Is there any documentation on programing the UDRC?

It’s essentially just a soundcard. It will show up in ALSA just like any other sound card. It supports the S16_LE and S32_LE formats and the following sample rates: 8000 16000 22050 44100 48000 96000 Is there some specific information you’re looking for? -- Jeremy McDermond (NH6Z) Xenotropic Systems mcdermj@...

Is there some specific information you’re looking for?How about an UDRC python layer on top of the standard python GPIO library that makes it easy to turn on the PTT pin to play over the local repeater the audio of K7UDR promising to have the the product ready by last weekend. Bill

Documentation is tied to product release. If one knows how to open audio devices under Linux and manipulate GPIO pins on a Raspberry Pi, then one has the basic knowledge to program the UDRC. I use WiringPi for GPIO manipulation. Source of the dstarrepeatercontroller will be generally available for examples. On the HD-15 connector (used to connect to the DR-1X) there are unbuffered GPIO pins for:
Audio:
Ground and Power (The UDRC and Raspberry Pi are powered from the repeater) The mini-din 6 will follow amateur radio convention, however the control pins will be buffered because of potential voltage differences. More advanced topics will follow basic documentation.
