Keypad to ESP32

Software Development Project Development
#1

Hi

For a school project I must to use a Grove - 12 Channel Capacitive Touch Keypad (ATtiny1616) with an Arduino ESP32 Wroom32 but I can’t do it. I have search on a lot of forums and websites but these never are used assembly. On forums, people use keypad with 7 pins but my have just 4 pins (GND, VCC, UART TX, UART RX).
I search to receive numbers which are typing on the keypad to check if it’s correct to open the door.
