You can directly push the LCD screen on top of the Arduino Uno and it will perfectly match with the pins and slid in through. The 2.4” TFT LCD screen is a perfect Arduino Shield. To prevent this I added some delays and the X and Y analog value is read repeatedly and touch is approved only if values do not differ a lot. The touchscreen I tested sometimes wrongly detects a touch, outside of the touched point. We read analog values so values should be in the range 0-1023 for the 8-bit controller, but the touchscreen I tested returns 110-820(min-max). You should notice “Library added to your Libraries” on the bottom-left corner of Arduino, if successful.

#TOUCHSCREEN TFT ARDUINO UNO PINOUT INSTALL#
To install this library, you can simply click on the link above which will take you to a Github page. Note: It is very important for you to install this library in your Arduino IDE for this program to compile without any error. We are using the SPFD5408 Library this is a modified library of Adafruit and can work seamlessly with our LCD TFT Module. To read a position of the touch, use the calibration example program after installing the required libraries for hardware from here. 09h - Read Display Status) set RD from HIGH to LOW, so ILI9341 outputs data until RD returns HIGH.Ĭalibrating the TFT LCD Screen for Touch Screen: To read a byte from ILI9341 after sending a read command (e.g. CS pin has to be LOW during the communication, WR rising from LOW to HIGH tells ILI9341 to read byte on data pins.ILI9341 interprets input byte as a command (if RS=0) or as data/parameter (RS=1). It drives the display and has nothing to do with the touchscreen (Although the shield connects some pins of ILI9341 together with pins of the touchscreen).įirst, you have to send a command to ILI9341 and then write or read data/parameters. ILI9341 is integrated inside the display. ILI9341's RESET goes to Arduino analog pin A4. The shield connects ILI9341's data pins 0-7 to Arduino's digital pins 2-8 (allowing parallel communication, not SPI.
