HQCT-eA vol control from RR etc
I've been working on extending and fixing the Datalex code for my HQCT-eA. It's mostly working now (although I've not yet got TA done). I originally planned to do a DLL, but it seems you've beaten me to it!
So far as the eA version is concerned there are a few things that I thought might be worth mentioning that might be of interest to you:
- It's really useful to control the amplifier settings from RR etc. So, I've added a number of new windows messages to RRHQCT.exe - things like selecting the input source, changing volume, treble, bass etc. I've amended RR to use these rather than the usual Windows mixer which of course doesn't work with the eA (actually, I guess one could fix the eA's volume level and then adjust the sound card vol level, but this wouldn't work when the radio was selected and there would still be no bass/treble/fader support).
- It's a similar story with FreeDrive when one wants to hear a sat nav voice guidance - one needs to temporarily switch the amp's input source to the sound card and then back again to whatever was selected before. I've added a message to RRHQCT and changed FreeDrive in the same way as RR (which was easy since it's basically the same code as RR - thanks CDRSkull!)
If these are useful to you, let me know and I'll forward the details. I'm also happy to contribute the RR & FreeDrive changes back to whoever is maintaining them.
Finally, I have a (perhaps stupid!) question for you on AF. In my testing I noticed that it can sometimes take some time for the best AF frequency to be acquired (in my case 94.5MHz when tuned to a weak alternative on 93MHz). I noticed in your test program (RDS.EXE) that there is a column called 'This' which in my testing seems to have the best frequency (94.5) shown in all rows. What exactly is this column? If this is a dumb question then I my only defence is that I'm using Diogenes's code for AF and haven't yet delved into the RDS spec (all 150 pages of it)!
Thanks in advance,
