TI Stepper Drivers DRV8818 and DRV8824

I’ve been working on a XMOS CNC controller board and in the process came up with two prototype designs using two different Texas Instruments stepper driver IC’s. The DRV8818 and the DRV8824. ┬áBoth of these ended up being able to control the NEMA 17 steppers for RepRap and the NEMA 23 for my small CNC router .
