arduino tft lcd sd card in stock
The screen is 1.77" diagonal, with 160 x 128 pixel resolution. The TFT library interfaces with the screen"s controller through SPI when using the TFT library. Refer to the screen"s data sheet for complete details.
The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino screen. The Arduino specific additions were designed to work as similarly to the Processing API as possible.
The TFT library relies on the SPI library, which must be included in any sketch that uses the scree. If you wish to use the SD card, you need to include the SD library as well.
I am wondering which 1.8" TFT you are using. I bought a red DS Tech 1.8" TFT screen with a yellow, 11-pin header on one side and I soldered on a 4-pin header on the other side. I had to do some research, from which I gathered the following...
...in order for both the screen and the card reader to work, hardware SPI must be used. In the code at the top of this page, you have RST on pin 9 and DC on pin 8, but the Arduino TFT documentation has RST as 8 and DC as 9.

i just got an OPEN-SMART 3.2" TFT LCD shield with a built in SD card slot. I"m going to hook it up to an arduino mega. The LCD will function to accept string values keyed in by user. Is it possible to store the string values into the sd card. The reason being i would like to store all variable values of my sketch inside the SD card instead of the EEPROM of the arduino mega.
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 you to easily read full-color bitmaps from the SD card.

This is the new MEGA2560 R3. In addition to all the features of the previous board, the MEGA now uses an ATMega16U2 instead of the ATMega8U2 chip. This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.
The MEGA2560 R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The MEGA2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.

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)

The Shield TFT is usually supplied with an SD card module to store data or images. Touchscreen LCDs to display images and create graphical user interfaces. In this tutorial, we use the Kuman TFT 2.8″ shield (very similar to the 3.5″ shield) and we will see how to interface with the microSD card.
The shield is placed directly on an Arduino UNO or Mega board. The shield uses almost all the pins of the Arduino UNO. Make sure you don’t use the same ones for other modules. The SD card module of the TFT shield uses the SPI bus and selector pin 10.
The main interest of the MicroSD module on the TFT shield is to be able to store images in order to display them on the screen. If you don’t have a bitmap image at hand, you can download the one we use in this example.
We will create a button for each file and with the help of the previous function we will display the images contained in the SD card when we press the corresponding button.
Once the code is uploaded, a menu will appear with a button for each file contained on the SD card. If you press a button, the corresponding bitmap image will be displayed on the screen. If you press the screen again you will return to the main menu.
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.
This 2.0” LCD display adopts ST7789V driver chip and has 320*240 color pixels (RGB565), performing excellently in the angle of view (80/80/80/80). It supports SPI(4-wire) communication mode and GDI port (work with main-controllers with GDI), plug, and play. The module can be powered by 3.3V~5V, compatible with multiple main-controllers like Arduino UNO, Leonardo, ESP32, ESP8266, FireBeetle M0, and so on. Use the GDI interface to work with M0, which could effectively reduce wiring steps. Besides, there is an onboard MicroSD card slot for displaying more pictures.
