Each year millions of old smartphones are either tossed as e-waste or are condemned to lie unloved in dusty drawers, despite the hardware in them usually being still perfectly fine. Reusing these ...

Microcontroller dev boards are wonderfully useful items, in testament to which most of us maintain an ample collection of the things. But dragging one out to do a simple job can be a pain, what with ...

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 ...

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 ...

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

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, ...

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 ...

This excerpt, Chapter 14 from the book, focuses pin control and GPIOs — an area of particular importance to embedded systems developers looking to interact with custom hardware devices. This ...
