2 4 tft lcd shield mcufriend in stock
There are many tutorials on Arduino shields for 2.4 inch TFT LCD displays. In this road test I apply different tutorials to check the performance and issues of this specific shield: AZ-Delivery 2.4 inch TFT LCD display with resistive 4-wire touchscreen and an integrated SD card reader.AZ-Delivery 2.4 inch TFT LCD display.
TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology. That improves image quality, better contrast and addressability.
Depends on the needs of your project. Arduino UNO processor frequency is low. With the Arduino UNO full-color TFT LCDs are suitable to display simple data and commands. The TFT controller used cannot switch internal display RAM, so you can"t use the double buffer technique for animations but still you can only re-draw small sections of screen.
This module consumes most of the resources available in Arduino UNO. This is not a limitation of the module itself. In return, using a parallel interface allows you to quickly update the image. If you want to take advantage of all its functionality (LCD + touch screen + SD card), only pins 0 and 1 (RX and TX, respectively) and pin 19 (A5) remain unused. If the SD card is not used, pins 10, 11, 12 and 13 are additionally available. With a suitable layout, some SPI devices could be connected even if the SD card is used.
The module arrived well packed and in perfect condition. The board comes in a sealed antistatic bag, with protective foams to prevent the terminals from bending, and all this wrapped with a bubble bag and inside an individual cardboard box. The label on the antistatic bag indicates the controller is an ILI9341.
The PCB silkscreen indicates the main function of each pin, the labels are easy to read, although it does not show labels for the touch screen pins:Pin 9 - Touch X+ / LCD_D1
The SD card reader is very well located between the USB connector and the power connector, it does not touch either of them as it happens in other lcd tft shield modules and it is easily accessible to insert and remove the SD cards.
You can directly use the shield with any arduino uno. In this case we are using an Arduino UNO that exposes all the pins both on the header and on the board. In such a way that you do not need another shield to access the pins not used by the screen
ShieldCompatible with Arduino. 5V compatible, can be used with 3.3V or 5V logic. On-board 3.3 V (300mA LDO controller). The design is very well thought out and fits Arduino UNO perfectly.
2x74LVC245A Octal Bus Transceiver With 3-State outputs. This octal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The LVC245A is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses effectively are isolated. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment. This chip solves the problem of how to interface 3.3V logic devices to a 5.0V logic chip such as the Arduino. Most 3.3V devices do not like being run with 5V signals and can be damaged or flaky. The 74LVC245 is designed so that even when it runs at 1.8V, it still happily accepts 5V signals in one pin and converts it to a lower logic level on the opposite pin. It has 8 pipes it can convert but it won"t work with bi-directional/pull-up based devices such as I2C or 1-Wire. It does work great for SPI, Serial, Parallel bus, and other logic interfaces.
If you want to take advantage of all its functionality (LCD + touch screen + SD card), only pins 0 and 1 (RX and TX, respectively) and pin 19 (A5) remain unused. If the SD card is not used, pins 10, 11, 12 and 13 are additionally available. With a suitable layout, some SPI devices could be connected even if the SD card is used.
The ILI9341 which can control each pixel with a small number of pins. The shield connects ILI9341"s data pins 0-7 to Arduino digital pins 2-8 (allowing parallel communication, not SPI). ILI"s RESET goes to pin to Arduino analog pin A4.CS (chip select) to A3. RS (CD command/data) to A2. WR and RD to A1 and A0.
Includes a resistive 4-wire touchscreen (touchpad). The touch screen is attached on the surface of the display. Touch screen needs two analog inputs and two digital outputs. It connects through 4 wires, which share arduino pins 8, 9, A2, A3 with the ILI9341 driver. So you can"t write to LCD display and read the touch screen in the same time. I. Driver chip is XPT2046.
The resistive touch screen does not appear to appreciably affect the optical characteristics. Works properly, It takes a little pressure with the stylus for it to respond like in old mobile phones. You notice how it sinks into the screen when you press with the stylus. The stylus that comes with the module makes it easy to use if your interface design uses small controls. Some touch screen libraries offer better accuracy by specifying the resistance of the touch screen in the X direction. Resistance can be easily measured with a multimeter by connecting the test leads to the LCD_D1 - X + and LCD_DS X- terminals. Touch is sensitive to pressure.

Only US$8.99, buy best 2.4 inch tft lcd shield ili9341 hx8347 240*320 touch board 65k rgb color display module with touch pen for uno geekcreit for arduino - products that work with official arduino boards sale online store at wholesale price.
With this information and the information about the touchscreen I tried several ID hardcoded to get the screen to work. Most of the HX8357 id provides output, but ID ILI9341 240x320 ID=0x9341 seems to provide best results.
Im new to Arduino myself but i do have the same screen which works perfect,your problem is probably that the TFT shield is shorting off the top off the arduino usb put something non conductive there and reset. if your still having trouble, try removing the shield and watch each pin as you insert it to make sure they are all inserted in the correct pins, LCD_02 should be in Dig pin 2.
I have one of these TFT LCD shields, but mine is a ILI9335. It has taken me nearly 2 weeks to find a working Library and code for my 9335 driver and I am now setting about creating sketches based around my working Library.
Unfortunately most sellers of these shields (excluding good reputable companies) do not adivise of which Driver is onboard the shield and it becomes difficult to locate a working Library for the driver of the purchased shield.
You have an 8-bit parallel interface TFT display. It requires 13 GPIO pins - D0-D7 plus reset, chip select, read, write and register select. You can forego the "read" signal and tie it high to save a pin. You can probably do the same with the reset signal, meaning you need a minimum of 11 pins.
I am not sure the NodeMCU has that many available, does it? (maybe it does, I don"t have one to hand right now), so you may want to try getting it going with an SPI or I2C IO expander (though slowly).
This folder has some examples of using the TFT. If you want to use the touch screen version, I recommend reading the touch calibration process carefully. See SI47XX_02_TFT_TOUCH_SHIELD below.
Folder SI47XX_10_RDS has almost the same examples found here. The main difference is the RDS support. Also, SI47XX_10_RDS is updated more frequently. I recomend you to use the SI47XX_10_RDS folder instead.
This sketch uses an Arduino Pro Mini, 3.3V (8MZ) with a SPI TFT from MICROYUM (2” - 176 x 220) based on ILI9225 driver. The Arduino library used to control that display device is MCUFRIEND_kbv. Please, install it before start working with this sketch.
It is also a complete radio capable to tune LW, MW, SW on AM and SSB mode and also receive the regular commercial stations. It is important to know the SSB support works on SI4735-D60 and SI4732-A10 devices.
If you are using the same circuit used on examples with OLED and LCD, you have to change some buttons wire up. This TFT device takes five pins from Arduino. For this reason, it is necessary change the pins of some buttons. Fortunately, you can use the ATmega328 analog pins as digital pins. The table below.
The Arduino library used to control the TFT shield from mcufriend or equivalent, is the MCUFRIEND_kbv. Please, install this library before start working with SI47XX_02_TFT_TOUCH_SHIELD sketch.
All toutch screen needs to be calibrated to work properly. To do that, use the TouchScreen_Calibr_native.ino that comes with MCUFRIEND_kbv library. Read the TouchScreen_Calibr_native.ino and check the XP, XM , YP and YM pins configuration. You might need to change the XP, XM , YP and YM values in the TouchScreen_Calibr_native.ino depending on the display you are using. In the TouchScreen_Calibr_native.ino sketch, check the corresponding code lines as shown below.
Finally, you must copy and paste the two lines highlighted above to the SI47XX_02_TFT_TOUCH_SHIELD sketch. The following code illustrates this action.
The purpose of this example is to demonstrate a prototype receiver based on the SI4735 and the “PU2CLR SI4735 Arduino Library” working with the TFT ST7735 display. It is not the purpose of this prototype to provide you a beautiful interface. To be honest, I think you can do it better than me.

(1) You have to press the push button and after, rotate the encoder to select the parameter. After you activate a command by pressing a push button, it will keep active for 2,5 seconds.
(2) The SEEK direction is based on the last movement of the encoder. If the last movement of the encoder was clockwise, the SEEK will be towards the upper limit. If the last movement of the encoder was ounterclockwise, the SEEK direction will be towards the lower limit.
Actually a cheap color display has lot of advantages over any other type displays. Monochrome graphic LCD display actually costs same. Other options of cheap display is Nokia 5110 Display (which is often reported by many users as buggy), standard 1602A LCD Display (which is an all purpose standard basic LCD display). Here is Getting Started Guide For Arduino TFT Touch Screen Shield Manufactured by MCUFRIEND. This is possibly the cheapest 2.4″ color display for Arduino. It costs around $8 to $10. MCUFriend is a China company and has an useless website. However, all over the web, there is huge support for this cheap display. The display works as intended. I purchased it from physical shop. It is a 2.4″ diagonal LCD TFT display, has white-LED backlight, resistive touchscreen, 240×320 resolution, has SPFD 5408 controller with built in video RAM buffer, has 8 bit digital interface and 4 control lines, it uses digital pins 5-13 and analog 0-3. there is a micro SD card reader.
For Arduino UNO, you are actually having digital pins 2, 3, analog 4, analog 5 unoccupied by the shield. If you do not use the SD card slot then digital pin 12 is also available. 3 digital pins and 2 analog pins should be good for most of the basic projects but for multiple sensors, the actual need will be towards Arduino Mega instead of Arduino UNO. This shield does work with Arduino Mega but sometime oddly behave (may be there is some other problem with my piece). I lack idea whether the micro SD card slot actually works.
Obviously as it is a shield, it is challenging to use the unoccupied pins. The easy trick is use to pass a single stranded wire. I read somewhere that it is possible to control the backlight by connecting a digital pin and transistor.
In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.
There are several components to achieve this. LEDs, 7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.
TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.
In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.
In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.
The display driver will typically accept commands and data using an industry-standard general-purpose serial or parallel interface, such as TTL, CMOS, RS232, SPI, I2C, etc. and generate signals with suitable voltage, current, timing and demultiplexing to make the display show the desired text or image.
The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.
Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.
while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)
while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)
A while ago I bought this 2.4"" Inch TFT LCD Touch Display Shield for Arduino UNO, but only recently I came up with a project where I could make use of this piece of hardware.
Then, instead of calling the method tft.clor565, a call to the newly created function fixed_color565 made sure that images got displayed correctly from now on..
This post explains about how to display text on TFT lcd using arduino uno? TFT which is used in the tutorial is 2.4′ TFT by Mcufriend. It has ST7781 controller in it, Driver code is ST7783. This 2.4 inch TFT Lcd is arduino compatible. It can easily be mounted on an Arduino uno board. This TFT can be interfaced in 32,16 and 8 bit parallel mode. It also supports I2c Mode. In this tutorial i am going to interface it in 8-bit parallel mode with arduino uno.
Project code is below. I am not using any predefined library for displaying text on TFT lcd, I actually didn’t find any library that can properly display text on the TFT i have, all the libraries through which i have gone through were unable to initialize my lcd driver properly. So i decided to first read the driver of the TFT and then write my own code according to the driver supported commands. I first read the TFT Driver. To learn about how to check the TFT Lcd driver just go through this small tutorial.
After reading the driver of TFT i went through its datasheet. The TFT which i have is working with ST7781 controller, it’s a Chinese manufactured TFT by Mcufriend, their website says that the TFT is working on ILI9321 driver but its not. The information on ther website is misleading everyone, I have seen many posts on internet that talks about the Mcufriend TFT Lcd driver. So if you have a TFT and you are unable to find its driver than go through the above tutorial.
The TFT use in project can easily be mounted on any Arduino board. I mounted it on Arduino uno. You can also use any other Arduino board but for that you have to make changes in the code.
Changing the code is not a hard task if you understand the code written below. Coming to the Code. I first initialized the TFT Controlling pins LCD_RST, LCD_CS, LCD_RS, LCD_WR, LCD_RD. In the Setup function I made the Port-D and Port-B of Arduino Uno as output Port. Since the data pins of TFT is interfacing with Port-D and Port-B of Arduino so to write data and commands to TFT we have to declare Port-D and Port-B as output. Then the function InitializeTFT() is initializing the TFT.
In the Loop function i am filling TFT with colours. Colors are filled in Horizontal and vertical directions. According to the data sheet which says you can display text on TFT in eight directions.
The Code above will fill TFT with colors and the code below is displaying text “www.microcontroller-project.com” on TFT. Try to first understand the above code before moving to the code below. Above code is simply a method to fill the pixels of TFT. If you grabbed the process of filling TFT Pixels than you can display any text on lcd by manipulating the pixels.
We pass ISO900, ISO14001 and TS16949 certificates.Strict quality control Inspection is done in FOG==>LCM==>LCM+ RTP/CTP==> production online inspection ==>Q.C inspection==>aging test 4 hours with load in 60 ℃ special room (as option)==>OQC
2)When EOL happens,usually we will get notification from original manufacturer 3-6 months in advance. We prepare another LCD brand solution as replacement for you or recommend you to do last buy if your annual quantity is small or even tool up a new LCD panel if your annual quantity is big.
2)The material we are using are all A grade from formal channels,with strong anti-shock capacity, anti-high-temperature capacity, high reliability and very low rate of reject.
In this tutorial we are going to learn how to make Arduino Calculator with TFT Display. Our calculator’s precision is up to two decimal points and you can add, subtract, multiply or divide up to 4 digit per number. Obviously you can add more number of digits if you want.
You have to just add number by touching on screen, maximum digits per number allowable is 4 and then select operator and add again second number, press on equal. Finally, you got the result on screen, Congratulation you have made your own Arduino Calculator with TFT Display.
