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 ...

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 ...

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 ...

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 ...
