Hi guys, welcome to today’s tutorial. Today, we will look on how to use the 1.8″ ST7735  colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored display or something bigger with additional features, that’s where the 1.8″ ST7735 TFT display comes in.

The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.

The schematics for this project is fairly easy as the only thing we will be connecting to the Arduino is the display. Connect the display to the Arduino as shown in the schematics below.

Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:

We will use two example sketches to demonstrate the use of the ST7735 TFT display. The first example is the lightweight TFT Display text example sketch from the Adafruit TFT examples. It can be accessed by going to examples -> TFT -> Arduino -> TFTDisplaytext. This example displays the analog value of pin A0 on the display. It is one of the easiest examples that can be used to demonstrate the ability of this display.

The second example is the graphics test example from the more capable and heavier Adafruit ST7735 Arduino library. I will explain this particular example as it features the use of the display for diverse purposes including the display of text and “animated” graphics. With the Adafruit ST7735 library installed, this example can be accessed by going to examples -> Adafruit ST7735 library -> graphics test.

The first thing, as usual, is to include the libraries to be used after which we declare the pins on the Arduino to which our LCD pins are connected to. We also make a slight change to the code setting reset pin as pin 8 and DC pin as pin 9 to match our schematics.

Next, we create an object of the library with the pins to which the LCD is connected on the Arduino as parameters. There are two options for this, feel free to choose the most preferred.

Next, we move to the void setup function where we initialize the screen and call different test functions to display certain texts or images.  These functions can be edited to display what you want based on your project needs.

testdrawtext("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Curabitur adipiscing ante sed nibh tincidunt feugiat. Maecenas enim massa, fringilla sed malesuada et, malesuada sit amet turpis. 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. ", ST7735_WHITE);

All the functions called under the void setup function, perform different functions, some draw lines, some, boxes and text with different font, color and size and they can all be edited to do what your project needs.

The complete code for this is available under the libraries example on the Arduino IDE. Don’t forget to change the DC and the RESET pin configuration in the code to match the schematics.

Uploading the code to the Arduino board brings a flash of different shapes and text with different colors on the display. I captured one and its shown in the image below.

That’s it for this tutorial guys, what interesting thing are you going to build with this display? Let’s get the conversation started. Feel free to reach me via the comment section if you have any questions as regards this project.

The SparkFun 1.8" (128x160) TFT LCD Breakout Board is a versatile, colorful, and easy way to experiment with graphics or create a user interface for your project. With a 4-wire SPI interface and microSD card holder, you can use this breakout to easily add visual display/interface capabilities to a project as well as providing all the storage you might need for multimedia files.

To get started with this breakout, you will need an Arduino compatible microcontroller of your choice - it is recommended to use something with extra RAM like the SparkFun Thing Plus. The breakout can be powered with either 5 V or 3.3 V.

The microSD card holder is connected to the same SPI bus as the display which keeps the required pin count low and exists to relieve the burden from your microcontroller"s poor memory due to having to store hundreds of images of cats, or really whatever you want to keep there.

I had an application where I needed the LCD display to be separate from the Arduino (Wemos D1). This let me run a ribbon cable from the panel to behind where the arduino was mounted.

I made the Adafruit 1.8" TFT with the ST7735 using SPI work on my uC32. While I wasn"t able to make it work on my own Uno32, it works out-of-box on majenko"s Uno32. Much credit to majenko for picking up the pace on chipKIT-specific improvements as well as amazing advances in graphics performance on this TFT. He"s done more for it than I think anyone thought to reach for!

I will maintain major changes to ada_dspi_tft_chipKIT_v1xx.zip attached to this first post. The best way to keep current is follow the Github repository for this project. (direct link to zip) I will be adding small UI improvements to TFTDemo.ino in ST7735/examples; small tricks I learn and develop for display of info, etc.

With the chipKIT, I was able to convert the "PORT" commands from AVR-land into simple digitalWrite()s! On the AVR, the ST7735 library won"t even run with all digitalWrite()s! This TFT shield uses the standard SPI pins ( 10, 12, 13 ) and additionally 8 as a DC / RS selector. The shield draws power from the +5V pin, but you can bypass its onboard logic shifter and go all 3.3V. People programming Netduinos for these shields figured this out and were able to get faster performance. Note: soldering and more work required if you"re wanting to ditch the 5V altogether.

Digital 4 is the chip select for the SD Card (which shares the SPI pins 11,12,13). SD Card functionality not yet implemented in the Hello World code. If I get a spare moment, I"ll add the de rigueur put bitmap from SD Card onto screen. (note to self, I also need to add majenko"s png-to-bmp php script to the project)

1) The AVR has delays added in the code and also had to use direct PORT accesses to twiddle pins 8 and 10 (DC and SS/CS) quickly enough to perform operations.

2) The first port converting everything to just using digitalWrite() in chipKIT resulted in performance slightly slower than using hardware SPI in Arduino. Once the delays were removed, WOW! Much faster than Arduino + HW SPI.

3) While I didn"t bother with the software SPI implementation of the Adafruit class, majenko worked that into the code with version 1.05 via shiftOut(). On AVR, software SPI was slow enough, you could watch the pixels draw one by one.

5) When using tft.print(), it actually erases the previous pixels where characters were. In the codebase we drew from, the background pixels of each character wouldn"t clear, so overwriting the same place would ultimately result in solid blob. Now, new text overwrites old with the background.
