CCS/DRV8350H-EVM: The Firmware about the DRV8350H-EVM

Tool/software: Code Composer Studio

hello , 

I have tested the DRV8350H-EVM , and it's good . 

My question is about the firmware -- "DRV835X_MSP430F5529_Trapezoidal_Sensored_BLDC" ;

there is my  question , when there is a heavy load on the BLDC , we will loss some speed .

And I have read the code of the DRV8350H-EVM , I don't find there any  code about how to keep the speed  when the load changes .

In fact i don't find there use any feedback of the BLDC's speed to keep the speed stable .

I mean a control method like PID .

So if there no content about it in the firmware or i miss it ?

If there no content about it , can you provide us some about it ?
