Possible to use stepper dirvers with THB6128 chip ?
Hi!

I have some Raps128 stepper drivers that I did plan to use on my brain shield.

http://doku.radds.org/dokumentation/raps128/

There is two thisngs that may cause problems?

1. Raps128 need inverted activation signal Enable = HIGH (at Pololu drivers enable = LOW, invert in firmware!) - possible to set in the code?

2. Stepping mode - if default mode is 1/16 that is 1/128 on the Raps128 = to high/low torque
   

If the default stepping mode on the brain is 1/16 - is it possible to alter the mode?

Or do I have to order some A4988 ?
