Other Parts Discussed in Thread: DRV8850EVM Hey,
I have a DRV8850EVM board and am trying to use the external signals (IN1H, IN1L, IN2H, and IN2L) to control a motor. All I could find in the datasheet that I needed to do was to remove resistors R5…
I think that was what was happening as I saw glitches on the FAULT pin but the current measurements weren't showing that it should be tripped.
I just ran a quick test where I stop the motor before changing direction and curiously I saw a slight increase…
Hello,
Yes, it is possible to change the speed by changing the output duty using the MCU. You can get an idea of how to do this by looking at the DRV8850EVM.

David,
Got it...I was just going off your earlier post where you said other motors worked perfectly. Seems that has changed as well.
Thank you for your feedback. I think the only thing we haven't ruled out is thermal effects. Do you have anyway to…
I found the problem. In the example code that came with the DRV8850EVM they did not configure ADC10CTL1. Since they used P1.0 the default configuration configured P1.0 so since I changed the ADC pin I had to add:
ADC10CTL1 |= INCH_5
