PWM timing diagrams DRV8301LS12

Other Parts Discussed in Thread: TMS570LS1227

Hi,

I need to measure and plot the timing diagram for the FOC motor control using DRV8301LS12 with following data

1. Time at which ADC start conversion interrupt generated,by PWM module

2. Time at which ADC conversion is completed

3. Time at which new PWM updated in the timing moudule.

4. Speed control loop start and end timing

There is no additional pins available for me to configure the contoller GPIO to indicate the above said data in the evaluation kit.

Is it possible to get exact data by configuring the graph in code composer studio?

Also could you explain how to use DAP for real time debugging. 

I am using code composer studio 5.5.0.0007

Evaluation board: DRV8301Ls12x with TMS570LS1227 control card.

XDS100V2 for debugging.

Control: FOC for brushless dc motor with encoder

Thanks & Regards,

Rathinavel
