Good work Vitalic!

I agree two channel is the way to go.

Could you please provide details of the HDMI switch and a diagram of how you wire up the switch from OEM to Pi please?

Hi All,

I have a pibus 4 with all the cables (I believe) it's been sat in the garage for 2 years as I sold the e46. Open to offers if it is any use to someone?

Thanks,
Arron

This item has been sold, thank you

At PeteAu:

Is there a partlist with the type/name/value of the resistors, coils, diodes etc.? For maintenance. Giuss i grilled Q2 while testing videoswitching.

Already changed the Pi but still get 0.5V output from this pin. Need to know what LPW41 is?

@Baddabing its relative easy to switch between 2 HDMI channels with the right hardware. But it has become a problem to use the reversecam with this setup.

Thats why i will wait until i habe a solution for this too. But now i need some info from Pete as i grilled Q2 on the board while testing (LPW41).

Don't want someone else to crash the board.

Thx. Fixed it. Desoldered one from broken laptop mainboard and resoldered it at Q2. Works again.

I've had a weird issue come up lately: there is a seemingly random rolling or flickering/fuzzy effect when using the pibus. It started when the colours started to get a bit too bright and washed out around the edges, then the random rolling effect starts. The rolling only lasts for a little bit, and if I switch back to the nav screen then back to pibus it goes away for a while. The over-bright flickering/fuzzy effect stays though. Checked all connections, running OSMC and an old version, but all do the same thing. Any ideas what I could check?

So i managed to switch between 2 different HDMI channels automatic. Just like Pibus does but now with new touchscreen instead of oem display. I also managed to switch to reversecam, but some more investigation is needed here, because the green is to high at cam picture. This is because of the sync signal separated from green line.

So right now i use a 2 in 1 HDMI switch. Channel 1 is TV Modul, Channel 2 is Pi. The RGsB signal from TV Modul is converted to HDMI via a separate converterboard. Th sync signal therefor needs to be separated from the green color signal.

At the moment i use 2 relais to switch between the channels. They also react on reversegearsignal and switch to cam.

I'll upload a schematic when the greencolor problem on reverse is fixed.

So no other switches or anything else but oem buttons and control is needed to switch the input automatic.

So i found a way to reduce the extragreen color on reversecam.

On the converterboard you can also setup some things. Clamp st and clamp sp fixed the prolem. So now everything runs super.

Anyone running crankshaft on the pibus? If so do I need to remap the keys of the OEM headunit?

I've been working on mine on and off - probably should get around to updating my guide on the other thread...
You need to remap the keys, which are set using the evdev file. Sudo nano /usr/share/X11/xkb/keycodes/evdev will get you into the file, and replace the existing mapped number with these:
57: replace with 60
55: replace with 59
65: replace with 56

That will take care of the steering wheel controls for next, previous and play/pause. When I get some time I'll keep going with the rest.

Still working on my weird rolling image issue first....

I guess it's a hardware issue with the tv module as it creates the pic from pi input.

The nav creates it's own pic and the tv module is only in bridgemode when nav sends the pic.

And still i guess tv module. Sync problem.

You may try different sdtv modes on config.txt of the pi. But i'm sure it wont help.

Ha! That did it! I tied PAL, no luck, then the Japanese NTSC setting and bingo! No more rolling.

It must be have been when I set my region to Japan to bypass the warning message on startup... I just didn't think it would affect anything else

Anyone got any idea how to enable Right Rotary Controller when in Aux mode. Natively it does nothing - but I am told it can be switched on.
