3.5" 480×320 IPS Capacitive Touch Screen

1. Example Code for Arduino - basicTest

This is a basic display example, including drawing points, lines, circles, rectangles, etc.

2. Example Code for Arduino - gettureFont

This is a UI control demo—a numeric keypad. First, click the text box to display the cursor, then click the numbers to show the corresponding digits in the text box. The "x" in the bottom right corner of the keypad is used to delete content in the text box.

3. Example Code for Arduino - UI gesture

This is a gesture reading example. Perform operations in the gesture area: click, double click, long press, upwards slide, down slide, left slide, right slide.

. Interface Description

2.54 Pin interface description

Pin No.	Name	Function Description
1	VCC	Positive Power Supply
2	GND	Negative Power Supply
3	SCLK	Clock
4	MOSI	Data (Host Transmits, Slave Receives)
5	MISO	Data (Host Receives, Slave Transmits)
6	SCR_CS	Screen Chip Select
7	RST	Reset
8	DC	Data/Command
9	BLK	Backlight. The backlight has a default setting, so the user can turn on the screen without connecting the backlight pin; in addition, when the backlight pin is connected, inputting a high level (1) sets the backlight brightness to maximum, and inputting a low level (0) turns off the backlight.
10	SCL	Touch Clock
11	SDA	Touch Data
12	INT	Touch Interrupt
13	SD_CS	SD Card Chip Select
14	TP_R	Touch Reset

GDI interface description

This is a DFRobot-specific GDI display interface. Connect the screen using an 18-pin FPC cable for more convenient connection.
When connecting the screen with an FPC cable, simply configure the corresponding pin numbers according to the GDL demo.

The pin mapping is as follows:

FPC PINS	Description
VCC	3V3
LCD_BL	Backlight
GND	GND
SCLK	SPI Clock
MOSI	Host Output, Slave Input
MISO	Host Input, Slave Output
LCD_DC	Data/Command
