ESP32RET

Reverse Engineering Tool running on EVTV ESP32Due Hardware

A fork of the M2RET project, itself a fork of the GVRET project.

Requirements:

You will need the following to be able to compile the run this project:

• Arduino IDE Tested on 1.8.4
• Arduino-ESP32 - Allows for programming the ESP32 with the Arduino IDE
• esp32_can - A unified CAN library that supports the built-in CAN plus MCP2515 and MCP2517FD

All libraries belong in %USERPROFILE%\Documents\Arduino\hardware\esp32\libraries (Windows) or ~/Arduino/hardware/esp32/libraries (Linux/Mac).

The canbus is supposed to be terminated on both ends of the bus. This should not be a problem as this firmware will be used to reverse engineer existing buses. However, do note that CAN buses should have a resistance from CAN_H to CAN_L of 60 ohms. This is affected by placing a 120 ohm resistor on both sides of the bus. If the bus resistance is not fairly close to 60 ohms then you may run into trouble.

The firmware is a work in progress. What works:

• CAN0 and CAN1 are operational
• EEPROM can be used to save settings between start ups
• Text console is active (configuration and CAN capture display)
• Can connect as a GVRET device with SavvyCAN
• LAWICEL support (somewhat tested. Still experimental)

What does not work:

• Digital and Analog I/O
