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 ...

Digital interrupts represent one of the main concept used in modern computers and embedded systems. In this lab, we’ll explore close the usage of this concept in a real-life situation using one of the ...

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 ...

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 ...

For a number of reasons, including cost, embedded microprocessors have been required to take on tasks for which they are not always well suited. Frequent interruptions from the outside world is one ...

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 ...

In recent years, wireless communications have grown to encompass applications like remote control, remote sensing, and wireless local-area networks (WLANs). The data rates of such implementations vary ...
