Handheld devices including smartphones and Tablet PCs have touch screens and many buttons for different functions. In order to save battery power, if the screen is not touched or the button is not ...

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low-cost MCUs offer limited ...

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 ...

In a System-on Chip(SoC),a general interrupt process works as follows: Interrupt is triggered by a certain system event or interrupt source. Interrupt is detected by system’s peripheral module, which ...

Related to being powered by a super capacitor, I also need to get my ATtiny to go to sleep when not processing anything. And that involves setting pins to ‘interrupt-on-change’ and getting the chip to ...

This paper provides a complete solution to the GPIO Verification for any SoC. GPIO interface is available in every ASIC. To avoid duplicate efforts and (save) time to verify the GPIO interface, we ...

Eindhoven, Netherlands: A new family of 8- and 16-bit general-purpose I/O devices (GPIOs) from NXP Semiconductors expand the two wires of the I 2 C bus into eight or 16 GPIO pins. These can interface ...
