In the last installment of our tutorial series we built a simple circuit on a breadboard and programmed an ATmega168 to make it run. That proves that you know how to follow directions, but the eureka ...

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 ...

[Tim’s] new version of Micronucleus, Micronucleus 2.0, improves upon V-USB by removing the need for interrupts. The original Micronucleus was a very small implementation of V-USB that took up only 2KB ...

Structure and timing of typical microprocessors. Sample microprocessor families. Memories, UARTS, timer/counters, serial devices, and related devices. MUX and related control structures for building ...

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 ...

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 ...
