Pins 10,11,12,13 on UNO are hardware SPI CS0, MOSI0, MISO0, SCK0.
See if we can move the microstep control (DRV_M0, DRV_M1) and motor enable (MOTORS_ON) elsewhere. 12 is defined as OLED_RESET but not actually connected.
Having builtin motor enabled feedback via LED is nice but should figure out another way.
