TMS320F280039C: Basic Example of Use of PID Controller within CLA

Reid Anderson

Part Number: TMS320F280039C
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hello,

Is there a basic example that shows how the CLA is initialized, does math, can perform PID calculations, and how it relates to other peripherals? I want to get the CLA involved, but I'm not sure how to use it properly and I've tried to watch every video and read any documentation on the CLA that's out there.

Thanks,

Reid

    Hi Reid,

    I don't believe we have an example doing exactly as you described, but you can take a look at the examples in C2000ware, located in [C2000ware install]/driverlib/f28003x/examples/cla. One of the simpler examples using another peripheral is cla_ex4_pwm_control, which sets up the ePWM module to periodically trigger a CLA task which will perform some calculations on the duty value.

    I'm not familiar with PID Controller calculations; what other peripherals would be involved? Could you describe what the algorithm does at a high level? I can try to provide some guidance from a CLA perspective.

    Best Regards,

    Delaney
