Slave PID algorithm or Master PID algorithm

[sixhotdogneck]

Is the PID algorithm in Brewery Automation Software normally implemented on the slave microcontrollers (Arduino) or is it implemented in the master controller?

I would guess if it's in the master controller you'd have to have some fail safe if communication was lost with the slave (microcontroller) (or any other number of errors that could occur).

In BruControl, it’s in the microcontroller. This is done for increased reliability and timing accuracy, but certainly there is no way to guarantee 100% failsafe operation.

Good to know. That must make for interesting code on some of these microcontrollers.

@BrunDog do you custom code these algorithms for each microcontroller you support?

Nah... we let the compilers do the work!

Nice. So you coded it in C or some cross-platform language (or cross-platform platform?).
