I am trying to use a stepper motor driver with UART and convert it with MAX485 chip. The driver needs RS485 two wire half-duplex.
For my script I am using Python3.
However I can’t get any type of connection to my driver. I think It is because of the connection to/from the MAX485 chip.
With python code I can’t even see a connected serial port.
import serial.tools.list_ports print(list(serial.tools.list_ports.comports(include_links=True)))
Output: [ ] #no port detected
NOTE: The expansion header is from Raspberry, because it was already in my library and nearly similar to the Nvidia Nano
