In designing µC-based systems, you often face a situation in which the µC has to respond to an external event happening at an uncertain moment in time.

Other Stupid Interrupt Tricks We can’t leave the “Good” of interrupts section without mentioning two particular patterns that we use in almost every project with an AVR microcontroller.

This microcontroller architecture makes it difficult to enable interrupts in ISRs. You may, however, use either ISRWait_onK or ISRWait_onV to accomplish your purpose, as in ISRWait_onK 7, 3.

How to manage dynamic power in a microcontroller using its non-maskable interrupt By Ajit Basarur, Shantanu Prasad Prabhudesai, and Nazmul Hoda, Ittiam Systems pldesignline.com (August 06, 2008) ...

Riding the PC/104 bus in the company of a PIC18F8722 microcontroller from Microchip Technology, the MC104P controller module provides access to external memory and interrupts in the same manner as ...

This bit can be polled by the microcontroller, or an interrupt can be generated when it changes state. Additionally, analog-to-digital converter (ADC) in the microcontroller can measure the MVIO power ...

Both devices offer the same functionality and pin-out, as well as also offering 10-bit resolution, an eight-channel A/D converter, and eight external interrupts.

Microcontrollers are integrated microprocessors that include the memory, peripherals and interfaces, as well as the CPU, on a single chip, making them a cost-effective solution for embedded systems ...

We love interrupts in our microcontroller projects. If you aren’t already convinced, go read the first installment in this series where we covered the best aspects of interrupts. But everythi… ...
