Details
The keypad buffer stores up to 16 keypad events. Each such event causes the on_kp generation. If your application is slow to process the keypad events, it is possible to overflow the keypad by pressing the keys in rapid succession. Once the buffer overflows, the keypad is disabled automatically (kp.enabled is set to 0- NO). You can re-enable the keypad by setting kp.enabled= 1- YES (this will clear the keypad buffer).
