hey guys. i just realised that everything is fine until the actual temperature reaches the respective setpoints. thats when the design starts to really slow down during its operation. i cant seem to understand why this is so.

Refering to post #44

looks like temperature being measured...
keyin = portc : temp = temp + 1 : lowled=temp.3
not sure about that though..

on the lcd will be displayed temperature on the first line and i assuming the binary value of keypressed on line 2
