hi all,
I am a bit new to microcontroller programming,but anyway.
i have built a TRIAC based UV heater controller,i am using two keys for inr. and dec. of the power to heater which are in continuous polling, then one port line is used to fire the gate of TRIAC, whose timing has been calibrated thru' tmr0, also i have interfaced two seven segment LED displays for showing the percentage of power given to heater these displays are multiplexed and uses tmr1.
Now, i want to upgrade my system, i want to control the power given to heater thru' infrared remote control.
As u can see that i have been left only with one tmr i.e tmr2 and want to detect two frequencies of IR remote, how can i interface the IR sensor ,
also if anybody knows how the hardware configuration for it would be pls suggest.

thnx
