- * #include "keypad.h"
- *
- * // Define your own keypad values
- * char Keytable[] = { '1', '2', '3', 'A',

- * '7', '8', '9', 'C',
- * '*', '0', '#', 'D'
- * };
- *
- * uint32_t cbAfterInput(uint32_t index) {
- * printf("Index:%d => Key:%c\n", key, Keytable[index]);
- * return 0;
- * }
- *
- * int main() {
- * Keypad keypad(p25, p26, p27, p28, p21, p22, p23, p24);
- * keypad.CallAfterInput(&cbAfterInput);
- * keypad.Start();
