I could really use a leg-up on my rpi5 .hal. I try to be reserved and not overuse your talents but I am really at a dead-end. I have read countless threads on hal development but have seen nothing that will get through Axis launch w/o throwing an error. I have 10 years experience with emc2 on my homebrew 3 axis machine. The GPIO conversion is the difference.
My challange is to simply invert ydir. You can see some of my failed solutions in the "Stepper Outputs" section below. My hal file is based on the RPi5 file provided by Byte2Bot (I am using their parallel V. level conversion board) but they did not deal with GPIO output inversion. And I have not found one other indication that anyone else has either.. Advanced HAL doc. has about 4 lines on the setp command which are too obscur for me. I asked a couple AI bots with no help. Chatgpt4 suggested this:
loadusr -w hal_invert
addf hal_invert.0 servo-thread
net inverted_stepper_direction <= hal_invert.in
net original_stepper_direction motion.stepper.23.dir
net direction motion.stepper.0.dir => inverted_stepper_direction
....to be placed at the front of the Stepper Outputs section but it looks very foreign and posts errors on launch. This is the now defunct code in my old emc2 hal: setp parport.0.pin-03-out-invert 1
If anyone has any ideas of what to do or has seen a .hal example with a pin inverter command for RP5 parallel output please let know.
