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 ...

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 ...

A computer cannot meet its requirements unless it communicates with its external devices. An interrupt is a communication gateway between the device and a processor. The allocation of an interrupt ...
