Keypad is a library for using matrix style keypads 3x4, 4x4 or 4x5 with STM32.

(Keypad size is limited by IO pins of your MCU.)

You need to convert your project to C++.

Right click on project -> Convert to C++.

Rename main.c to main.cpp.

Library now works with all GPIO ports.

Tested on STM32F1 and STM32F4.
