3.2 tft lcd shield for arduino mega 2560 datasheet brands
SainSmart 3.2" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and multifunctional module for your project. The Screen include a controller SSD1289, it"s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is ADS7843 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.
SainSmart 3.2 TFT LCD shield works in 3.3V voltage level and you need to use cables to connect with Arduino Mega. And this shield can help you out of the bothers to use other cables. You just need to plug the module to Mega through this shield.
Put the screen(3.2 inch screen schematic) into shield (TFT01-3.2 shield schematic) first, then connect the shield to Arduino, it is quite straight forward.
3)Download and install UTFT ,URTouch ,SdFat,UTFT_Buttons and UTFT_SdRaw library file from following link and copy them into Arduino library folder. ( i.e. D:\arduino ide\Arduino 1.6.9\libraries )
Download the test program (http://www.kookye.com/download/3.2inchscreen/3.2inchtouchscreentest.zip), upzip and open it,then choose the correct board and port.
You will see the code in each sketch: UTFT myGLCD(CTE32_R2, 38, 39, 40, 41).The first value of code refer to the mode of LCD screen. Please write CTE32_R2 or ILI9341_16 if you LCD screen is ILI9341; Please write CTE32 if you LCD screen is SSD1289;
When you use the others LCD screen from the others seller, you could check the PDF instruction in documentation file or open the UTFT.h file to find the correct code.The controller mode could be identifitied by the back mark as the following pictures.
Note: In the project of testing the SD card,please insert the SD card into the slot in back of the 3.2’’ LCD screen. The format of files in SD card must be the FAT32, you need to put the test files(i.e. ICONS.RAW,WAIT4GPS.RAW,SK45) into the SD card root directory.
The TFT shows only a white and static screen with any example of the librery... I´m already change the parameters line with... "UTFT myGLCD(ILI9341_16, 38,39,40,41);" and "UTFT myGLCD(SSD1289, 38,39,40,41);"
I am using visual code with PlatformIO extension, and the library UTFT modified for ILI9341_16, becuase my supplier told me that this was the correct one.
Contact your seller on e-Bay. Ask him what display it is supposed to emulate. Look in the Supported Display file that comes with UTFT/URTouch libraries in the documents folder. See if that display is listed and use its definition in your programs.
- The TFT LCD PCB adapter for Mega is compatible with the Arduino pins, the user can directly connect the TFT LCD PCB - Adapter on the shield and stand on the Arduino board. It can be used with a Mega2560 and LCD screen.
Now, I have bought 3.5" TFT LCD display for my Arduino Mega 2560 R3 to try whether I could run the screen or not, and it is not working now! I am so depressed and angry for these two"s misbehaviors. I have already checked website and a lot of Arduino IDE code examples and libraries such as UTFT.h, UTouch.h, UTFT_MEGA, UTFT_CTE, TFTLCD. I tried these and I can not run my 3.5" screen. Where am I faulty? There is something below the screen shield: www.mcufriend.com and 3.5" TFTLCD for Arduino 2560. Are there any basic code or have anyone tried to run Mcufriend"s displays correctly?
I puzzled some hours with exactly the same hardware setup and made a quick & dirty, but successfully test script, combining LCD, Touch and SD Card Features.
This is a 3.2 inch TFT touch screen expansion board using standard Arduino Shield interface and it has good compatibility. It integrates a 3.2-inch touch screen, I2C temperature sensor, TF card holder, level conversion circuit, and the secondary development is easy.
