 * \file main.ino
 * \brief Main program for MT-07 CAN Bus Interface.
 *
 * \details 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.
