think it will be easier to use 5 buttons instead of using a matrix keypad. How would I prompt the user to enter high and low setpoints immediately once the device is powered? With that, how would i configure a button to act as an "enter" button? The reason i ask this is because i want the program to ask the user to enter high setpoint then the user should press enter. The program should then ask the user to enter a low setpoint and pressing enter again will cause the program the jump to the main temperature display.
