![]() However I found a number of interesting libraries with examples that can help beginners understand the working of this display at I have shown how to download and use these resources in a video at the end of this tutorial.įrom the above link you can get LCDWIKI_GUI.h, LCDWIKI_SPI.h and LCDWIKI_TOUCH.h libraries which are important for controlling the 2.4″ TFT LCD touch screen using ILI9341 drivers. In case you don’t have such a conversion module you can just use some 10K resistors as shown in the schematic below.Ĭode for running the ILI9314 TFT Display.Ī number of libraries have been developed to ease the use of this 2.4″ TFT LCD touch screen display with Arduino. This problem can be overcome by connecting the Arduino and the display module through an external level conversion module, so that The 5V high level of the Arduino output is converted to 3.3V by the level conversion module and then input to the display module. However this display module is not 5V tolerant. The SPI module’s pin can only input a 3.3V high level, while the Arduino output has a high level of 5V. For this we only connect the first nine pins of the display. Lets first use the display as a regular TFT display without touch function. You can buy this display using the link below: Interfacing the 2.4 ” TFT display with Arduino T_IRQ :Touch screen interrupt signal, low level when touch is detected.T_CS : Touch screen chip select signal, low level enable.MISO: SPI bus read data signal Touch screen signal line.LED: Backlight control, high level lighting.DC: LCD register / data selection signal, high level: register, low level: data.RESET: LCD reset signal, low level reset.CS: LCD chip select signal, low level enable. ![]()
