OCP
OCP - Open Controller Platform is software platform that makes it easy to build a cross-compilation toolchain with compiler, assembler, emulator and programming tools for embedded systems. This project is inspired by the buildroot project, but unlike buildroot, the target here is micro-controllers like Microchip PIC and Atmel AVR.
Currently, OCP is able to build software for Intel 8051, Maxim 80DS390, Zilog Z80, Motorola 68HC08, Microchip PIC16 and PIC18.
OCP is hosted at sourceforget.net, where source code, snapshots and like are available.
