These used the PIC MICRO PASCAL http://pmpcomp.fr/ Welcome to Pic Micro Pascal compiler PMP (Pic Micro Pascal) is a free Pascal cross compiler for PICâ„¢ processors. It is intended to work with the Microchip MPASM/MPLINK suite installed; it has its own IDE and it is a highly optimized compiler. It supports most devices from PIC10 to PIC18. Floating Point is supported (for PIC18 and PIC16 only). The new PIC16 enhanced mid-range processors are also supported. PMP is moving forward with its users (beta testers are welcome): This site is open for comments, discussions, bug reports, new features requests and constructive criticism.
