I have just pushed a feature branch (andypugh/mesa_modbus) to the LinuxCNC github.
It uses the Mesa FPGA UARTs (specifically pktUART) to offer real-time modbus connection directly to a Mesa card. Docs are here: https://github.com/LinuxCNC/linuxcnc/blob/andypugh/mesa_modbus/docs/src/drivers/mesa_modbus.adoc Please let me know of anything that you feel you need to know that the docs omit. At the moment you will find mesa_modbus.c and the modcompile script in linuxcnc-dev/src/hal/drivers/mesa_hostmot2/modbus along with some sample configuration files. Pin assignments and names are compiled-in rather than being determined at load time. -- 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-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
