The best way to calibrate is to use the calibration example program (comes with library) or use the serial monitor to detect your error. These calibrations results will not be similar for all boards and hence you are left on your own to do this. A LCD screen without calibration might work unlikely, for instance you might touch at one place and the TFT might respond for a touch at some other place. If you planning to use the touch screen function of your TFT LCD module, then you have to calibrate it to make it work properly.

If you are having a cheap clone like mine then it is most probably using the ili9341 driver IC. This detail has to be obtained from the vendor. So, it is very important to know which types of LCD display your are holding in hand. A program which works perfectly for your Adafruit shield might not work the same for Chinese breakout boards. There are many types of TFT modules available in the market starting from the original Adafruit TFT LCD module to cheap Chinese clones. You can also find an SD card slot at the bottom of the module shown above, which can be used to load an SD card with bmp image files, and these images can be displayed in our TFT LCD screen using the Arduino Program.Īnother important thing to note is your Interface IC. A small classification of these pins is given in the table below.Īs you can see the pins can be classified in to four main classifications such as LCD Command Pins, LCD Data Pins, SD Card Pins and Power Pins, We need not know much about the detailed working of these pins since they will be take care by our Arduino Library. Let us take a look at the pinouts of this 2.4” TFT LCD screen module.Īs you can see there are 28 pins which will perfectly fit into any Arduino Uno / Arduino Mega Board. There are various features such as displaying text, font-sizes, bitmaps and even making basic animations on the LCD.Getting to know the TFT LCD Screen Module:īefore we actually dive into the project it is important to know, how this 2.4” TFT LCD Module works and what are the types present in it. Once you have everything wired up fire up the Arduino IDE and load the Adafruit Example Sketch. The BL is the back light for the LCD module and it is a optional connection. That should be everything you need to connect up.
As we are using the Adafruit example to get you up and running connect the Pins as follows, example code to come: Once you have done that you’re all ready to hook up the LCD to the Arduino, we used a small cheap breadboard for this task as the LCD module came with male pins already attached. More information can be found on the Datasheet located here.ĭownload the above libraries and rename the dash ( – ) to an underscore ( _ ) in the folder names so that the Arduino IDE can load the library correctly you’ll know if you haven’t done this as the IDE will show a popup message saying it can’t load the library. Notice that the module only needs 3.3v from the Arduino.
