Hi,
I am evaluating the BLDC_Sensored project on DRV8312EVM. I am not able to correlate the PWM signals and phase outputs.
Here is the picture of the signals as I am observing:
The cyan waveform is PWMA - the PWM signal that goes from the microcontroller to the DRV8312 module. The pink waveform is Phase A with respect to board ground, which is the output if the DRV8312 module. The Phase waveform perfectly reflects the PWM frequency and duty ratio set in the code/expressions window. What I fail to understand is why that is not reflected in the PWMA signal. How else does the DRV8312 module get the information for PWM frequency and duty ratio?
Thanks,
Tamil
