On the lower end of the performance spectrum, many widely available and inexpensive microcontrollers pay for their small pc-board footprints by omitting functions. For example, most low-end processors ...

Version 1.1.0 of the library has been released. We add support for the ATmega2561 and 1281 chips, with pinouts defined from the MCUdude/MegaCore project. Code donations by Kizmit99. Plus, a ...

Handheld devices including smartphones and Tablet PCs have touch screens and many buttons for different functions. In order to save battery power, if the screen is not touched or the button is not ...

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low-cost MCUs offer limited ...

An infrared (IR) sensor a proximity sensor, or a ‘nearness’ sensor senses whether there is an object near it or not. The IR stands for Infrared sensor. Infrared is the light out of our visible ...

Setting up interrupts properly on a microcontroller isn't easy. The number of times an engineer has set up interrupts in his or her career doesn't seem to make a difference. Configuring interrupts ...
