Previous versions of this code were based on detecting a new message.Ĭonst int CS_LWAKE = 8 // HIGH enables MCP2025 Txīyte ibusData // assumes max message is 37 bytes This means that detecting a gap signals the end of a message It will only be restarted when the first bit of the next message is detected Having detected the gap Timer2 will be inactive during a long gap. to wait for a new message when there is a long delay between messages. this version is modified to use a Timer2 interrupt to detect gaps to avoid the need this version is the one I posted on Forum modified to use an interrupt. I am not even sure if the Linbus tranceiver wakes up or not. But I dont get any message beside “- IBUS Gap Detect version -” and then a legth to zero. I just modified for my needs, I am using a mega and serial0 to communicate to PC and Serial1 to communicate with MCP2025. I was trying to write my code just to receive but than I swithced on your code that you shared on “Struggling with my BMW IBUS projects. But basicly I connected 12V+ to VBB, both arduino’s and power supply ground to VSS, connected linbus to LIN line, CS to Arduino pin 8 and RX-RX and TX-TX and pin 2 to ibus line. I cannot create the schematics due to issues with KiCAD on win10. Currently it is disabled as there is no ibus message on the line. My head unit is removed from the car and I powered it with an 12V adapter on my desk. This is used to tell if it’s clear to send on the IBUS.įirst I would like talk about my setup. I feed pin 9 (SEN/STA) to one of the Arduino interrupt pins (2 or 3 on the Uno/Nano).

Remember to set the serial port to SERIAL_8E1 for the IBUS. Don’t cross them over as you would normally. As soon as you hit the unlock button, it all fires up, and is running before you get the door open My entire system shuts down after 60 seconds of IBUS inactivity.

As soon as this happens, the Arduino will also power back up. The TH3122 will wake up as soon as it sees any traffic on the IBUS. If you power the Arduino from the built in 5v regulator, you can use this to shut everything down to save power. Drive it high to enable the chip, and drive it low to put the chip to sleep. Pin 2 (EN) goes to a digital output pin on the Arduino.

I was about to order some more myself, and I’m happy to split the shipping cost if you like.

Hi to all member Here is one usefull program with patch and interface I use it and is very good Here is some info from official site NavCoder is a Windows application to reprogram BMW navigation computers and other ibus devices. 2004 BMW 325Ci OEM E46 TELEMATICS CONTROL UNIT TCU MODULE EVEREST IBUS 6947308 (Fits: BMW) Pre-Owned.
