Hello,

Quick question: Is the MSP430FR2033 capable of PID control?

Sure, but the devil is in the details like whether it is fast enough for your application.

Ah man, I need to move micro servos based off O2 concentration, but I don't think the change has to be super fast. I suppose the calculations have to be done quickly.

Just stay away from floating point. Arduino has a PID implementation, you could probably use that as a start for your code.

How slow or fast do you think this MSP430 is?

Hi Anish,

This MCU has a 16 MHz clock.

Best Regards,

More than fast enough for RC servos.
