In the interrupt method, the device that needs the microcontroller’s service notifies it by sending an interrupt signal. The microcontroller stops whatever task it is doing whenever it receives an ...

What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...

Welcome to part three of “Interrupts: The Good, the Bad, and the Ugly”. We’ve already professed our love for interrupts, showing how they are useful for solving multiple common microcontroller tasks ...

Designers of microcontroller-based products that require a keypad for user data entry can select from dedicating an input line for each key, continuously polling the keypad's x and y lines, or ...

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 ...

As portable systems become increasingly power-conscious, the need for smart power management becomes equally important. Besides the main processor, an auxiliary Microcontroller Unit (MCU) often ...
