There are elements of this to the STMBL servo drive, in that it uses the STM32 to count encoder (and resolver and SSI) encoders then reports back to LinuxCNC using the Mesa smart-serial protocol. This is a neat choice, as Smart-Serial is self-configuring. Plug in the device and all the appropriate HAL pins appear as if by magic. Smart-serial is still one cable per node, though. It's a star topology. But if it will work for you, then the smart-serial STMBL code for STM32 is there on the STMBL Github. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
