The information there actually dates back to before there was a HAL.... As far as I can tell motion is made up of all the files in the motion folder. motion.c mainly creates hal pins and exports that hal function that is called periodically by realtime: https://github.com/LinuxCNC/linuxcnc/blob/f36ddbe0e0cc43adf379aa430114f67ee26efa30/src/emc/motion/motion.c But I might be misunderstanding what you want to do. If you want to move motion into a different CPU then it probably could be done, by making a HAL interface that duplicates the HAL interface of motmod. (the pin names would not have to be the same) The Mesa and Pico cards already do this. HAL pins are given values, and those values are sent to an FPGA, by various methods (PCI, EPP, Ethernet, SPI....) -- 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, 1916 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
