Reading Reference Switch Input for TMC5072

[antonyjohne]

Hello!

I'm currently using Pytrinamic with TMC5072 EVAL for controlling my motor. However, I'm having a hard time configuring the code to read a switch input on the REF/L1 pin of my module. The L1 input pin also seem to be providing 5V output when measured with a multimeter (I'm assuming because of an internal pull-up resistor). How should I configure the code to accept stop-switch inputs on the L1 pin and continually motor the pin to stop the motor when the switch is pressed?
