Re: UDRC

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:
  • COS and PKSQL (digital and 'analog tone' squelch) input
  • PTT and REMOTE (take over) output
  • 4 mode setting pins output

Audio:
  • Discriminator audio from the DR-1X
  • Audio from the DR-1X
  • Tone In/Modulator to the DR-1X
  • Audio to the DR-1X

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.

Is there any documentation on programing the UDRC?
