# ESP32-S3 GT Racing Dash

This dashboard is heavily inspired in two projects. [ESP-SimHub-ESP32S3-SCREEN](https://github.com/eCrowneEng/ESP-SimHub-ESP32S3-SCREEN) and [Lovely Dashboard](https://github.com/Lovely-Sim-Racing/lovely-dashboard).

This project attempts to simplify what ESP-SimHub-ESP32S3-SCREEN does by removing all the SimHub-Arduino interactions and extra functionalities (like controller, NeoPixels, 16x2 LCD, etc.) by using SimHub's **Custom Serial Device** functionality. Where a Custom Protocol is defined and sent over USB-Serial to the outside world.

On the ESP Side there are some key decisions:
* ESP IDF is used (no Arduino, no PlatformIO), all these include several extra dependencies and/or remove control from the user, although they favor simplicity on the coding side.
* For graphics LVGL is added as a dependency and it's integrated to the project for graphics rendering
* The UI is designed using EEZ-Sudio, an open source drag&drop IDE for GUIs. And integrated seamlessly by adding it as an extra component to the project.

Lastly, the UI is heavily inspired in Lovely Dashboard. No assets were stolen from it, it only came as an inspiration for data/object placement and colors.

## How to use

* Clone the repository using
  git clone
* Open the cloned repository folder with VSCode

### Hardware Required

* An ESP development board, which supports the RGB LCD peripheral and Touch (if you want it)
* A general RGB panel, 16/24 bit-width, with HSYNC, VSYNC and DE signal
* A capacitive/resistive touch panel (if needed)
* An USB cable for power supply/programming/serial Comms

### Software Required
* VSCode
* ESP-IDF Extension
* You might or might not need to have also Git and Python installed (I believe this comes bundled with ESP-IDF Extension, if not, please refer to ESP-IDF install instructions)
* SimHub
* Your SIM of choice, supported by SimHub

### Build and Flash

*IMPORTANT*: Before building, if you don't have a GT911 touch panel or wish to not use touch functionality, disable it by commenting #define USE_TOUCH_PANEL in main.c before continuing to prevent the screen crashing at boot.

Run `idf.py -p PORT build flash monitor` to build, flash and monitor the project. A scatter chart will show up on the LCD as expected.

The first time you run `idf.py` for the example will cost extra time as the build system needs to address the component dependencies and downloads the missing components from the ESP Component Registry into `managed_components` folder.

(To exit the serial monitor, type ``Ctrl-]``.)

See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.

Alternatively make sure to configure ESP-IDF on the VSCode bottom bar with your ESP Chip, UART/JTAG uploading measure, and your ESP32 COM port on your PC. Then press the build flash and monitor icon (flame).

### Example Output

If everything goes right, you should see this on your ESP IDF Monitor terminal.

You should also be able to see the following image on your LCD:

### Connecting it to SimHub

* Ensure your game is detected by SimHub and it's configured
* If not done already, enable Custom Serial Devices in SimHub by clicking on the following button in the lower left corner
  <img width="256" height="93" alt="image" src="https://github.com/user-attachments/assets/7ec2bb09-401e-4285-8141-72bc9b49c84e" />
* Once that's done, copy the contents of "SHCustomProtocol.txt" bundled in this repository to the Update messages section in Custom Serial Devices in SimHub by clicking on Edit
  <img width="1346" height="401" alt="image" src="https://github.com/user-attachments/assets/43917f63-ecd9-4d82-a73b-9cb32e49943f" />
* After that, make sure to enable the update messages, select the frequency in which the messages will go out to the ESP. Configure your comm ports acccordingly and enable the communication.
