Detailed Description

Main program for MT-07 CAN Bus Interface.

This program uses the MT07_CANBus library to interact with the CAN bus of a Yamaha MT-07 motorcycle (2014 model). It initializes the CAN bus, decodes incoming messages, and displays the following data in real-time:

• Gear position
• Throttle position sensor (TPS)
• Motor and air temperature
• Speed and RPM

\usage

• Connect the MCP2515 module to the ESP32.
• Wire the CAN bus to the motorcycle.
• Compile and upload the program to the ESP32.
• View the decoded data in the Serial Monitor at 115200 baud.
