How to get two slow PWM outputs based on one analog input (from PID)
How to get two slow PWM outputs based on one analogue input form a PID function (or from all other kind of analog value) ?
This subroutine provides two digital outputs:
- one for the «hot» function
- one for the «cold» function
with slow PWM function over a given period depending on an analogue input, a setpoint and the selected period
- PID_Output: The analog input value from, most of the time, the PID output tool
- PID_OutMax/Min: The min and max value of the PID_Output value. (For determinate the total range of the analog input)
- PID_Target: Where you want to go
- Periode: Total periode of the slow PWM
- GoUp/GoDown: 2 digital outputs for the «Hot» and «Cold» fonction
