arduino tft lcd sd card factory

A micro sd card module is preferred in cases you need to store large amounts of data and other information for your Arduino project. The EEPROM of the Arduino microcontroller has a limited storage capacity and is specific with the format and nature of data it can hold. This makes it not the best for storing data like text, CSV, audio, video or image files.

A 74LVC125A Level Shifter on the module converts the interface logic from 3.3V-5V to 3.3V. This enables us to use this device with both 3.3V and 5V microcontrollers like Arduino.

Before inserting the micro SD card into the module and hooking it up to the Arduino, make sure it is properly formatted and is using the FAT16 or FAT32 file system. Most new SD cards come when already pre-formatted with a FAT file system but it’s always good to do it yourself to be certain.

The SD card module uses the SPI communication protocol and is therefore connected to the Arduino hardware SPI pins. The SPI pins depend on the type of Arduino used but in this case we are using the UNO whose SPI pins are from pin 10 to 12.

The connections are done as shown below. Make sure you don’t change the order of connection for the SCK, MOSI and MISO pins because they are declared in that order within the SD.h library.

The CardInfo sketch will not write any data to the card but it tells you if the card is recognized and also displays some information about it. This information is shown in the serial monitor like shown below.

After running the CardInfo sketch, you can run other sketches like the ReadWrite sketch so that you can learn how to use the various functions for reading and writing data to the SD card.

After setting up the micro SD card module for use with Arduino, we can now be able to store data like images in the sd card and display them on a TFT LCD screen. The best images to display are bitmap images so make sure you convert your images to bitmap format before storing them into the SD card. You can use an online image convertor.

Another important aspect you should keep in mind when converting your images is the size of the images. This depends on the size of the screen you are using, for example am using a 128×128 pixels screen therefore my images should be that size. Also make sure the images don’t exceed 60kb so that the can easily be processed by the microcontroller to be displayed on the TFT screen.

Searching for a method to display the directory content of an SD card directly on the TFT screen did not lead to the necessary information. All I could find was a nice sketch to show the content on the Serial Monitor using the SdFat library ( => https://www.arduino.cc/en/Tutorial/CardInfo ). However, like in this sketch, using a second Arduino board containing an SD card could successfully redirect the input stream via Serial2 to the TFT display on the first board. But it did not work for redirection to the same board.

The solution: For the redirected input stream (&tft) to the TFT board an additional print command is necessary. So this looks like => tft.println(sd.ls(&tft,LS_R)); and this works!

Anyway now I commented that line, beacuse I am not interested in speed right now. But now the problem seems to be the programation code. the error message is as follows: ( I am using Arduino 1.8.7)

I found the TFT screen and Uno on Banggood.com about a month ago and over the weekend I was messing with the pair and found the tftbmp draw code in the demo.. I extended it with the ability to read any bmp file on the SD card.. so all you do is put your bitmaps on the SD and plug it in.. Having to add/edit/recompile/reload the Uno everytime is BS... Here is my code:

This ST7735S 1.8" TFT Display features a resolution of 128×160 and SPI (4-wire) communication. Integrated with an SD card slot, it allows to easily read full-color bitmaps from the SD card. The module provides users with two wiring methods: pin header wiring and GDI (General Display interface). You can directly use an FPC cable to connect the display to any controller with GDI interface like FireBeetle-M0. Plug and play, easy to wire. Besides, the display supports low refresh rate and offers good display effect and strong versatility. It can be used in applications like sensor monitoring and alarm, Arduino temperature monitor, fan controller, etc.

This product is a breakout module that features SPI communication mode and onboard GDI interface, which could reduce the complexity of wiring. It can easily display the read content from the SD card.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 320x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6236 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.

The pin32 (SDO) of 3.5 display module is also used by touch panel or SD card SPI interface, so we must cut off this pin to avoid conflict with the touch panel or SD card.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (Due/Mega 2560).

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

The component TFT supports a 2.8 inch TFT display with a resolution of 240*320 pixels.The display is not soldered on the board, but there is a 14 pin connector for a TFT display. The ILI9341 has been tested.

There are four sample projects for the Arduino IDE which could be downloaded: TFT-Box3D (download here), TFT-Graphic-Test (download here), TFT-HelloWorld (download here) and TFT-HowToUseFonts (download here). And there are two examples for the Arduino IDE for using the touch functionality which could be downloaded: TFT-TouchBtn (download here) and TFT-TouchDraw (download here).

There are two dip switches for the component: SW311 and SW314. If you want to use the TFT display all switches on SW311 have to be on on. If you additonally want to use the touchpad of the display all switch of SW314 have to be on. The following two tables shows the functions and the potential conflicts with other components

RFID, SW303-3, MISO; Gyro, SW310-3, SDA/SDI; OLED, SW309-2, SDA; mikroBus, SW405-2, MISO; Unit-Bus, SW200-2, CN212 - PIN 5; Grove I2C, SW203-1, S2C - SDA

After the download it"s necessary to add both libraries to your Arduino IDE. Open Sketch > Include Library > Add .ZIP Library ... and select the downloaded archive. Do it for both libraries.

Just tested the 2.2″ version. Easiest way to control it from an Arduino is by using the Adafruit ILI9340 library. Made a video of the example sketch that comes with the library: http://www.youtube.com/watch?v=bVzZ6PWFbGE

The description says you can use 5V for VCC. That’s wrong. By using 5V the module will get too hot and will not work. Use 3.3V and the module will work. You can use a voltage divider for your 5V Arduino.

nice unit. got the 2.2″ version for my signal generator project (based on the AD9850 module i got from here also). clean and clear, very happy with it.. got it working with a couple of different libraries, mainly Adafruit and UTFT.

2.2” – Nice colors, easy integration with Arduino Uno and Teensy++2.0 . Only 3 stars because of the limited angle of view and issues withh the edge most lines.

This guide is about DWIN HMI Touch Screen TFT LCD Display. HMI Means Human-Machine Interface. DWIN is specialized in making HMI Touch screen displays that are compatible with all microcontrollers like Arduino, STM32, PIC, and 8051 families of Microcontrollers.

This is a Getting Started tutorial with 7-inch DWIN HMI TFT LCD Display. We will see the architecture, features, board design, components, and specifications. We will also learn about the TTL & RS232 interfaces. Using the DGUS software you can create UI and with SD Card you can load the firmware on display memory.

On the LCD board, you can see the flip-open connector. Just flip open the connector and insert the FCC cable. Keep in mind that the blue ends should be on top. Now you can just press the lock so the FCC cable is locked.

One of the method to load the firmware to the T5L DWIN LCD Display is by using the SD Card. An SD Card of up to 16GB can be used to download the firmware files. We can easily insert the Micro SD card into the SD Card slot on the backside.

But we need to format this SD card in a FAT32 file system. You can insert the SD Card into your computer using the SD Card Adapter and perform a quick format.

After copying the file, remove the SD Card from your computer and insert it into the SD Card slot of DWIN LCD Display. Then power the display using the USB Cable. The firmware downloading process will start automatically.

The next part of this tutorial includes creating UI and interfacing DWIN LCD Display with Arduino. For that you can follow the DWIN LCD Arduino Interfacing Guide.

This is a 3.5-inch 320 * 480 resolution TFT colour screen. It supports working boards such as Arduino Uno and Arduino mega2560 and Arduino due. Also supports STM32, 51 and other conventional microcontrollers.

When using this screen, you do not need any wiring operations, just plug onto your Arduino board, we will provide the corresponding Arduino library files, the development code is open source, you can use Arduino and this screen to build some awesome applications and games!

Open Arduino IDE, find TFT_eSPI in the file and example, the T-Display factory test program is located at TFT_eSPI -> FactoryTest, you can also use other sample programs provided by TFT_eSPI

3 In the Arduino IDE tool options, select the development board ESP32 Dev Module, select Disable in the PSRAM option, select 4MB in the Flash Size option, Other keep the default

The 2.8 inch TFT LCD Touch Display is fully assembled, tested and ready to go. Add the touch display without wiring, no soldering! Simply plug it in and load up a library – you’ll have it running in under 10 minutes! Works best with any classic Arduino ATMEGA328 Board. So spice up your Arduino UNO project with a beautiful large touchscreen display shield with a built-in microSD card connection. This TFT display is big (2.8″ diagonal) bright (4 white-LED backlights) and colorful (18-bit 262,000 different shades). The Display comes with 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

SainSmart 2.8" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controllerILI9325, it"s a support 8/16bit data interface , easy to drive by many MCU like arduino families,STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC isXPT2046, and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

Voltage type: 5v or 3v voltage input voltage,input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.(Click here)
