Copley has a data sheet available for the 513 but it does nothing more than mention the internal header. I contacted them and they said that they are unable to help out with anything that old. Does anyone have info on the internal header that is used for some of the settings, and the equations or

If you have to use on chip peripherals such as DMA, ADC, or PWM you very much have to "learn a chip" (some are part of the core, some are part of the silicon manufacturer implementation.) An Arduino OS will sield you from much of that but if doing more bare metal implementation or even running a

I use AutoDesk's "Fusion360". It's free for most of us. Of course it will open AutoDesk's DXF file format. AutoDesk has gone a 180 degree turn on pricing making a premiere CAD/CAM program free. Fusion360 should be popular with anyone doing CNC work. It allows one to make 3D models and then
