Here’s a Raspberry Pi hack that adds web control using PHP and MySQL. As you can see in the image, it serves up a webpage (using the Apache2 server) which allows you to change the state of the GPIO ...

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 ...

Your MCU/SoC today may have several options for GPIO connections: UART, SPI, I2C. But there are dozens of variations and kinds of GPIO interface protocols: you don’t have enough pins to provide all of ...

Editor's Note: The embedded Linux kernel already play a vital role in embedded systems and stands to grow in importance in serving the diverse requirements of the Internet of Things (IoT). In turn, ...

If one does not need to specify a GPIO at a given index in the list, one can use <0>. The reset GPIO has two cells (two arguments after the controller phandle), whereas CD GPIO has only one cell. You ...

When the original Raspberry Pi was release in early 2012, it came with a 26 pin GPIO output. User access to GPIO redefined the usefulness of a single board computer. As the concept evolved, the ...

Toshiba is developing an interface IC for the automotive CXPI (clock extension peripheral interface) bus whose hardware logic “can control data communication by CXPI protocol and GPIO, eliminating the ...

Welcome to the first entry in the ‘Rarely Asked Questions” blog series. Measuring temperature with a single GPIO is the matter at hand that kicks it off. As the need for sensing capabilities becomes ...

For the lucky few who have a Raspberry Pi board in their hands, you can now use the GPIO pins as a web interface (German, google translation). [Chris] is turning this magical board is turning a small ...
