Hardware Connection

Here is the basic wiring for the ILI9225 TFT screen with the development board:

• VCC: Connect to the Arduino's 5V (or according to your screen's specifications, some may require 3.3V).
• GND: Connect to the Arduino's GND.
• CS (or TFT_CS): Chip select, connect to a digital pin on the Arduino, such as pin 10.
• RESET (or TFT_RST): Reset, connect to a digital pin on the Arduino, such as pin 9.
• RS/DC (or TFT_RS): Command/data control, connect to a digital pin on the Arduino, such as pin 8.
• SDI/MOSI (or TFT_MOSI): Master out, slave in, connect to the Arduino's pin 11 (for UNO).
• SCK (or TFT_SCK): Clock, connect to the Arduino's pin 13 (for UNO).
• LED: Backlight control, can be connected directly to the Arduino's 3.3V or 5V, with a resistor for current limiting, or connected to a PWM output to control brightness.
• SDO/MISO (or TFT_MISO): Master in, slave out; if you need to read data from the TFT, this line needs to be connected to the Arduino's pin 12 (for UNO).

Usage Method

Installing Library Files (skip this step if already installed)

1. Open the Arduino IDE.
2. Go to “Tools” > “Manage Libraries…”.
3. Install the TFT_22_ILI9225 library via “Manage Libraries” (search for TFT_22_ILI9225 in Tools > Libraries > Manage Libraries... and install it).
