HQCT software development - Page 12

Hi Putput,

Just to report back, I was getting a similar error to the one that BES reported using a HQCT-i. On your latest version i got the error "CPCtuner could not connect to HQCT module". however your last version 1.1.52 works fine no problems.

if you want me to do some more testing let me know.

Luc,

In your latest HQCT DLL (which I belive is used by Flux Media for Centrafuse) you refer to the "Select the sound source for the audio output, 0=Tuner, 1=CD, 2=Phone, 3=Navigation"

Could you confirm that the "1=CD" is the "Aux 1 I/P" and the "Aux2 I/P" is the "2=Phone" on the HQCt-eA please ?

Regards Glitch

Hi Glitch,

This is part of the routine that sends the soundsource to the module:

Code:

procedure THQCTuner.SetSoundSource(TheSoundSource : TSoundSource);
begin
   case TheSoundSource of
      TunerSrc:
         begin
         end;
      CDSrc:
         begin
         end;
      AUXSrc:
         begin
         end;
      PhoneSrc:
         begin
         end;
      NaviSrc:
         begin
         end;
   end;
end;

TunerSrc starts at 0, so you can see that CD = 1, AUX = 2, ...

Luc,

Sorry I did not word my original question ciorrectly as I am now very confused?

What I'm trying to find out is that in your CPCTuner program you have the sound souces "Tuner, CD, Navigator & Phone" labelled. However on the HQCT-eA there is no physical "CD" RCA I/P only "Aux1" & "Aux2" according to the wiring diagrams.

So in CPCTuner if "CD" is selected as the sound source is this "Aux1 or Aux2"?

What I am trying to do is write a small program using VB/Delphi to switch the sound source to "Aux1", thats all I want it to do.

However having not done any programming for over 27 years and even then that was in BASIC, I am trying to learn VB/Delphi and give it a go.

I'm having to do this as Centerfuse does not support the HQCT-eA properly and enable sound source switching.

regards Glitch

Hi Glitch,

Sorry for confusing you, you are correct about the difference between my code and what is in CPCTuner. I've checked the code from CPCTuner and it appears that my info is not complete.
In CPCTuner you cannot select the AUX input, this is still something I need to change/add, however you can select it using the DLL and I believe that this is what you want to do. Here's how:
Call HQCTSetSoundSource with following parameter:
0 for Tuner source
1 for CD source
2 for Phone source
3 for Navigation source
4 for AUX source
Hopefully this can help you out.

I know that eA support in Centrafuse is not entirely finished, I'm sure David & Co are working on it but IMHO it's not an easy thing to add. Centrafuse sees the HQCT software as a radio plugin that is activated when the user wants to play radio, once you switch source in Centrafuse it needs to change the in-output in HQCT to get sound when the eA is used and also has to set different volume levels to the correct output. As a temporary solution you could write a little application in VB to set the correct in/out, it's possible that more then 1 application uses the DLL to control an HQCT module at the same time.
Let me know if your solution works, perhaps there are others who want to you use it as well. You can post it in here if you like.

Success!

Quick Question - I want to take the output from the PC (stereo jack) and plug this into the HQCT aux via a jack to RCA cable and then use the F/R-L&R line out to feed into the AMP as my main audio output source.

Now will i get sound all the time when not using the radio via AUX and then when selecting RADIO, the AUX is off to hear radio, then when radio off, to hear AUX?

How can I select this option via RR/Skin as I've notice when radio launches, i see the HQCT app and I can choose CD which give me sound through AUX, but so far I have to make sure CD/AUX is selected.

Is this right or an I doing something wrong?

(This is the only way I can achieve sound at this stage - do to HW limitations)

I hope I made sense - I posted this in the other HQCT thread, which maybe the wrong one

The above got answered under this thread for those interested in doing similar

I've got a RCA cable connected from my pc stereo jack to my HQCT-eA aux audio input.

Problem is I can't get any sound out of the HQCT. However if I run CPCTuner then run roadrunner and select the radio etc, I'm able to listen to the radio.
RRHQCT runs in the background at this stage. The radio doesn't work unless I first run CPCTuner though. I select CD on the RRHQCT but nothing.

What I am doing wrong?

Hi almond1303,

Did you resolve your problem? I'm having the same problem and have gone through this thread (and others), but can't find an answer. With a lot of fiddling I can get the radio to work through RRHQCT.exe and then I can control it in Road Runner (haven't installed Ride Runner yet), but it takes a couple of minutes to get to that point from starting the car. I'm not getting any sound output from the PC at all and the PC is connected to the HQCT-eA from the PC speaker out to the HQCT-eA Aux1.

What am I missing? Luc has a DLL, but I don't know what it is for or how to use it. There are lots of settings in RRHQCT.exe, but I've not been able to find any documentation that explains how to use it.

I've managed to design, build and install the rest of the car PC by finding answers in this forum, but this one component has me baffled.

Hi Putput,
Hey fantastic work on the Hqct i you truly are a genuis love the stup

I am having problems with my Hqct I displaying USB error cant find device code
i believe this has been mentioned on several occasions in the forum but with no response are you any closer to resolving this problem

everytime my customers shut down there car pc then reboot it display this error when they try to open cpctuner exe
the only way to get the system back up again is to unplug the 3 pin molex plug for the power on the board and replug then it hot plugs and finds it
i would appreciate if you could try to sought this out please i have 15 units all doing the same thing
and my customers are not very happy
if any one has the answer greatly apreciate a fix
thanks
in advance

Any News on this??

I've now got my HQCT-eA working, but I'm still having problems with the software. I have tried RRHQCT and PutPut's CPCtuner, but there are problems with each:

CPCtuner by Luc works nicely for the radio most of the time, but I always have to start it twice - I'm seeing the same problem that Wazza has reported, the software cannot see HQCT when it first starts. My second problem with this is that I can't select the PC as an input. I found that I should be connecting the PC sound card to Aux2, but I don't see that as a source in CPCtuner. My third problem is trivial, but still anoying - the default bass setting is a bit high for my liking, but when I try to adjust it down, I get an error: out of range and the program terminates. I'm running it in stand alone mode, not through RR.

With RRHQCT, the problem I have is saving settings. Alex of Datalex told me how to adjust the settings to use it with RR, but it always goes back to defaults whenever I restart. I suspect that the settings should be saved to the HQCT-eA hardware, rather than in software, but the wiring diagram (by Luc) shows both red wires fed from ignition and no permanent feed, so the unit is powered off every time i stop the car - is that right? Alex sent me a copy of RRHQCT that is different to the one supplied with RR; I think it is specifically for the eA model and I have to spend several minutes adjusting the settings before I can start driving.

There must be people out there with working installations of HQCT-eA. How are other people implementing it?
