Hi,
I wonder if anyone can tell me if the MIAC V2 can cope with a PID control algorithm performed at the same time with other tasks?

How can I determine if the the tiny PIC18F4455 is succumbing under the pressure of a PID processing algorithm and other duties performed at the same time?

I need to keep a gas vessel at a constant pressure while the temperature of the vessel itself is varying by playing with two solenoid valves, input gas and output gas.
This process is supposed to be very slow.

Hello Giovanni,

The MIAC should be able to do PID control. However it largely depends on your implementation.

Are you using the DSP components or your own mathematics?

Are you using Flowcode 6 or Flowcode 7? This might make a big difference especially if you are using Floating point variables.
