tft display with sd card factory

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:

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.

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

Thanks for the feedback, I have tested it on 5V, it seems no problem for testing, for the LED backlight it has to be 3V3, or 5V with 10K resistor, for the VCC, not sure which have to be used. It seems the factory provided info it not fully promising.

The 2.2″ version is perfect for displaying complex information due to the 320×240 pixel area. Power consumption is reasonable. Be aware of the 3.3V levels since 5 volts will destroy your display (sooner or later). Most ARM boards will come with 3.3V levels anyway and even Atmel ATmega will work on 3.3 volts (but with lower frequency)

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.

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.

I"ve combined the BLE Shield and the OLED (SSD1351) TFT display and have this working very nicely - taking data from the Bluefruit iPhone APP - then displaying different things on the screen.

I"m more a software guy than Hardware - and need to know if I can use the wiring I currently have ....or modify easily to do what works now PLUS read the card.

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

This awesome little display breakout is a great way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

This 2.2″ display has 320×240 color pixels and is a true TFT display. The TFT driver (ILI9340 or compatible) can display full 18-bit color (262,144 shades). The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. Adafruit also had a little extra space on the back so there is a microSD card holder for easily loading full-color bitmaps from a FAT16/FAT32 formatted microSD card.

The Adafruit 2.2″ TFT LCD with MicroSD Card also features an EYESPI connector for a simpler connection to the LCD. EYESPI is a single 18-pin FPC used as a quick way to connect displays.
