Interrupts are the name of the game for more functional microcontroller firmware. [Rajendra] just posted a tutorial covering all of the interrupt types for the PIC 16F688 microcontroller. He gives … ...

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.

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 ...

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.

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.

10 Pain-Free Steps to Configuring an Interrupt Controller Setting up interrupts properly on a microcontroller isn’t easy. Thankfully, there are steps that can be followed to alleviate these painful ...

A primary goal in the design of this 8-bit microcontroller was that it support fully deterministic software execution; that is, every instruction would execute in a specific, predictable amount of ...

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) ...

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 ...

A number of low-power features are available in the Cortex-M0 and Cortex-M0+ processors. In addition, microcontroller vendors usually also implement a number of low- power modes in their Cortex-M0/M0+ ...
