arduino tft lcd screen datasheet brands

Arduino TFT LCD Screen is a backlit LCD screen with headers. You can draw text, images, and shapes to the screen with the TFT library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display. The micro-SD slot is accessible through the SD card library.

STONE will surely provide the right display solution for your needs anywhere you are on the globe.

You can check out http://www.elecfreaks.com/estore/displays/lcds/tft. They have adapters for both the UNO and Mega boards. I only use Mega 2560 boards when using displays since shields of 3.2 and larger require more resources. I can get Mega 2560 boards for between $8.00-$9.50 US. You should have no problem migrating to the Mega since the Arduino programming language is used for both the UNO and Mega. The only difference is the pin designations since the Mega has more pins than the UNO. I only use displays similar to what you find here:

These display units are themselves actual computers that are programmable using a drag and drop IDE interface. They interface well with the UNO and Mega (along with the Raspberry Pi) and use less resources than the ITDB Series. On the negative side, I feel that programming them with the Nextion IDE is less flexible than programming the ITDB series using UTFT and URTouch libraries.

The demo is developed based on the HAL library. Download the demo, find the STM32 program file directory, and open the LCD_demo.uvprojx in the STM32\STM32F103RBT6\MDK-ARM directory to check the program.

Open main.c, you can see all the test programs, remove the comments in front of the test programs on the corresponding screen, and recompile and download.

For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing in the directory STM32\STM32F103RB\User\GUI_DEV\GUI_Paint.c(.h)

image.cpp(.h): is the image data, which can convert any BMP image into a 16-bit true color image array through Img2Lcd (downloadable in the development data).

The Arduino TFT screen is a backlit LCD screen with headers. You can draw text, images, and shapes to the screen with the TFT library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.

The screen"s headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Uno, Leonardo, etc) or with the Arduino Due. To connect the screen to other Arduino boards, read the tutorial on this link.

The screen is 1.77" diagonal, with 160 x 128 pixel resolution. The TFT library interfaces with the screen"s controller through SPI when using the TFT library. Refer to the screen"s data sheet for complete details.

The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino screen. The Arduino specific additions were designed to work as similarly to the Processing API as possible.

The TFT library relies on the SPI library, which must be included in any sketch that uses the scree. If you wish to use the SD card, you need to include the SD library as well.

The Arduino Graphic LCD (GLCD) screen is a backlit TFT LCD screen with headers. You can draw text, images, and shapes to the screen with the GLCD library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display.

The screen"s headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Uno, Leonardo, etc. Datasheet You can use this module with Arduino Esplora.

This is the 2.4 inch touch screen for Arduino UNO and MEGA. It use 8-bit parallel bus, faster than serial SPI refresh , support 16-bit RGB 65K color display, display rich colors , easy to expand the experiment with SD card slot.
