The new Raspberry Pi Zero is generating a lot of discussion, especially along the lines of “why didn’t they include…?” One specific complaint has been that audio is only available through the HDMI ...

Raspberry Pi owners looking to use higher voltages with their mini PC, might be interested in this new opto-isolator board called the Opto-pi which has been specifically designed to be used with the ...

Now instead of wrangling Python or PHP to do your bidding, [Eric] came up with a way to control the GPIO pins on his Raspberry Pi in a browser. [Eric] calls his project WebIOPi, and it’s the perfect ...

How much can you cram into a 2.6 in x 1.2 in circuit board? You'd presume not much, but the Raspberry Foundation is trying to prove you wrong. First, it added built-in Wi-Fi to its teeny Raspberry Pi ...

This application note presents the CS4201/CS4202 audio codecs, and how to implement headphone jack sensing using the GPIO (general-purpose input/output) pins. It briefly introduced headphone jack ...

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 ...

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 ...
