esp32-usb-monitor

This project implements a GUD (Graphics USB Display) driver for the ESP32-S3 microcontroller from Espressif. The code has been ported from the original repository notro/gud-pico.

Getting Started

Follow these steps to set up and use the code:

  1. Install ESP-IDF v5.1 by referring to the official ESP-IDF documentation.

  2. Optionally, you can install Visual Studio Code (VSCode) for a more convenient development experience.

  3. Clone or download this repository to your local machine.

  4. Set up the Environment Variables for ESP-IDF.

  5. Set the IDF target to ESP32-S3 by running the following command:

    idf.py set-target esp32s3

  6. Build the code using the following command:

    idf.py build

  7. Flash the program to your ESP32-S3:

    idf.py flash

  8. Connect the ESP32-S3 to an ili9340-based TFT LCD display using the provided pinout, you can use ESP32-S3 DevKitC 1:

TFT LCD Connection ESP32-S3 GPIO
SCK GPIO 7
SDI (MOSI) GPIO 6
CS GPIO 11
DC GPIO 12
Reset GPIO 47
Backlight GPIO 48
USB D- GPIO 19
USB D+ GPIO 20
  1. Connect the ESP32-S3 to a PC's USB port with a GUD driver using GPIO 19 (D-) and GPIO 20 (D+). The ESP32-S3 should show up as a GUD USB display.
