TDC is nothing more than one kind of user defined groups.
Using the mrdsio.dll fill UDG1 buffer and set the UDG1EN byte so the group from the buffer will be transmitted once.
The group structure is described in RDS standard or in the PIRA32 manual page 53 (http://pira.cz/rds/manual.pdf) including examples.

« on: May 23, 2012, 02:23:53 pm »I have an EDM transmitter that I believe has a MRDS192 in it that I use at local swim meets to announce events. I thought it would be neat to be able to send current event/race info via RDS and have developed an app to do so using the mRDSio.dll library.
Now, I want to use a large outdoor LED display I have as well. I'm working on an Arduino project that incorporates the SI4735 tuner to extract RDS info and send it on to the sign. For the sign, I'd like to have a little different set of messages and noticed the TDC (transparent data channel) RDS option and the IH (in-house applications) RDS option. I understand regular FM radios would simply ignore this data. But, I don't see any mention of these in the MRDS192 documentation.
Can I get to these somehow via the MRDS192? Or, could I use user-defined groups in some way to accomplish this?
Thanks for any help you can give me...
