This website presents some of the projects I've designed and written software for, using the Pic microcontroller from Microchip and the Renesas H8S 3644/3687.

pSocs from Cypress and Xylinx FPGA's will feature shortly.

All the Pic projects are written in either;

Structured Basic  from XCSB or in 'C' using the FED Wiz-C compiler.

The Renesas and Cypress controllers  are programmed in 'C' using their respective compilers
