At its core, this repository contains a pin interface libray written in C, which provides a generic wrapper for handling pin/gpio interactions on a microcontroller. The library contains a simple and ...

This project implements a password-based secure access system designed with an STM32F401RE microcontroller. The system manages access using a matrix keypad and provides visual feedback through an LCD ...

Using the analog converter input function of a compact microcontroller’s input pins to read ternary logic encoding allows two pins to sense as many as nine configuration states. Using the analog ...
