Only tested in a Volkswagen 2.0 TDI CAGA engine.
The code is mostly based on https://github.com/fkoca5055/obdESP with some changes to check DFP status, provide a WiFi Access Point to change Bluetooth device, PIN, debug viewer...
Please note: as I'm not having so much time to spend on this project the code is quick and dirty.
- ESP32 NodeMCU ESP-32s
- TFT Screen based on ILI9341
- ELM327 Bluetooth
- PCB designed with EAGLE.
- Box to 3d print designed with FreeCAD.
| TFT | ESP32 GPIO |
|---|---|
| TFT_CS | 15 |
| TFT_DC | 4 |
| TFT_MOSI | 23 |
| TFT_SLK | 18 |
| TFT_RST | 2 |
| TFT_LED | -1 |
| TFT_MISO | 19 |
Please change TFT_RST to another GPIO since this the integrated led in NodeMCU ESP-32s.
Remove the screen and make use of the FIS to display DFP information
