Design with 2.8 inch IPS Capacitive Touch Screen SPI Display Module in Cirkit DesignerThe 2.8 inch IPS Capacitive Touch Screen SPI Display Module, manufactured by Hosyond with the part ID ILI9341V, is a high-quality display module featuring an In-Plane Switching (IPS) screen. This module offers capacitive touch functionality, allowing for intuitive user interaction. The display communicates using the Serial Peripheral Interface (SPI) protocol, which is widely used in embedded systems for its simplicity and efficiency. Common applications include handheld devices, touch-based control panels, and interactive projects that require a compact and reliable display solution.
This circuit features an ESP32-C6 microcontroller interfaced with a China ST7735S 160x128 TFT display. The ESP32-C6 controls the display via SPI communication, providing power, ground, and control signals to render graphics and text on the screen.

To use the display module in a circuit:
#include <SPI.h>
#include <Adafruit_GFX.h>
#include <Adafruit_ILI9341.h>
// Pin definitions for the Arduino UNO
#define TFT_CS 10
#define TFT_RST 9
#define TFT_DC 8
// Initialize the display
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST);
void setup() {
// Start the serial communication
Serial.begin(9600);
// Initialize the display
tft.begin();
// Set the rotation of the display
tft.setRotation(1);
// Fill the screen with black color
tft.fillScreen(ILI9341_BLACK);
}
void loop() {
// Check for touch events and handle them
// ...
}
Ensure you have installed the Adafruit_GFX and Adafruit_ILI9341 libraries before uploading this code to your Arduino UNO.
Q: Can I use this display with a 5V microcontroller? A: Yes, the display is 5V tolerant, but it is recommended to use a level shifter for optimal performance.
Q: How do I adjust the brightness of the backlight? A: You can adjust the brightness by applying a PWM signal to the LED pin.
Q: What should I do if the display works but the touch does not? A: Check the touch SPI connections and ensure that the touch controller library is correctly included and initialized in your code.
