MhProgrammer / News: Recent posts

All development is now done directly to cvs repository. So, follow progress from there.

Next package will be created when you are able to program first IC with this programmer.

There are still few bugs in CPU-PCB module.
Lot of work have been done with PC side of software but still some modules are missing.

Lot of time has been spent writing module tests, so writed code should be quite bug free.

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.... read more

I started to build first prototype of device and it is progressing well. Curently power supply module is under testing. CPU card and IO modules are also ready and waiting testing. During prototyping i changed design radically. All these changes are made to lower overal cost of programmer and make it available for more people. Now programmer uses 5v volt instead of 3.3 and USB connection changed to serial. Power supply will be build from well available parts(lm317 based design)
I will update schematics when i have done some basic tests to device. I have also started to code PC side of software. PC side software will be object oriented C++ design.

First version at last available at sourceforge.
