2.2 inch tft lcd display spi ili9341 free sample

I recently bought a Raspberry Pi and had bought a (2.2 Inch Serial TFT SPI LCD Screen Module HD 240 x 320 5110 Compatible) display off the web a while ago. I wanted to connect the two together, so not being able to find a specific sample on the web, I wrote my own.

Oldieman has provided details on how to get this working on the  Adafruit PiTFT Mini Kit 320x240 2.8" TFT+Capacitive Touch screen ADA1983. See his comments below...

ER-TFT022-1 is 240x320 dots 2.2" color tft lcd module display with ILI9341 controller,optional capacitive touch panel with controller FT6236U and resistive touch panel,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.It supports 8080 8-bit,9-bit,16-bit,18-bit parallel,3-wire,4-wire serial spi interface. FPC with zif connector is easily to assemble or remove.Lanscape mode is also available.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 2.2"TFT Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno.For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

When placing text, you can make life much easier by either letting it just "flow over the screen" completely (default behavior) or you can implement a kind of structure similar to a terminal ... where CR is decoded as CR/LF. In this case, you must clear from current character position to end-of-line... which implies you must map a character-ish concept of (X, Y). For font size lcd.setTextSize(2); I have already done this in my example code and I use a Y-decode scheme based on:

To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder Adafruit_ILI9341. Check that the Adafruit_ILI9341 folder contains Adafruit_ILI9341.cpp and Adafruit_ILI9341.

Place the Adafruit_ILI9341 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE

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.

The ILI9341 TFT module contains a display controller with the same name: ILI9341. It’s a color display that uses SPI interface protocol and requires 4 or 5 control pins, it’s low cost and easy to use.

The resolution of this TFT display is 240 x 320 which means it has 76800 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

The ILI9341 TFT display board which is shown in project circuit diagram has 14 pins, the first 9 pins are for the display and the other 5 pins are for the touch module.

So, the display part pins are numbered from 1 to 9 (from left to right): VCC (5V), GND (ground), CS (chip select), RST (reset), DC (or D/C: data/command), MOSI (or SDI), SCK (clock), BL (back light LED) and MISO (or SDO).

Pins D5 (GPIO14) and D7 (GPIO13) are hardware SPI module pins of the ESP8266EX microcontroller respectively for SCK (serial clock) and MOSI (master-out slave-in).

The first library is a driver for the ILI9341 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “ili9341” and choose the one from Adafruit).

The ILI9341 TFT display is connected to NodeMCU hardware SPI module pins (clock and data), the other pins which are: CS (chip select), RST (reset) and DC (data/command) are defined as shown below:

Full Arduino code:The following Arduino code is from Adafruit ILI9341 library (graphicstest.ino) with some modifications in order to work with the above circuit diagram.

I read in forums and could see that there were some adafruit libraries in the ESP8266 Arduino but now that it is not available and only some TFT_Touch_Shield_V2 are present.

//#define ILI9488_DRIVER // WARNING: Do not connect ILI9488 display SDO to MISO if other devices share the SPI bus (TFT SDO does NOT tristate when CS is high)
