TMS320F28069: C28x and CLA control routine

Hi every body

I am going to build a buck converter and use digital control library for making the controller. 

is there any simple example about using digital control library to implement a PID controller in c28x and CLA.

basically I want to know how to use digital control library in c28x and CLA. how to pass parameter to asm code in CLA and etc.

thanks in advance

    There is a PI controller example which runs on the CLA on this device in the DCL examples folder. I think that's the closest we have. The controller runs on the CLA while the inputs and output are passed to/from the main CPU. It should be pretty clear how it's done from that example.

    There is a DC/DC buck converter in powerSUITE which I think uses a PID controller from the DCL on the CPU. Details of the kit are here:

    It should be straightforward to stitch together what you want to do from these two examples. I hope this helps. Feel free to post back if you get into difficulty.

    Regards,
