Oops, I think I didn't update the TLCDCEmu.properties in the zip file. It should look like

Code:

DebugLevel=3

SerialDriverClass=gnu.io.RXTXCommDriver
SerialPortName=COM1

Plugins=org.tlcdcemu.plugin.gui.GUIPlugin,org.tlcdcemu.plugin.executor.ExecutorPlugin

# org.tlcdcemu.plugin.logical.LogicalPlugin

P.S. If I press a button from 1 to 6 from HU (Disc select) the sound go off and I must change source and return to fake CDC to sound go on

Yes, this is a known issue. I'll fix that.

P.S.2. In car the TLCEmu startup fast, I think there is the Antivirus on Desktop PC that run slow. How remove the GUI Plugin? Is sufficent to remove the

"Plugins=org.tlcdcemu.plugin.gui.GUIPlugin,org.tlc dcemu.plugin.logical.LogicalPlugin"

string in "TLCDCEmu.properties" file?

The line Plugins contains multiple values, separated by a ",". All are optional.

good work! very simple and clear, a question: what is the working differences between your circuit and the Vicne's circuit whit MAX232?

Pippolippi's circuit also has the great advantage of being self-powered, I mean you don't need any extra wires to get the 5V power from the PC.
Finally, it also has one more feature in that it sends to the PC the information whether the head unit is on or off (Remote wire).
The only (small) drawback I can see is that two output wires (RTS & DRT) are used to provide voltage levels to the optocouplers, so you need 2 more wires between the serial port and the adapter (but you already need 4 including remote, so it's not a big deal) and you cannot use those signals for another purpose.
Currently, the Java emulator version you have doesn't set these signals to the correct levels so it won't work as is but I'll change that right now.

Honestly, as soon as I have a bit of time, I think I'm gonna build Pippolippi's interface as well and use that one.

But that's not really necessary (see above post #370)

Since you don't need the isolation you could also use the simpler one (only 2 transistors).

True. I hadn't read your post carefully.

Yes, but I like the idea of optical isolation, and I might change the PC one day and forget about that, so...

Ok, I will try now

Yesterday I've test the system and I've see when HU go OFF while the PC sound it continue to sound, this is a good work for me, because the HU is OFF but the sound is still ON

and this is good for my battery.

But when I power on HU the CDC don't appear in Source List. I must close TLCEmu and re-run.

This is only a report of my test, this isn't a criticism!

Bye and Thanks!

You are right.

I'm going to reset the emulator once the HU is off, so that on HU restart, it begins the handshake again.

PS : So, does the RR control work in the end :-) ?

Hi Vicne,
Today I've some trouble whit my car, I've wrong the PC powed on all night and the battery say Bye bye!
I've try only now, and all OK!!!! Great Vicne! you're the best renault hacker of all history!

hehehehe

The next and previous track work fine, only a detail, when I press next the sound go off for a little time (1/2 sec) after return and then change track, it is only a detail, all ok !

Not good :-(
Don't you have an "intelligent" PSU ?

Yes, that's also known :-) :

I'm waiting for Mox's input to know if he has the same with the connects2. If so, I'm afraid it's a feature of the HU to mute sound as soon as NEXT/PREV is pressed and wait for the CDC to say when it's ready.
The problem is that it's a Fade out/Fade in, so even if I reply immediately that I'm ready, the off/on will be heard :-(
And I fear in this case that it'll be the same with CD changes.
OTOH, maybe we could try to trick the HU by replying with other messages than the original CDC or not acknowledging this command or something. I'll have to fiddle around with that but I want first to be feature-complete.
