Diodes has unveiled a 16-bit I/O expander, which enables any digital device to be accessed and controlled over an I2C interface, across a range of input and output voltages from 1.8V to 5V. The ...

This chapter provides general information about ARM ® Cortex ® -M4 microcontroller General-Purpose Input Output (GPIO) Port programming. The discussion is mainly concentrated on the GPIO Ports related ...

This article presents the first of a six-part series of learning the peripheral functions of a microcontroller that is the GPIO (General-purpose Input/Output). It discusses the important peripheral, ...

*The following article was written by Gemini 1.5 Pro. Actual operation has been verified. The M5Atom Lite S3 is a compact development board with a wealth of features, but the limited number of GPIOs ...

Since in our previous tutorial, we only used an LED to blink by using an IO pin as an output. In this tutorial, we will learn how to use another IO pin as an input and control an additional LED.
