3.2 inch ili9341 tft lcd datasheet made in china

I purchased this LCD Touch along with the TFT LCD Mega Shield 2.2 shield for the Arduino Mega also from Amazon. It was easy to figure out getting the UFTF library from Rinky Dink Electronics to work. I used "UTFT myGLCD(CTE32_R2,38,39,40,41);" or "UTFT myGLCD(ILI9341_16,38,39,40,41);" and they both worked. I had a very hard time getting the actual touch function to work. The default of "URTouch myTouch(6, 5, 4, 3, 2);" for the touch library is correct on the Mega. It turned out to be a connection issue. I just reseated the board a couple of times and it worked. I recommend testing this LCD with the examples from the URTouch library. The online examples are too complicated and have too many dependencies to break. Get the basic screen and touch working first. Don"t forget to debounce the touch with a short delay. This screen is touchy which makes it fast to enter numbers for me. It worked just powered from my PC with a USB cable to the Arduino Mega. Very Easy.

ILI9341 is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with resolution of 240RGBx320 dots, comprising a 720-channel source driver, a 320-channel gate driver, 172,800 bytes GRAM for graphic display data of 240RGBx320 dots, 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). The moving picture area can be specified in internal GRAM by window address function. The specified window area can be updated selectively, so that moving picture can be displayed simultaneously independent of still picture area.

You can find ILI9341-based TFT displays in various sizes on eBay and Aliexpress. The one I chose for this tutorial is 2.2″ length along the diagonal, 240×320 pixels resolution, supports SPI interface, and can be purchased for less than $10.

Note that we will be using the hardware SPI module of the ESP8266 to drive the TFT LCD. The SPI communication pins are multiplexed with I/O pins D5 (SCK), D6 (MISO), and D7 (MOSI). The chip select (CS) and Data/Command (DC) signal lines are configurable through software.

For ILI9341-based TFT displays, there are some options for choosing the library for your application. The most common one is using Bodmer. We will use this library in this tutorial. So go ahead and download the

The library is based on the Adafruit GFX and Adafruit ILI9341 libraries and the aim is to retain compatibility. Significant additions have been made to the library to boost the speed for ESP8266 processors (it is typically 3 to 10 times faster) and to add new features. The new graphics functions include different size proportional fonts and formatting features. There are a significant number of example sketches to demonstrate the different features.

Configuration of the library font selections, pins used to interface with the TFT and other features is made by editting the User_Setup.h file in the library folder. Fonts and features can easily be disabled by commenting out lines.

Now you are all set to try out tons of really cool built-in examples that come with the library. The following output corresponds to the TFT_Pie_Chart example.

My favorite example is TFT terminal, which implements a simple “Arduino IDE Serial Monitor” like serial receive terminal for monitoring debugging messages from another Arduino or ESP8266 board.

ILI9341 is a 262144-color TFT LCD driver chip with a resolution of 240x320 (RGB) and 172820 (240 x 320x 18/8) bytes of RAM. Each pixel depth can reach 18 bits.

According to the above figure, ILI9341 is in the 16-bit mode and the available GRAM data are D17~D13 and D11~D1. D12 and D0 are not used. Actually, D12 and D0 of ILI9341 are not adapted in our LCD module. D17~D13 and D11~D1 of ILI9341 correspond to D15~D0 of MCU. In the 16-bit data of the MCU, the lowest 5 bits represent blue, the middle 6 bits are green, and the highest 5 bits are red. The larger the value, the darker the color.

The 8080 interface is designed by Intel. It is a parallel, asynchronous, half-duplex communication protocol. It is used for external expansion of RAM and ROM and is also used for LCD interface later.

This manual uses the development board of the main control chip STM32F103RCT6 to illustrate the basic usage of this LCD. Users can also use other similar development boards for development.

//The above are the basic functions for reading and writing; if you want to operate IO analog with the FSMC of the STM32, you can refer to LCD + TouchPanel (8080 FSMC) demo.

Initialization of LCD registers, the following initialization values of the registers are provided by the original LCD manufacturer and can be displayed normally according to the following configuration, please refer to the chip manual for registers.

Checking a TFT lcd driver is very messy thing especially if its a Chinese manufactured TFT. TFT’s that are supplied by Chinese manufactures are cheap and every body loves to purchase them since they are cheap,but people are unaware of the problems that comes in future when finding the datasheet or specs of the particular TFT they purchased. Chinese manufactures did not supply datasheet of TFT or its driver. The only thing they do is writes about the TFT driver their lcd’s are using on their websites. I also get in trouble when i started with TFT’s because i also purchased a cheap one from aliexpress.com. After so many trials i succeeded in identifying the driver and initializing it. Now i though to write a routine that can identify the driver.

I wrote a simple Arduino Sketch that can easily and correctly identify the TFT Lcd driver. I checked it on 2.4, 3.2 and 3.8 inch 8-bit TFT lcd and it is identifying the drivers correctly. The drivers which i successfully recognized are ILI9325, ILI9328, ILI9341, ILI9335, ST7783, ST7781 and ST7787. It can also recognize other drivers such as ML9863A, ML9480 and ML9445 but i don’t have tft’s that are using this drivers.

The basic idea behind reading the driver is reading the device ID. Since all the drivers have their ID’s present in their register no 0x00, so what i do is read this register and identify which driver tft is using. Reading the register is also a complex task, but i have gone through it many times and i am well aware of how to read register. A simple timing diagram from ST7781 driver explains all. I am using tft in 8-bit interface so i uploaded timing diagram of 8-bit parallel interface. The diagram below is taken from datasheet of ST7781 tft lcd driver.

The most complex tft i came across is from a Chinese manufacturer “mcufriend”. mcufriend website says that they use ILI9341 and ILI9325 drivers for their tft’s. But what i found is strange their tft’s are using ST7781 driver(Device ID=7783). This is really a mesh. I have their 2.4 inch tft which according to their website is using ILI9341 driver but i found ST7783 driver(Device ID=7783). The tft i have is shown below.

I am using Arduino uno to read driver. I inserted my lcd on arduino uno and read the driver. After reading driver i am printing its number on Serial Monitor.

Note:On serial monitor driver number will be displayed like if your lcd is using ST7783 controller than on serial monitor 7783 will be displayed or if tft is using ILI9341 than on 9341 will be displayed.

The code works on Arduino uno perfectly but if you are using any other board, than just change the pin numbers according to the board that you are using also check out for the Ports D and B. TFT Data Pin D0 is connected to Port-B Pin#0 and D1 is connected to Port-B Pin#1. TFT Data Pins D2 to D7 are connected to Port-D Pins 2,3,4,5,6,7. So if you are using Arduino mega than check for the Ports D and B and Make connections according to them. Arduino mega is working on ATmega2560 or ATmega1280 Microcontroller and Arduino uno is working on ATmega328p Microcontroller so both platforms have ports on different locations on arduino board so first check them and then make connections. The same process applies to all Arduino boards.
