Project Description

This is a simple ESP32 project that shows text to the ili9341 lcd display.

Hardware Components

• ESP32 DevKit v1
• Ili9341 LCD Display

Circuit Description

Ili9341 LCD Display is connected to the ESP32 board. RST, D/C, CS, MOSI, MISO, SCK pin of LCD display is connected to esp32 pin 4, 2, 15, 23, 19, 18, respectively. GND pin of LCD display is connected to esp32 pin gnd1. VCC pin of LCD display is connected to esp32 pin 3V3.

Expected Behavior

When the ESP32 powers up, it should:

1. Declare Adafruit_ILI9341 object
2. Begin display and change it to landscape mode
3. Fill the display with black color
4. Display 'Hello World!' at position (0, 0) in white color with text size 2.

Success Criteria

The test is successful when:

1. Text "Hello World!" is successfully printed to the display, with correct position, color, and size.

Notes for Implementation

• Use Arduino.h library for arduino core.
• Use the following libraries: <SPI.h>, <Adafruit_GFX.h>, and <Adafruit_ILI9341.h>.
