sainsmart 1.8 st7735r tft lcd in stock
The 1.8" TFT LCD SPI-bus display modules available from Adafruit and SainSmart are functionally equivalent, except that the SainSmart unit can be driven at a much faster SPI bus rate than the Adafruit (32 MHz vs. 4 MHz in my testing). Fabien Royer has shown that this is due to a slow level shifter in the Adafruit unit.
The board supports multiple different 1.8" panel pinouts including Adafruit and SainSmart, and sports mounting pads for three GPIO buttons. Very nice!
The display is driven by a ST7735R controller ( ST7735R-specifications.pdf (2.1 MB) ), can be used in a “slow” and a “fast” write mode, and is 3.3V/5V compatible.
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.
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.

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).

However, if your application needs your screen sideways, then you’d want to rotate the screen 90 degrees, effectively changing the display from a 128×160 pixel (WxH) screen to a 160×128 pixel display. Valid values are: 0 (0 degrees), 1 (90 degrees), 2 (180 degrees) and 3 (270 degrees).

Sed porttitor neque ut ante pretium vitae malesuada nunc bibendum. Nullam aliquet ultrices massa eu hendrerit. Ut sed nisi lorem. In vestibulum purus a tortor imperdiet posuere. ");
I have already figured out how to do this for the Sainsmart 1.8" display. It would be advantageous to make this generic for all ST7735R displays with appropriate configuration in webconf.
In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.
The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.
This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.
The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.
The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:
In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.
In Part 1, we were able to obtain and display values from KX022-1020 accelerometer on the TFT LCD panel. In Part 2, we’ll show how to control the TFT monitor while reading the contents of the program!
As before, we’ll be usingSainSmart ST7735RTFT monitor. It’s a compact LCD display that can be used both with Arduino and Raspberry Pi. The monitor has a built-in microSD card slot, so it’s possible to store and load images, in addition to reading and writing data. In this tutorial, we will only try to display values on the TFT monitor.
Once you made the change, compile the unzipped “TFT 18” directory with zip again, add it as a library in Arduino (or Arduino Create) Add Library, or place it under the “libraries” directory in Arduino’s installed directory and load the library.
for (uint16_t x=0; x < tft.width; x+=6) { tft.drawRect(tft.width/2 -x/2, tft.height/2 -x/2 , x, x, color); } } void testfillrects(uint16_t color1, uint16_t color2) { tft.fillScreen(BLACK); for (uint16_t x=tft.width-1; x > 6; x-=6) {
for(uint16_tx=0;x
Next, let’s display the accelerometer values on the TFT monitor! In the case of the Sensor Evaluation Kit, basically, it’s not necessary to change the wiring on the TFT monitor side. All that is needed is to insert KX022-1020 accelerometer to the Sensor Shield.
for (uint16_t x=0; x < tft.width; x+=6) { tft.drawRect(tft.width/2 -x/2, tft.height/2 -x/2 , x, x, color); } } void testfillrects(uint16_t color1, uint16_t color2) { tft.fillScreen(BLACK); for (uint16_t x=tft.width-1; x > 6; x-=6) {
for(uint16_tx=0;x
This concludes the tutorial on how to display and graph accelerometer values using TFT LCD monitor! There are quite a few side projects we can consider developing. For example, we can combine this TFT monitor and Arduino Pro Mini to make a wristwatch featuring small games, etc. It is also possible to make a data logger using, for instance, different sensors from the Sensor Evaluation Kit.
I am sure that I have tried the microSD with the TFT. But I can"t find the "adapter" that I would have made to convert the green pinout to the regular red pinout used by red 3.3V ILI9341, ILI9163, ST7735 boards.
The TFT isn’t ‘plug & play’ with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.
-Get Kamal’s source which has the patch for ST7735R controller and the branch for the kernel that is used in 2013-02-09-wheezy-raspbian, which is 3.6.y;
If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.
If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.

... design. A dab of glue helps to keep it in place.. It certainly looks better sitting on the desk compared to a breadboard. I"ll be putting an instructable up soon to detail the software. The display is a 1.8" TFT st7735 and only costs about $7
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.
From all the Googling I"ve done, and searches on this forum and some others, I don"t seem to find any driver for this particular controller. ST7735, ST7735R and even a ST7735FB are easily found and drivers are available..
This is a short Application Note about how to use ST7735R Controller based TFT screen with RaspberryPi Universal Expansion Boardand RaspberryPi. More information about the screen can be found in the list of my Peripheral Boards.
We are using a SainSmart 4 port relay board, and connecting the 4 input lines to analog ports repurposed as digital outputs. For more information, see http://arduinotronics.blogspot.com/2013/01/working-with-sainsmart-5v-relay-board.html
