When the first Raspberry Pi rolled off the production line back in 2012 it sported a 26-pin expansion header that seemed to conceal endless possibilities. A later upgrade to the 40-pin header we have ...

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 ...

General purpose input-output (GPIO) pins are the simplest peripherals. The link to an object under control (OUC) may become inadvertently unreliable due to many reasons: a loss of contact, short ...

Making car noises with your mouth is optional, but encouraged.

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 ...

For automotive SoCs, GPIO IP blocks are typically developed as Safety Element out of Context (SEooC) and delivered with a set of Assumptions of Use (AoUs). Any risk due to failure of the EE components ...

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, ...
