PID Control Object (with questions)

Hello @ClearMemory041063, @Wilberforce

I am using pid-controller and mqtt modules for our project, now.
We use Wemos D1 Mini.
I am trying the example simulation of the github @Wilberforce, it is working, normally.
However, if we combine the pid-controller and mqtt modules, when we
try to connect to mqtt broker, there is an error.

Execution Interrupted during event processing.
New interpreter error: LOW_MEMORY,MEMORY

Is there any issue for compatibility of pid-controller and mqtt module ?

Regards,
Maman
