App note: Receiving S/PDIF audio stream with the STM32F4/F7/H7 series

App note from STMicroelectronics about electrically connecting an external S/PDIF stream to an STM32 with an S/PDIFRX interface peripheral, Link here (PDF) The Sony/Philips Digital Interface Format (S/PDIF) is a point-to-point protocol for serial and uni-directional transmission of digital audio through a single transmission line for consumer and professional applications. The transmission of data can […]

An S/PDIF sound card using the PCM2906

Joesugar writes: When S/PDIF became available in the Teensy Audio Library I thought this might be the solution to ground loop problems I’d been having when interfacing projects to my PC.

Hacking Android on the UDOO board (for SATA and S/PDIF)

Computer engineer Primiano Tucci has been experimenting with Android on the UDOO board. I recently came in possession of a UDOO Quad board. The hardware onboard is pretty powerful compared to many other competitor boards. Unfortunately, however, the software support for Android is lagging a bit. In particular, in the latest image shipped by UDOO […]

S/PDIF Digital Audio on the Parallax Propeller

Beth from scanlime has posted a detailed explanation of her development of an S/PDIF encoder object for the Parallax Propeller. The source code is open under an MIT-style license. If you’re a Propeller enthusiast it should be easy to implement this code to give your next sound project a digital output. Beth hopes that this […]
