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
