NAVCODER 20 PIN BMW CABLE INSTALL
In the radio housing, I can install a neat single IR LED for control of the radio.Ĭool. In this scenario, only remains to program the Arduino to interface between the car (I-bus), RasPi, display opening sequence (Z4 and X3), and display itself (brightness, contrast, input.) which could be done via IR, much like AJLElectronics' project.īy "talk IR" I mean exactly what you refer to. It also comes with an HDMI input, so makes things easier, signal wise. Same dimensions, but twice the resolution. Allegedly, there's a "drop-in" replacement for the display, on Ali ( link). Second idea is probably easier to achieve, but not my first choice. I have another schematic for achieving SoG (which I have to trace on one of my backup drives). This would avoid the use of the HDMI converter, and possibly eliminate one potential failure point. One is very similar to the approach you've mentioned, with the exception of bit-bashing the VGA signal out of the RasPi's GPIO ( Gert VGA). I mean there are some projects on github for p-bus or m-bus cd changer. The project is going to begin once I have cleared the last two off the bench! The Alpine display data connector looked useful, but again no information of pinout or signals seems to be available. Writing to the display isn't going to happen either because the status data again comes from the radio. I haven't been able to see that handshaking going on though with Navcoder, not sure why. If it doesn't respond, the system shuts down with "No Radio" displayed. The main problem that I see is in "ACKS" because the original radio will not be there and the controller polls it regularly to see if it is still awake. The 'bike has its power and I-Bus brought out on a 3 pin DIN socket for easy interfacing, although I do have a control panel and handlebar switch lash up I can use for basic testing. I have three TH3122 in stock (bought at great expense!) with one mounted onto a DIP converter ready to use. Now the idea is to intercept the I-Bus and use that via an Arduino Nano to "talk IR" to the radio. With that I have been able to pull off the control codes including the ones that I don't think exist via data. I can't find any information on it, so bought an Alpine IR remote. The intention is to use an Alpine CDE-193BT which is slightly more complicated because it uses digital data bursts for control, rather than resistance variations. I had been talking to a manufacturer about adding the codes to their modules, but that is at least on hold now.
NAVCODER 20 PIN BMW CABLE CODE
Yes I have been doing things with it, that's how I know about the code differences.
I wonder if R1200RT protocol is the same. I'm sure you've found out, but in case you haven't, Navcoder can sniff/simulate K1200 comms too.
