Part Number: DRV8350H-EVM
Other Parts Discussed in Thread: DRV8353, DRV8350


I am trying to evaluate the sensored operation of the DRV835x driver using the DRV8350H-EVM . I followed the  steps mentioned in the EVM user guide (SLVUB78A)  and
I was able to get the EVM work in 6*PWM sensored mode with Hall sensors connected to J2. But I couldn't get it to work in 1*PWM mode
Here is what I did for testing the  1*PWM - Hall Sensor
  • connected the hall sensor inputs to J2, soldered the unpopulated resistors R46, R48 & R51 with 0 Ohm  and selected 5V for hall sensor power (J1)
  •  changed PWM_Mode variable in the Init.c file to 0b1 instead of 0b0 , build & programmed the target
  • The GUI  connected to the  "sensored motor" option. 1*PWM mode was selected.
  •  As I  increased the motor speed (%) from 0 to 18,  the Fault Status Indicator indicated Motor Stall 

To test the 1*PWM - Simple Controller , I removed the resistors so that the state inputs comes from the MCU-GPIO. But still couldn't get it to work in 1*PWM mode
Does the firmware support 1*PWM operation (simple, hall sensor or both ) ?
