I have stopped working on my ATMega based quad channel servo controller - it simply won't achieve the performance I want. I'm using it to run my mill at the moment, but it's not going to allow me the full speed/resolution I want.
A few people have asked for design files, and I'm happy to share them if you think it'll help you.
THESE ARE THE FILES FROM WHEN I STOPPED WORKING ON IT YEARS AGO.
THEY MIGHT NOT EVEN WORK/COMPILE.
Firmware
AVR Studio (4?) source files
Schematics & PCBs
These were made at a time when I had access to Altium Designer, which I now do not. You may be able to view the design with Altium Designer Viewer but I have not tried. I don't have access and cannot provide them in another format.
Questions
If you've got questions, I'm happy to try and answer them... but:
- I really don't remember too much about the specifics of the code/board.
- I don't believe it's a viable solution and has a future.
- For general control loop information Wikipedia has all you need.
