TMC2208 V2.0 UART mode #2

Open jgwinner opened 4 years ago

jgwinner commented 4 years ago

I soldered the bridge, as described elsewhere, I get electrical connectivity to the pins on the central chip, but in my SKR Pro 1.1 board, I'm not getting any UART connection to the TMC2208 V2.0 step stick I have.

I'd purchased 4 TMC 2209's for the motors, but wanted to use some 2208's for the extruders. I don't need sensorless homing on the extruders.

How do I get the TMC2208's V2.0 to communicate in UART mode?
