HQCT Module (new thread following HU RDS/RDBS)
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
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?
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.
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
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?
Can Datalex or Putput provide a driver to use the HQCT -e in AUX mode and when the FE either [CF or RR] goes to RADIO it goes to the TUNER and then when the FE closes the RADIO it reverts back to AUX?
I do have a CPCTuner app that I couldnt get working properly, so with CF3 out was hoping there was further developement with HQCT -e & HQCT -eA
I really need a way to solve my audio output problem and I believe this will fix it.
New Car PC Build list in progress
I recently bought one HQTC.
I don't have car PC. I would like to control it through a microcontroller by writing my own application.How can I control HQTC through a microcontroller.
What is your HQTC.dll does. Can you explain me how can I control the tuner without using HQTC.dll. I am a pure C progrmmer.
