Other Parts Discussed in Thread: DRV8312, STRIKE, DRV8412, CONTROLSUITE
I am trying to run PM Sensorless project with TMS320F28069 on DRV8312 and facing following issue.
1. at project level 1 when I am checking the PWM A, B and C on oscilloscope I don't get any pwm on DRV8312 board however when I mount my TMS320F28069 on seperate docking station I am Getting PWMB and C but PWM A is not coming ( I see a pwm like waveform on PWM A as well but amplitude is very low)
I am unable to make any conclusions and would require some help how to debug this issue.
Just to strike down any issue with DRV8312 I have successfully ran other bldc project and I am getting all pwm and motor is running.
One solution that I am trying to evaluate is follows and have following question
1. I am trying to replace pwm module of PWM a in SW with some other module for that what hardware changes will be required?
2. When I open PM sensorless project I see a comment at top mentioning software is developed for DRV8412 but project document and all refer to DRV8312
kindly guide me so that I can debug my issue.
Thanking in advance
