Pica tmc2130 spi


Hey, so I need a little help configuring the TMC 2130 silent step stick drivers. I’ve found the SPI pins in the LCD headers (sclk, mosi, miso) but I don’t know which pins to use for the four “chip select” pins. If I’m not using an LCD, can I just use any of the other LCD pins? I also don’t know how Marlin has the chip select pins configured by default.

If anyone has experience with this I’d greatly appreciate some advice.
