I'm working with a stepper motor, DRV8711 Booster Pack and a MSP-EXP430F5529LP.
In my code I am:
1. Resetting (active high)
2. nSleep (active high)
3. setting direction bit
4. Writing to ENBL via SPI
5. Lastly, toggling STEP around every 300 ms
For what I can tell, I have configured the CTRL register to enable the motor. The problem is I see my signal being sent via SPI but I can not getting any read data back to confirm the writes.
I am also getting a fault when I run the code. I am sending 12 V to VM.
Once in a while the motor will move but it's more of a twitch...ANY help would be grateful!
Thanks,
