Esp32-C3 bassed Tiny Game Console

I made keychain sized game console with st7789 display and using esp32-C3 SoC. In this project used part of mostly recycled parts from broken smartwatch and electronics boards.

🛠️ Hardware Checklist

To use this library and run the provided examples, you will need:

• Microcontroller: ESP32-C3 Development Board
• Display: 1.3" ST7789 TFT Display from old broken smartwatch
• Buttons: 3 Tactile Button From old Electronic Boards
• Wiring: Recycled cables
• Switch: Again old electronics boards
• 3D parts: Link https://cults3d.com/en/3d-model/game/diy-tiny-game-console-1-3-st7789-display-esp32-c3

🔌 Pinout & Wiring

By default, the library is configured to use the standard SPI pins of the ESP32-C3. You can customize these pins directly in the setup file to match your project's needs.

Component	ESP32-C3 Pin	:---
TFT MOSI	Default SPI MOSI	GPIO 6
TFT SCLK	Default SPI SCLK	GPIO 4
TFT CS	Defined in User_Setup	-1
TFT DC	Defined in User_Setup	GPIO 8
TFT RST	Defined in User_Setup	GPIO 5
SD Card MISO	Default SPI MISO (Only if using SD!)	-1
Left	One Leg	GPIO 1
Right	One Leg	GPIO 7
Action	One Leg	GPIO 3
Buzzer	Positive Leg	GPIO 0

(Note: Check your specific ESP32-C3 board's pinout diagram for the exact default SPI GPIO numbers).

💻 Arduino Installation & Setup

1. Install the Library

• Download this repository as a .ZIP file from GitHub. https://github.com/derdacavga/DSN-Esp32C3-St7789
• Open your Arduino IDE.
• Go to Sketch > Include Library > Add .ZIP Library and select the downloaded file.

2. Configure the User Setup This is an important step! Just like TFT_eSPI, you must configure the library to work with your specific wiring.

• Navigate to your Arduino libraries folder and open this library's folder.
• Open the User_Setup file.
• Define your specific pins, SPI speed, and color format here.
• ⚠️ SD Card SPI Sharing: If you are using an SD card on the exact same SPI bus as the display, you must uncomment the MISO definition in this file. If you are not using an SD card, leave it commented out.
• Save and close the file.
