This Arduino sketch provides a basic simulation of a Speeduino ECU serial interface, generating and transmitting simulated real-time engine status data. The simulation includes a simplified engine model and supports the 'A' command for real-time data. This solution could be useful when quickly testing logging, gauge or other Speeduino ECU implementations without the ECU itself. Hopefully more detailed serial interface simulation will be added in future releases.

• Prerequisites
• Installation
• Usage
• Customization
• License

Make sure you have the following tools installed before running the simulator:

• Arduino IDE

1. Clone the repository
2. Open the speeduino-serial-sim.ino file using the Arduino IDE.
3. Connect your Arduino board to your computer.
4. Select the appropriate board and port in the Arduino IDE.
5. Upload the sketch to your Arduino board.

1. Upload the sketch to your Arduino board.
2. Open the Arduino Serial Monitor (or any other serial communication tool) to view the simulated engine data.
3. The sketch listens for the 'A' command, and upon receiving it, responds with simulated real-time engine data.

Feel free to customize the simulation parameters and add more features according to your needs. The key parts of the code for customization are:

• The EngineStatus struct: Modify this structure to include or exclude specific engine parameters.
• The EngineSimulation.cpp class: Adjust the simulation logic to better match your requirements.
• The baud rate: You can change the baud rate by modifying the SERIAL_BAUD_RATE constant.

This simulator is a basic implementation and just barely been tested for compatibility with a real Speeduino ECU system. It currently supports only the 'A' command for basic real-time data.

Can be used together with speeduino-to-mqtt project to generate test data and golf86-info to display in on LED matrix display. This was the original use case that this was created for: to test pushing parameters to MQTT and display without physical ECU.
