PID

PID controller for Atmega32

---

PID controller details have been came bellow:

• Changeable coefficients for P, I and D
• Each coefficient should be edited by user between 0 and 16
• Working point can be set by user from 0 to 2.56 Volts.
• Sampling time should be 20ms
• Input signal has a amplitude between 0 and 2.56 Volts.
• Output is a 8 bit number on Port C showing a value between 0 - 2.56 Volts
• When Atmega32 is not working on PID coefficients it work as a timer and increase a value which is on 200H to 205H of RAM.
• When system starts it'll be reset and counter will become 0
• After 16 mins 5 byte of counter will be sent to Port D in a little-endian mode.

Develop

You should use Proteus 8 and WinAVR compiler so that you can open main.c code in Source Code tab by right click on ATMEGA32 and click on Edit Source Code.
