In case of using the Raspberry in the car, there was a topic about the powersuply and long bootup time. Inspired by other Interfaces like pibus, Intravee, eLight, modLight i decided to develop a specific shield. After some time and some requestes the standalone Modul was born.
- AVR Mode
- Raspberry Shield or standalone Modul with GUI for OEM System
- Using OSMC or LibreElec with the Addon IBusCommunicator for Kodi
- IBus Interface Mode
- you can use this DIY Modul as usual USB IBus-Interface also (e.g. for Android Radio Headunits with I-BUS App)
- upload the other Firmware to get it working
- CD-Changer Emulation
- Welcome Message on E39 IKE High
- Welcome/Leaving Light depended by Brightness
- Lightsequenzes for: *
- Welcome
- Leaving
- Follow Home
- Flash2Pass
- use google Sheet to define your light sequenzes AVR-IBus Light Sequenzes
- Mirror Folding
- unfold/fold for Welcome/Leaving
- fold Mirrors by Ingintion Position Off *
- unfold Mirrors by Ingintion Position On *
- unfold Mirrors by double press Open on Remote *
- fold Mirrors by double press Close on Remote *
- fold Mirrors by hold Close on Remote *
- unfold/fold by Key insert or remove of Ignition Lock *
- unfold Mirrors by Door opening *
- Flash to Pass
- One Touch direction signal
- Fog Corner Lights for E39
- Day Running Light
- Aux-Heating control by Remote Key
- Brake Force Display (Coding of IKE requiered) *
- Convertible Roof Control for E46 by Remote Key
- Auto-Relock for Central Lock after Unlock and no door was opened
- Auto-Zoom for Navigation Map by Speed
- PDC Display at E39 IKE High *
- OBC-Value Display at E39 IKE High [Coolanttemp, Speed, Oiltemp or Voltage] (under construction)
- RearCam power control and enable Video input at TV-Modul
- Configuration Options:
- Menu for Bordscreen
- Menu for MID (under construction) *
- Serial-Protocol (see Describtion below)
- Cross platform Configuraton Tool (Windows, Linux, Mac)
*only V2
- V1 RaspPi - Shield for Raspberry Pi
- V2 RaspPi - Shield for Raspberry Pi
- V2 Basic - Standalone Modul
- finish Android App for Configuration
- Extension for Bluetooth A2DP Audio Streaming (only for Basic)
- Request RLS for Welcome/Leaving
- may modify RCam-Control for other Solutions (e.g. Coolant Thermostat)
- Features like LinBusBox/IBusBox
- Feature Requests:
- Move down Mirror for Parking
- CAN-Bus Extension
-
V1.x
-
V2.x
- V1.x
For opening GUI of OEM BMW Infotaimentsystem:
- do Double press MENU-Key of Bordscreen
- do Double press BC-Key of MID
