it seems my rs485 on my vfd has stopped working. does anyone have a guide to set it up via pwm?
I cannot get my superlongboard to work with my hyaung VFD vis RS485. is there a way to test both devices to see if the comms are bad on that device?
@best49erfan I’ve combined your two posts/questions, as they appear to be the same issue. There is no need for two open topics.
