Testing and coding continues

Serial based CPU card prototype is now complete. I have been writing basic level services to CPU card. Firmware is compiled using SDCC. Schematics for serial based CPU card design are almost complete and i will post it here within few days. Also finnished IO Card chematic and PCB layout will be available at same time. First IC will be programmed using MhProgrammer within few weeks.
CPU design is simplified lot.. DA converters replaced with pwm design.. Power supply stage uses basic discrete components. Both boards are high density but SINGLE sided so those should be easy to build those at home. So you can easily build 2 io module on one 2 sized PCB.

So stay on channell.. MhProgrammer will rock very soon !!!
