@ Automatic external scanner collision detection.

Principle

Basiclly, the project is a small OBDII scanner that requesting information from DME and EGS. It reads data from D-Bus then write display string to I-Bus. There are 4 wires needed to connect to wire harness of IKE (12V / GND / D-BUS / I-BUS)

Hardware

Base on STM32F103C8T6 (20k RAM / 64k FLASH)

Software

All bugs are made by my self @@
