FMC Motion Front-End (fmc-mfe)

Project description

The FMC Motion Front-End (fmc-mfe) aims at providing an analog and digital environment for the control of up to 8-axis. It can also be used as a general purpose analogue module.

This design is meant to run on the SPEXI7U or DIOT system board cards both based on Xilinx MpSoc Zynq UltraScale+.

GRBL motion software has been ported to Zynq US+ to drive the card.
