[Grbl_Esp32 Issue#610] spi pin definitions

Hi, I’d like to define my own set of custom pins for spi if possible (for use with TMC5160). Having scoured the source I have only found reference to the CS pin and spi_index which is presumably 0, the default define. Why would I would want to do this you ask? Because I’ve already made the board, foolishly without looking at the existing designs and noticing they used the standard pins….

Where/how could I do this? Or am I buying a ticket to bodge wire central?

My esp is connected to the 5160 as follows

IO17 = DIR
IO5 = STP
JP1=DC0
IO18=SDO (not IO19)
IO19=CS
IO21=SCK (not IO18)
IO22=SDI (not IO23)
IO23=EN
IO16=Diag0
IO4=Diag1
