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 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 ...

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 ...

Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to ...

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 ...

Traditionally programmers and organizations have had an irrational fear of using interrupts. One might think that statement is facetious but on more than one occasion in the last year the author has ...
