Tool/software:
I have had good success using the Stepper Driver. However, when trying to detect a disconnected motor, I am unable to latch the OL bit in the FAULT register. All control is via SPI. The programming is on an Arduino platform (M0+ controller) with a Pololu software driver. The software driver and the Motor Driver have worked very well up to this point, with successful speed, direction, and DAC control.
Vref is 0.670 V
TRQ_DAC is 75%.
CTRL4 is 0x08. I tried 0xB8
Microstep_Mode 0x01
A tight loop test routine executes 20 steps with 2 ms between steps in the hope of triggering a OL.
FAULT register returns 0x00 after the 20 steps.
Suggestions appreciated.
