SW SPI possible
I need Spi Pins for TMC2130, but i am already using Mosi, Miso and clk for the SD Card.
is it possible to get addional spi pins.
I can not find any software SPI in the files ( Radds and Due configuration )
I think the implementation at the moment only works with hardware SPI. You need to split mosi/miso/clk from the hardware pins. Radds has them available as pins. See wiring in this forum where it is explained. It's in one of the TMC2130 threads here.
