# M5IsobusVT
[](https://joinup.ec.europa.eu/collection/eupl/eupl-text-eupl-12)
Implementation of an ISOBUS-VT on the **M5-Stack core2** module.
...maybe the smallest ISOBUS-VT of the world !
 
Most of the code is from my College Reinhard Hübner (thank you very much for this great work). I only rearange some part of the code to compile it with PlatformIO and remove some unused code.
See download and installation for details.
## Download and Installation
* To download click the DOWNLOAD ZIP button, rename the uncompressed folder 'M5IsobusVT'
...or clone it with git.
* the project contains in the 'lib'-directory all references to used libs. There is no need to add external libs.
* copy the 'SD_CARD' folder to the root directory of a SD-card and put it into the M5-Module
## Software and Hardware CAN adaption
The actual Implementation use the "M5-Stack core-2" Hardware (we need the PSRAM,so the old "M5-Stack-core" does not work).
For the future we plan to adopt it to hardware with other (higher resolution) TFT-Displays. But even for this we need a ESP-32 (or ESP32-S3!?) with PSRAM.
For the CAN communication we use the internal ESP32 CAN controller and map it to GPIO36 (Rx) and GPIO26(Tx). Only for the hardware adaption a external CAN-Transmitter was used. The D-SUB connecter is wired according to a common used pinning of USB-CAN adapter.
 
## Remark
* Don't add M5Stack as external lib, because there are some changes to the original lib. Changes from the original code are marked with 'huebner'
* We have changed the ESP32-Arduino default stack size, so if you compile it outside from Platform-IO change the stack size in the arduino startup code.
**!! DONT USE IN IN A REAL TRACTOR - ONLY FOR EDUCATION AND TRAINING IN LAB !!**
### PlatformIO and Arduino-IDE
Projekt was build and testet with PlatformIO, for Arduino-IDE we will add in future some extra infos.
