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 ...

#include With the descriptor-based interface, prior to allocating and taking the ownership of GPIOs, those GPIOs must have been mapped somewhere. By mapped, I mean they should be assigned to your ...

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 ...

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 ...

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 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 ...

The Raspberry Pi Model B+ was just released, and now everyone who picks one of those up has a few more GPIO pins to play around with. For the millions of people with the two-year-old version of the Pi ...

MCU – STMicro STM32H743 Arm Cortex-M7 @ 480MHz CPU clock An external 64MB QSPI flash for extra FPGA code storage; FPGA – Intel Cyclone 10LP (10CL040) with 40k logic elements, 1,134 Mbit embedded ...

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 ...
