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.

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

The SD-Card needs to be FAT-16 or FAT-32 formatted, single partition, and the BMP file needs to be placed in the root (ie. not in a directory or anything like that).

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)

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work you can check my particular tutorial. Here you can download that file:

The 2.8" Arduino TFT LCD Touchscreen Module (Colour Screen) is for Arduino UNO board and Mega 2560 board or boards compatible with UNO. This module can display words, colour painting, ghaphics and pictures. This module come with a large touch screen display and build in Micro SD Card socket make it user friendly and easy to use. As a bonus, this display comes with a resistive or capacitive touchscreen attached to it , so you can detect finger presses anywhere on the screen.

It all started when I saw a SainSmart 3.2” 320 x 240 TFT LCD display with built-in display controller, touch screen controller, and SD card interface for sale on Amazon for $16. I already had an Arduino Uno on hand, so connecting these two devices seemed like a natural thing to attempt. Having never connected an LCD display to a microcontroller before, I was anxious to do so. Finding a well written driver library (see Resources) for this display put the icing on the cake, so I got to work wiring things together. In an afternoon, I wired the LCD display to the Arduino, downloaded and installed the UTFT driver on my Mac, and compiled and ran the demos that came with the driver. I was amazed at how easy this came together, and I had the basis for my personal light show running in less than a day.

After seeing the demos, I started thinking about what else I could make this LCD display do. So, I started pulling out code I had written over the years and began porting it to the Arduino Uno. First off was the Mandelbrot set. While the code worked and the results were beautiful, it took a full five minutes to generate which was okay because I wasn"t in a hurry. The long generation time was not too surprising because the Mandelbrot set requires a lot of floating point calculations which are time-consuming on any eight-bit processor.

Once you"ve gathered the required components, wiring the Uno to the LCD display is easy, though rather tedious due to the number of wires involved. A lot of wires are required because I used a 16-bit interface between the Uno and the LCD display. I chose this instead of an eight-bit or serial interface in the interest of performance.

A drawback to using the 16-bit interface with the Arduino is that it uses up every available I/O pin. This means neither the touch screen component nor the SD card interface available on the LCD display"s PCB (printed circuit board) can be used. Luckily, neither were necessary for this application.

All required connections between the Uno and the LCD display are shown in Table 1 and the LCD display connector pinout is shown in Figure 1. Take your time when doing this wiring and double-check your work when you"re finished before applying power.

As I was writing this article, I discovered SainSmart also sells an assembly consisting of an Arduino Mega2560, a shield for connecting the LCD display to the Arduino, and the same LCD display we are using here. They officially call it the SainSmart Mega2560 Board+3.2 TFT LCD Module Display+Shield Kit for Atmel Atmega AVR 16AU Atmega8U2 and it’s available from their website (see Resources). If you were to buy this assembly, you could use it without having to do any wiring at all. A minor software change (to be described shortly) is required, however, to run the Contemplator sketch on this hardware.

A major advantage to using this hardware is that there are many more I/O lines available which allow access to the touch screen controller and the SD card interface if these are important to your application. Additionally, the Mega2560 has four times the RAM (8K) and eight times the Flash (256K) which would allow many more display patterns to be developed.

The Contemplator requires two pieces of software for its operation. The first is the UTFT driver library for the LCD display and the second is the Arduino sketch I wrote called Contemplator.ino (see Resourcesand the downloads for this article).

Once you have the hardware wired up, the UTFT driver installed, and the Contemplator sketch available, you can download the sketch via the Arduino IDE and watch the magic happen. You don"t need to understand how the Contemplator sketch works in order to use and/or appreciate it.

As mentioned, a software change is required to the Contemplator.ino sketch if a SainSmart Mega2560 is used instead of an Arduino Uno. The normal instantiation of the LCD driver for an Uno is as follows:

I also wanted to make it structurally sound so it would last a long time. To this end, I epoxied four 3/4” wooden dowels (1/8” in diameter) to the top corners (component side) of the Arduino PCB. I then inserted .1” male header pins into all of the Arduino"s female headers, to which I would solder wires from the LCD display"s connector.

I then epoxied the other end of the four dowels glued to the Arduino onto the back of the LCD display"s PCB, making sure to miss all of the components and to orient the Arduino so the USB connector was opposite to the connector on the LCD display. I made sure I left enough space so I could solder to the display"s connector pins.

The cutout for the LCD display in the front panel was sized so that the actual display fit through the cutout but the display"s PCB did not. During final assembly, I put a small amount of silicon caulking onto each corner of the display"s PCB and pressed the display into the cutout. Once dried, the silicon holds the display/Arduino assembly in place, but it can easily be removed for servicing.

Finally — because the frame around the LCD is white — I cut pieces of black cardboard and glued them onto the white frame to cover it. With that, the Contemplator was complete and has been sitting on my workbench/desk ever since.

Flashing LCD displays and other blinky things are not for everyone. For me, having a personal light show on my desk is a treat. There is something neat about have a little device with its one purpose in life to continually generate images like these to calm and amaze me.

Note: There are no I/O lines left over to connect the Arduino Uno to the touch screen controller or SD card interfaces, so these aspects of the circuitry are not available.
