Why Buffer? Because buffers cut you some slack. Inevitably, in our recent series on microcontroller interrupts, the question of how to deal with actual serial data came up. In those examples, we were ...

On the lower end of the performance spectrum, many widely available and inexpensive microcontrollers pay for their small pc-board footprints by omitting functions. For example, most low-end processors ...

The Deferred Procedure Calls and Interrupt Service Routines is a mechanism in your Windows computer that will defer tasks of lower priority to a time suitable and simultaneously prioritize high ...

Callbacks are references to executable code that higher levels of software pass into a function. These callbacks have the ability to greatly increase the portability and reuse of embedded software, ...

Interrupting while someone is talking is rude for humans, but smart for computers. [Ivan Voras] shows how to use interrupts to service the ESP32 analog to digital converters when sampling sound.

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...
