How to display images on aTFT LCD display?

Here's a concise guide to display images on a TFT LCD:

1. Prepare Image Data (Key Step)

• Microcontrollers can't decode JPG/PNG directly

• Convert images to C array using tools like LCD Image Converter

• Use RGB565 format (2 bytes per pixel) - most common for TFT displays

2. Hardware Setup & Initialization

• Identify interface: SPI (few pins, slower) or Parallel (more pins, faster)

• Use library (e.g., Adafruit_ILI9341 for Arduino) to initialize display

3. Core Code

Key Points:

• Store large images in PROGMEM (Arduino) to save RAM

• For SPI displays, maximize SPI clock speed

• Set correct display rotation to match image orientation

The Process: Convert → Store → Stream pixel data to display
