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 ...

Setting up interrupts properly on a microcontroller isn't easy. The number of times an engineer has set up interrupts in his or her career doesn't seem to make a difference. Configuring interrupts ...

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 ...

Connect your UNO R3 to your computer and configure the ATmega328P's ADC to read its internal temperature channel. Then print the ADC result to the Serial Monitor. For a visually interesting ...

When a WFI instruction is executed or when the processor enters sleep mode using the Sleep-On-Exit feature, the processor stops instruction execution and wakes up when an (higher priority) interrupt ...
