Microcontroller interrupts are one of the big tools in our embedded programming arsenal. They make the chip listen for particular events, and once detected they stop what they’re doing and run a ...

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 everything is not ...

Reading quadrature encoder signals at high speeds (e.g., 1MHz, or, 1m/s with a resolution of 1µm) often requires dedicated hardware. This Design Idea shows a simple scheme to accomplish this function ...
