X PIC simulator that allows you to write simulator-based automated tests of PIC firmware. RPicSim is written in the Ruby language and runs on JRuby.

• XPRESS-BootLoader

  This bootloader can run on the P-Star 25K50. It acts as a USB mass storage device and allows the P-Star to be programmed by copying a HEX file onto it.
