2.2 inch tft lcd display spi ili9341 in stock
ILI9341 is a 262144-color single-chip SOC driver for a TFT liquid crystal display with resolution of 240x320 dots (RGB), comprising a 720-channel source driver, a 320-channel gate driver, 172800 bytes GRAM for graphic display data of 240x320 dots (RGB), and power supply circuit.
ILI9341 supports parallel 8-/9-/16-/18-bit data bus MCU interface, 6-/16-/18-bit data bus RGB interface and 3-/4-line serial peripheral interface (SPI).
ILI9341 can operate with 1.65V ~ 3.3V I/O interface voltage and an incorporated voltage follower circuit to generate voltage levels for driving an LCD.
ILI9341 supports full color, 8-color display mode and sleep mode for precise power control by software and these features make the ILI9341 an ideal LCD driver for medium or small size portable products such as digital cellular phones, smart phone, MP3 and PMP where long battery life is a major concern.
The DT022BTFT uses the same connections as the DT022CTFT, with the exception of the backlight (which has connections shown in the Displaytech datasheet).
The provided display driver example code is designed to work with Microchip, however it is generic enough to work with other micro-controllers. The code includes display reset sequence, initialization and example PutPixel() function. Keep the default values for all registers in the ILI9341, unless changed by the example code provided.
4-wire 8-bit Serial Data Interface II is the correct mode to use based on the microprocessor pins available. This mode is closest to standard SPI port operation with a few minor exceptions.
Note that the WR pin becomes the D/CX signal in serial mode. CS is used to initiate a data transfer by pulling it low. At the end of the data transfer, pull the CS pin high to complete the transaction. The timing diagram indicates that you can pull the CS pin high in between the command byte and data bytes within a transfer, but it is unlikely needed if the display is the only device on the SPI bus. To keep things simple, we suggest to leave it low during the entire transaction.
The D/CX pin tells the ILI9341 that the current byte is either command or data. Pull the D/CX pin low when the current byte is a command, and pull high when it is data. The timing diagram indicates only needing to set D/CX on the last bit of a byte, but it is much simpler to just leave it high or low during the entire byte.
Use this 2.2" Color TFT LCD Display to add a vibrant color display to your Raspberry Pi projects. Just wire up your display and use the SPI protocol to communicate with your TFT. This is more advanced than our Raspberry Pi LCD shields since you have to wire using a breadboard and use the fbtft Raspberry Pi Library when configuring so we recommend it for intermediate users.
For Arduino users, this display is also Arduino compatible however we recommend our 11 Pin 2.2" TFT LCD Display which can be plugged directly into an Arduino UNO or Mega so you don"t have to use a breadboard.
TFT LCD module has always been one of the hot products in DIY industry and LCD is basically the necessary products during all projects, at the same time, serial port modules are also the popular ones, because it takes few IO and the usage is simple. This section of the 2.2 inch TFT LCD serial SPI integrated features of compact, SPI interface.
The LCD drive ic is ILI9341. It"s a 240 * 320 (resolution), 2.2 inch TFT LCD screen. The LCD has a wide viewing angle, the contrast is also very suitable.
