6. Setup and Development Environment

This section outlines the steps to set up your development environment for the ESP32-S3-LCD-2.8 board using Arduino IDE.

6.1 Installing Libraries

To begin development, you need to install the necessary libraries in your Arduino IDE. If you do not have a 'libraries' folder, create one in your Arduino sketchbook directory.

1. Open Arduino IDE preferences and locate the 'Sketchbook location'.
2. Navigate to this location and create a new folder named 'libraries' if it doesn't exist.
3. Copy all required library files into this 'libraries' folder.

6.2 Board Selection and Configuration

Configure the Arduino IDE for the ESP32-S3 board:

1. I Arduino IDE'en skal du gå til Værktøjer > Board > ESP32 Arduino og vælg ESP32S3 Dev Module.
2. Set the 'Flash Mode' to QIO 80MHz.
3. Select 'Flash Size' to 8MB (64Mb).
4. Select 'PSRAM' as OPI PSRAM.
5. Before uploading, ensure you select the correct COM port for your connected board under Værktøjer > Port.

6.3 Uploading Code

After configuring the board and selecting the COM port:

1. Click the 'Upload' button (right arrow icon) in the Arduino IDE to compile and upload your sketch to the board.
2. Monitor the output window for compilation and upload progress.
