PIC Microcontroller Touch Keypad

PIC Microcontroller Touch Keypad

Need a touch Keypad instead of the traditional 4×4 keypads? This might be the way to go.

The actual data from the touch sensors is quite erratic and requires some software processing. Basically you create a pulse for each of the ports and read the data with the instruction following the pulse signlal rise. Then read the ports the same way looking for a gap of 0.1 seconds with no data detected. This does the ‘debounce’. This results in fairly clean data capture from the sensors.
