I have a breadboard and wires an everything, so i cant wait to test it out! It will then wake up as soon as it detects more iBus traffic, like you unlocking the car.īut I am ready to start put the ibus adapter together as soon as the rest arrives.
NAVCODER E39 CODE
This allows my library code to shutdown the entire device when it detects the iBus has been quiet for a certain period of time. It's also worth powering the Arduino from the 5v regulator built into the TH3122 (Max 100mA). It even has a multi function steering wheel emulator built in. This (and the Resler interface) will allow you to properly bench test, without having to take everything out to the car for testing. If you haven't already, it's worth registering Navcoder (20 Euros), to be able to send messages on the iBus. You won't get any communication without this. It shouldn't make any difference when connected to the car (it's already pulled up), but for bench testing, you'll need to pull the iBus line up to 12v (car battery voltage) with a 1K resistor. I originally wrote the library code, but the Curious Ninja site is run and maintained by someone else. You should be able to use the library and example code from the Curious Ninja site to do this. Thanks for the link, I have already read alot in this thread, interesting readings there.
NAVCODER E39 BLUETOOTH
When the "ibus device" is made and connected, all that remains is the code to make the arduino talk to the car, and set pins to HIGH when it sees the button on the steerinwheel getting pressed.Īnd this would again trigger the skip input on the bluetooth module. This is currently what im looking into, while waiting on the rest of the parts. But ideally i need to find a way to supply 3.3 volts, controlled by the arduino. I meassured the output voltage from the pin of the arduino, and it supplied only around 2 volts. The pin on the bluetooth module supplies 3.3 volts, and when this is connected to the skip pin, it skip tracks. This made it skip tracks in google play, so this part works. I wrote a simple scetch witch sends a puls every 6 seconds, on one pin that i connect to the "skip" pin on the bluetooth module. Exept the bluetooth module, witch i have tested, and connected to the arduino for testing. Im still waiting for some parts before i can put it together though, so at the moment nothing is up and running. Regarding the items im using, i use the schematics from this page, and i have bought the parts to put this together. Searched for "th3122 arduino" and found some interesting reading that i have to dig into. I probably should start to learn from the bottom, i agree. Hope you would share your experience and tell me if this would even be possible for me to make? So it irritates me that i know so little. So my big question is, is this something i can be able to make my selfe with my limited knowlage?Īnd would the scetch be long and complicated to make it listen on the ibus via the ibus device?Īfter i started fiddeling with the arduino it really is a cool thing, and probably has SO many cool things i could make. My father works with a guy that know this, so he might be able to help but i won't rely my project on him. My brother might be able to help littlebit, but its a few years since he used this thing. But thats about it with my knowlage of this. But the code is aleready made so that part isnt difficult.īut from knowing zero nada about this, i am now able to write a scetch that makes the led blink, and i have made it send an SOS signal. My brother had a arduino kit with leds and stuff that i have used and made most of the tasks in the book, with sucsess. I forgot to mention that i have a Reslers Ibus interface, and i have used navcoder to obtain the telegrams from the buttons.īut, my biggest problem is that i have no knowlage of using and programming the arduino. That will probably be no problem as it wasnt that hard. Will try to make this thing when the parts arrive. So i have bought the parts needed, included a TH3122.4 chip. I have found a scetch of a ibus device used with a arduiono at a site called curious ninja, a lot of interesting information. The thought was to use an arduino UNO (witch I have bought and played a bit with), make a Ibus "device" to make the arduino listen on the ibus, use a simple bluetooth module witch has the capability to skip songs over bluetooth, and make the arduino cotrol the buttons on this with simply ground (i think) the connections for the buttons witch then will make it skip. I have an idea of making a simple interface that makes me control (skip songs) on my steering wheel controls in my Bmw E39 03 model, over bluetooth.
