I’m designing a board with Arduino Nano Every and I’m not able to communicate through UART with driver TMC2209 V1.2.
I already checked the bottom jumper and it’s ok (default on pin 4).
I’m using pin 2 and 3 from Arduino that all of them are usable as interrupt.
The serial baudrate is 115200. I placed a resistor of 1k between TX and RX and I connect the single wire to UART pin (4) on the driver.
That else should be done?
Many info on web sites but nothing that solve the issue.
I tried to read info like DRV_STATUS but it seems always zero. The driver works fine with the motor.
If you need something, the code, etc, please feel free to ask.
