My current project is getting the cnc interface figured out, any help would be great. For now my direction is to use the GPIO headers as a direct step/dir end stops, spindle control etc... setup. I'm trying to put together information on what the best plan for the board would be. Any advice is more then welcome. I'm currently amassing different HAL_GPIO.c file versions with different design logic idea. SPI HAL and others. My ideal goal is to get the GPIO port to work like a parallel port in function. If I have to go external hardware like mesa or some other system I will, But I consider it last resort. The next task is tuning the system for performance. It has been suggested that one of the cores be isolated for RT functions only.

on the Grup you can just do a ISOCPU
"isolcpus=2,3" as many you like you can also check if not the first is the fastest and use that one with the lowest latency
