PID controller with Jennic 5139..

[royanto]

Hi all.. is there anyone who understand how to program a PID in jennic 5139?
I really need this to control a DC motor over the zigbee network.. I've made several codes but so far all of them still wrong..

The spesification:
I'm using an input potentiometer for the setpoint (through ADC), and get the attenuated feedback voltage from the tachogenerator (through the other ADC)..
then, the PWM output will went through the L298 driver..
