Does it work with DC Servos?

Yes, but DC servos usually operate at a much lower voltage, and the IGBT module we use is not very efficient at low voltages.

Does it work with stepper motors?

No.

Why do you use 2 CPUs?

The driver is designed to run of rectified mains, without a transformer. Therefore the high voltage side has to be fully isolated. Here we need to supply about 8 digital I/Os, and measure many analog values. The cheapest way of doing this is to use a second CPU, and only isolate a UART. The communication is running at 3Mbit, but 9Mbit is possible.

Does it work with +-10V?

No.

GCC complains about missing files.

Use the Makefile. It generates code at compile time.
