adafruit 2.8 inch tft display brands
Adafruit 2.8 inch TFT LCD Touchscreen Breakout Board with microSD SocketThis colour 2.8 TFT display has 4 bright white LED backlight and 240 x 320 pixels with individual RGB pixel control. It has a resistive touchscreen to detect finger presses anywhere on the screen. The built-in controller has RAM buffering to take the workload away from the microcontroller. This display board has two modes: 8-bit and SPI.
It is 3 V to 5 V compliant with high-speed level shifters so you can use with any microcontroller. If you are using SPI mode, you can also take advantage of the on-board micro-SD card socket.Adafruit LCD Touchscreens
TFT TFT screens are a type of LCD screens that provide an even sharper and brighter image and are even flatter. The big difference with an LCD screen is that in the TFT screen for each sub-pixel a very small transistor is built into the glass plate that can contain the information of each sub-pixel.
Add some sizzle to your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection and a capacitive touchscreen. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
This shield is the capacitive version as opposed to the resistive touchscreen we also sell. This touchscreen doesn"t require pressing down on the screen with a stylus, and has a nice glossy glass cover. It is a single-touch display.
This shield uses SPI for the display and SD card and is easier to use with UNO, Mega & Leonardo Arduino"s. The capacitive touchscreen controller uses I2C but you can share the I2C bus with other I2C devices.
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. This shield needs fewer pins than our v1 shield, so you can connect more sensors, buttons and LEDs: 5 SPI pins for the display, 2 shared I2C pins for the touchscreen controller and another pin for uSD card if you want to read images off of it.
The display uses digital pins 13-9. Touchscreen controller requires I2C pins SDA and SCL. microSD pin requires digital #4. That means you can use digital pins 2, 3, 5, 6, 7, 8 and analog 0-5. Pin 4 is available if not using the microSD
The four sample codes: DisplayString, DrawGraphic, ShowBMP, and TouchPanel are used to display strings, graphics, pictures in BMP format, and touch pen functions.
Before performing the ShowImage display picture experiment, first, copy the pictures in the PIC folder in the data to the root directory of the SD card
Before experimenting with the TouchPanel, the touchscreen must be calibrated according to the displayed prompts. Open the corresponding project, burn the program, and you will be prompted when running:
The demos are developed based on the HAL library. Download the program, find the STM32 program file directory, and open the STM32 with four project folders: DisplayString, DrawGraphic, ShowImage, and Touchscreen.
