Roundhouse is a pair of C based embedded software applications to drive model railroad stepper motor based turntables. It consists of a stepper motor code and controller code connected by an I2C network. Written in C for PIC18/PIC16s processors.
This is a simulation of an open CPU, called 67-80-85. It tries to implement a simple, efficient CPU. It includes the simulator, an assembler, a sample code for a boot loader (ROM), a microkernel prototype and tests. - "The 3-legged shinning steel horse
GenEX automatically generates the SIOC program code for various home built cockpits that use IOCards as their hardware interface system. With GenEx, cockpit builders need not worry about SIOC programming and Project Magenta/FSUIPC offsets anymore.
