Plenty of work to do P?
Well, it gives me good hope to know that -eA works!

Right, having popped out to PCWorld and picked myself up an external USB SB Live box I've noticed my amplifier has a couple of small problems. They are not related to this thread so I shall post them on the hardware thread.

Luc,

I maybe asking alot of you here so please be direct

what I could do with initially to get -eA working is a method of selecting the desired input (i.e. CD input) and adjusting the amp volume independent of CPCTuner that can be controlled via RR.

Is that something you could do please?

Edited to add: It just occurred to me that RR needs to know to talk to the -eA and not the sound card

I'm not sure if this is doable?

Damn I just bought the HQCT -e hope the detection issue is easy to solved as I should have it by next week.

How direct would you want me to be as I saw just a minute ago that you ordered a Silabs USB dongle?

Don't worry, I'm not gonna blame you for anything. I also have a Silabs radio but never used it in my car, tests indoors proved to me that I could save myself the trouble of soldering a coax to the thing. Now you can also compare HQCT with Silabs in a while and you can draw your own conclusions then.
The interface part in CPCTuner is changed on PaulKaye's request, he's building a plugin for RR to use for all HQCT functions including switching audio sources, full sound control like volume, bass, treble, balance and fader change and more. Only thing is that it's been a while since we had contact, I need to send hime an email to see how he's doing and if he made any progress lately. I still need to do some testing/debugging on the subject, the code is already implemented but is not stable yet.

Regards,
Luc

Give up?!!!!
I bought the first parts for my carputer on ebay two years ago and my car is getting older by the decade :-)

Heh

I plumped for the Silabs cos I'm driving around 2,500KM per month with no audio and only my only company and it's driving me bonkers.

It'd be great to get the HQCT running at some point seeing what it cost me and it's size and packaging is great which means it's easier to tuck away!

I tested my mac and external SB Live hooked up to my Genesis amp and was very happy with the result, no noise at all. Just some weird noise from the SB Live until the drivers load. The genesis amp doesn't fit in the small spaces that the HQCT can tho.

Be great to see some software support for the -eA soon

I'm laughing cause my car PC has taken 2 years to build too

Understand what you're problem is, I'll see what I can do to get the -eA and RR back on track again and to put radio in your car. My second problem (apart from a shortage of time) is that since I changed jobs I also have a new (company) car with no car-PC installed, this is why I also need to do a completely new build. This means that I have radio (pre-installed) in my car but no PC. We need to organize a poll to see what is worst

.

And about my first install it wasn't even finished before I had to take it out of the car. But this gives me the opportunity to start again, avoiding all the mistakes I made in the first install.

Cheers,
Luc

The Silabs stick is nice and cheap and I can use it in the house when the -eA is working, the plan was to sell the Genesis 4 channel amp once I was happy with the -eA's performance as well.

Hello,

Here's the code from CPCTuner that handles the RR interface commands:

Code:

   // RR_V holds value after ';' when the command is numeric
   // RR_C holds RR command
   // RR_C1 holds value after ';' when the command is alfa-numeric
   // HQCTuner is the HQCT object
   // SendToRR is a function that sends data to RR
   case RRCommand of
      tune   :
         begin
            // Check if we have to switch between AM/FM for new frequency
            if (RR_V < 6700) then
            begin
               // New AM freq from rr
               if HQCTuner.FMBand then
                  HQCTuner.FMBand := false;
               if RR_V <> HQCTuner.FrequencyAM then
                  HQCTuner.FrequencyAM := RR_V;
            end;
            if (RR_V >= 6700) then
            begin
               if not HQCTuner.FMBand then
                  HQCTuner.FMBand := true;
               if RR_V <> HQCTuner.FrequencyFM then
                  HQCTuner.FrequencyFM := RR_V;
            end;
         end;
      seekup : HQCTuner.ScanStations(ScanUp,   false);
      seekdn : HQCTuner.ScanStations(ScanDown, false);
      mute   : HQCTuner.Mute         := not HQCTuner.Mute;
      step   : HQCTuner.FMStepOffset := RR_V;
      source :
         begin
            case TRRSource(ansiindextext(RR_C, RRSource)) of
               // TunerSrc, CDSrc, PhoneSrc, NaviSrc
               radio : HQCTuner.SoundSource := TunerSrc;
               aux1  : HQCTuner.SoundSource := CDSrc;
               aux2  : HQCTuner.SoundSource := AUXSrc;
               nav   : HQCTuner.SoundSource := NaviSrc;
               phone : HQCTuner.SoundSource := PhoneSrc;
               else
            end;
         end;
      setvol      : HQCTuner.Volume := RR_V;
      setbass     : HQCTuner.Bass   := RR_V;
      settreble   : HQCTuner.Treble := RR_V;
      setmute     : if (RR_V > 0) then HQCTuner.Mute := true else HQCTuner.Mute := false;
      switchinput :
         begin
            if copy(w_s, Pos(';', w_s) + 1, 2) = 'on' then
            begin
               // Save current source
               CurrentSource := HQCTuner.SoundSource;
               // switch to new source
               if LeftStr(w_s, 3) = 'dio' then
                  HQCTuner.SoundSource := TunerSrc
               else
                  if LeftStr(w_s, 3) = 'ux1' then
                     HQCTuner.SoundSource := CDSrc
                  else
                     if LeftStr(w_s, 3) = 'ux2' then
                        HQCTuner.SoundSource := AUXSrc
                     else
                        if LeftStr(w_s, 3) = 'nav' then
                           HQCTuner.SoundSource := NaviSrc
                        else
                           if LeftStr(w_s, 3) = 'one' then
                              HQCTuner.SoundSource := PhoneSrc;
            end
            else
               // switch to previous source
               HQCTuner.SoundSource := CurrentSource;
         end;
      rvol    : SendToRR('rvol;'    + IntToStr(HQCTuner.Volume));
      rtreble : SendToRR('rtreble;' + IntToStr(HQCTuner.Treble));
      rbass   : SendToRR('rbass;'   + IntToStr(HQCTuner.Bass));
      else
   end;

It's possible to control the following CPCTuner functions:
- switch (frequency AM/FM)
- seek (a station up)
- seek (a station down)
- mute (toggles)
- step (step is used when CPCTuner starts seek, be carefull, no value check yet, use 10 for 0.1Mhz in FM; 20 for 0.2Mhz)
- source (switch between audio sources)
- setvol (change volume between 0 and 68)
- settreble (change treble between 0 and 7)
- setbass (change bass between 0 and 7)
- setmute (0=unmute, 1=mute)
- switchinput (switch between audio sources, special)
- rvol (read current volume)
- rtreble (read current treble)
- rbass (read current bass)

A lot of these functions are specified more in detail in this post from PaulKaye.

So if you need to change the volume in the -eA version, use the setvol command with a value between 0 and 68, or the source command to change between radio/CD/phone ... So all you have to do is add a slider or button to RR and send the correct message.

Have fun!

Luc,

I'm very new to RR, are you saying that a suitably modified RR skin is ready to control the -eA via CPCTuner?

All the tuner functions worked, but I couldn't swap sources nor control volumes or tone.

Cheers

Carl

Hi Luc!

I downloaded the new 1.1.1.50. Small change in log file. http://web.comhem.se/bengt-olof.swing/20071130Log.txt

I also tried the new dll and runned it with vb example. I did <start>, end then pressed <FM>.

Do you get any clues from this?

Cheers, B-O

Ps.
One little ide. If the logfile contains version info there will be no question what sw that was acctually run at the time.
Ds.

Yes, I modified the interface (Windows messages) so that the -eA version can be controlled via RR. Of course RR needs to be modified for this. The description of the messages can be found in my previous post. I also have a little test program I use (see attachment), its very simple. Start the test program, then start CPCTuner and you can control CPCTuner by typing messages in the text box and push enter or the Send button. The listbox shows messages that are sent to RR. You can use this tool to help test the commands that need to be send to CPCTuner.

You mean via RR then? This is normal, RR doens't send the right commands yet to CPCTuner to change volume, source and or tone.

I will send an email to PaulKaye tomorrow and ask him if he has made any progress on his -eA interface for RR. After all he asked me to change the interface.

Success!
