Arduino LIN Interface
This Project will use an Arduino to communicate with an HELLA IBS 200X Batteriesensor. The current software version is able to read the most importand parameter from the sensor and print it as a json String over the serial interface or show it on a TFT Display.
The project uses a LIN breakout board from skpan electronics: http://skpang.co.uk/catalog/linbus-breakout-board-p-1417.html, and an ST7735S based 1,8" TFT display.
This project uses ideas and code snipets from: https://github.com/gandrewstone/LIN
The Hardware configuration is as follows:
LINBUS Breakout - skpang.co.uk
| PIN LIN | PIN Arduino Nano |
|---|---|
| GND | GND |
| CS | 2 |
| FAULT | VCC +5V |
| TxD | 3 |
