SainSmart 3.2" 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 controller SSD1289, it"s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is ADS7843 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

Note:The SD library only can be use in version arduino-00xx and the library only supports FAT16 fomatted SD card up to 2GB, so you need to fomat your SD card to FAT16. 4GB FAT16 fomatted SD card is tested not working. Long file names are not supported. Keep your file names compliant with 8.3 standard.

LCD-specified initialization code is provided, so that you can save time to optimize power control register and gamma curves for best display performance. We have test the provided code, it gives the best display performanace

It is 100% compatible with the normal MCU like ARM AVR PIC and 8051,especially on Arduino family such as Arduino Due and Arduino MEGA2560(R3).The module uses the LCD controller Chip SSD1963 with 7 inch LCD including the touchscreen.

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.

Reason: The hooks on the backight of ER-TFT032-3.1 is always complained by most customers for inconvenient assembly. So we cancel the hooks in the new version of ER-TFT032-3.2.That"s the only difference for these two versions.

ER-TFT032-3.2 is 240x320 dots 3.2" color tft lcd module display with ILI9341 controller and optional 4-wire resistive touch panel and 3.2 inch capactive touch panel with controller FT6236,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.It supports 8080 8/16-bit parallel,3/4-wire serial interface. FPC with zif connector is easily to assemble or remove.Lanscape mode is also available.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 3.2"TFT Touch Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

Spice up your Arduino project with a beautiful touchscreen display shield with built in microSD card connection. This TFT display is 2.4" diagonal and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. As a bonus, this display has a optional capacitive touch panel and resistive touch panel with controller XPT2046 attached by default.

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 (UNO/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!

2012 latest IIC LCD2004-character LCD display module, a new high-quality 4 line 20 character LCD module not only set the contrast control knob selector switch also has a backlight and IIC communication interface. For Arduino beginners, not for the cumbersome and complex LCD driver circuit connection and a headache, the real significance of this LCD module will simplify the circuit, this module directly into the Arduino Sensor Shield V5.0 sensor expansion board IIC device interface can, GM 4P sensor connection cable, programmed through the Arduino controller, you can easily identify the slogan, sensor data records.

I am about to get my first Teensy 3.1 to use in my project, I need to connect the Sainsmart 1.8" TFT display, I was wondering how I would do this. The display uses SPI and I need to connect SCL, SDA, RS/DC, RES, and CS pins.

That wiring graphic for ILI9341 is very well defined for sure, if the SD circuit on the sainsmart display is usable and you want to use it then mentioning that it needs a unique CS signal from Teensy may be helpful - Edit: I mean that the rest of the (apparently) separate lines of the two sets SPI pins should be safe to tie; I have not looked at the DS nor schematic for the display so there may be something which makes this a bad idea but not likely imho.

Indeed - the PJRC ILI9341 page and product and code worked as shown for me enough to solder wires and have it work the first time. I saw post that showed the edits needed (https://forum.pjrc.com/threads/28106-Display_ili9341?p=72889&viewfull=1#post72889)to use the SD portion (resistor removal/bypass) but I had unhooked mine and not gotten back to it yet. Here view of how fast the Teensy can push the ILI9341 (http://hackaday.com/2014/08/18/tft-lcds-hit-warp-speed-with-teensy-3-1/)

So here"s the deal on this screen: It"s a 7" (or 5 depending who you ask) HDMI LCD screen with GPIO pins for touch capability. I purchased it from "sainsmart" who sold it to me as a 7" HDMI LCD screen (800x480)

Searching the driver package on the pre-built image (5_HDMI_LCD.tar.gz) leads me to waveshare"s 5" screen.....I have tried their drivers, and they work exactly the same as the ones provided by sainsmart. I"m assuming one of those manufactures is copying the other. In any case!

Unit came broken. Panel was separated from the board. Connector was damaged. As noted by others, the documentation and sample code from SainSmart is pretty awful. Finally found a link to this: http://www.instructables.com/id/Mini-Arduino-enviroment-monitor/?ALLSTEPS

From another reviewer (Note: Compare the pin-outs carefully to the #define statements in the libraries. Current versions have the TFT_RST and TFT_DC pins swapped to what this article states)

Adafruit_ST7735 is the library we need to pair with the graphics library for hardware specific functions of the ST7735 TFT Display/SD-Card controller.

In the file dialog select the downloaded ZIP file and your library will be installed automatically. This will automatically install the library for you (requires Arduino 1.0.5 or newer). Restarting your Arduino software is recommended as it will make the examples visible in the examples menu.

The easiest way to remedy this is by extracting the GitHub ZIP file. Place the files in a directory with the proper library name (Adafruit_GFX, Adafruit_ST7735 or SD) and zip the folder (Adafruit_GFX, Adafruit_ST7735.zip, SD.zip). Now the Arduino software can read and install the library automatically for you.

Basically, besides the obvious backlight, we tell the controller first what we are talking to with the CS pins. CS(TFT) selects data to be for the Display, and CS(SD) to set data for the SD-Card. Data is written to the selected device through SDA (display) or MOSI (SD-Card). Data is read from the SD-Card through MISO.

So when using both display and SD-Card, and utilizing the Adafruit libraries with a SainSmart display, you will need to connect SDA to MOSI, and SCL to SCLK.

Note: Adafruit displays can have different colored tabs on the transparent label on your display. You might need to adapt your code if your display shows a little odd shift. I noticed that my SainSmart display (gree tab) behaves best with the code for the black tab – try them out to see which one works best for yours.

#define sclk 4 // SainSmart: SCL#define mosi 5 // SainSmart: SDA#define cs 6 // SainSmart: CS#define dc 7 // SainSmart: RS/DC#define rst 8 // SainSmart: RES

#define sclk 13 // SainSmart: SCL#define mosi 11 // SainSmart: SDA#define cs 10 // SainSmart: CS#define dc 9 // SainSmart: RS/DC#define rst 8 // SainSmart: RES

You can name your BMP file “parrot.bmp” or modify the Sketch to have the proper filename (in “spitftbitmap” line 70, and in “soft_spitftbitmap” line 74).

#define SD_CS 4 // Chip select line for SD card#define TFT_CS 10 // Chip select line for TFT display#define TFT_DC 9 // Data/command line for TFT#define TFT_RST 8 // Reset line for TFT (or connect to +5V)

#define SD_CS 4 // Chip select line for SD card#define TFT_CS 10 // Chip select line for TFT display#define TFT_DC 9 // Data/command line for TFT#define TFT_RST 8 // Reset line for TFT (or connect to +5V)

As you have seen before the Adafruit_GFX library (supported by the Adafruit_ST7735 library) makes this easy for us – More information can be found at the GFX Reference page.
