Hello Everybody,
I am using TMC2130 stepper motor driver to use with my 3D printer. I'm trying to communicate over SPI but it does not work SOMETIMES. :bang: MOSI,MISO and Clock lines are working correctly but CS pin is hanging around 1V. MCU CS pin is connected via 100ohm to driver. MCU side working correctly. I checked the soldering and there is no problem. Does anyone have any suggestion ? My MCU is STM32F103 btw. Thanks for your helps !
