This part contains to the "drivebox" project.
I can proudly announce that I am already collecting new ideas for a new development of the drivebox.
Some key points of the upcomming device:
- 4x sensor inputs (analogue 5V, e.g. boost pressure sensor)
- 8x switching outputs (4x GND, 4x 12V)
- Output for smart LEDs (WS2812/SK6812, e.g. ambient lighting, shift light)
- I2C display output (‘FIS lines’ on external display, passenger display for speed or rpm, measured value output)
- I2C sensor (gyro sensor for G-force display)
Early 2023
Updated Hardware (2024)
Here are the update instructions for the device.
Info: default password of the access point "123455678".
- Download the latest firmware.bin from release page.
- Go to the OTA update page on your device or enter the url directly (http://192.168.4.1/update)
- Selecte Firmware and upload the firmware file
- Wait for device to reboot
- You may have to reconnect to the devices WiFi
//tbd -> there is no complete manual yet.
CAN bus termination on CAN1_TERM or CAN2_TERM may necessary. Typically both ends of a CAN bus are terminated. When using CAN1 on older Cars that haven't got a comfort CAN installed, you maybe connect only drivebox to a head unit. Then the CAN1_TERM is necessary to be switched on. If you connect CAN2 to an existing motor CAN you don't have to enable CAN2_TERM.
CAN1 is designed to be VAG like comfort CAN. Bitrate is set to 100 kBit/s.
CAN2 is designed to be VAG like motor CAN. Bitrate is set to 500 kBit/s.
Connect the three Pins of the drivebox "GND", "LIN", "VBAT" directly to your steering wheel. If you have a steering wheel that doesn't go into sleep mode, you could connect f.e. ignition voltage to the steering wheel.
