hi all
i want to design a temperature controller using lm35 and pic16f876 and control the heater through pid method.
i have finished with the lm35 temperature display with pic.
now i am stuck with pid. i have to control heater with user programmable "p", "i" and "d" seperately.that means . if the user sets a value of p then the control of heater should change accordingly. similarly other two.
i haveto make software programmable pid.
how to do this.please help me out.
thanks to all
