tft lcd arduino nano quotation

Now learning arduino tft, got a cheap 1.8 tft spi display from ebay, trying the arduino TFTDsiplayText example with potentiometer, and all my "goal" is the white screen.

Is there a difference between the NANO and MEGA that would account for ST7735 displays working on NANO and not working on MEGA? I"m using the same pins on both....

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.

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.

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:

For the last day, I"ve been trying to get the library to work with an Arduino Nano RP2040 + IL9341 SPI (https://smile.amazon.co.uk/gp/product/B07QJW73M3/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 ).

I don"t rule the fact I might be getting something wrong, but can anyone confirm they got TFT_eSPI working on an actual Arduino RP2040 (NOT the Raspberry Pico) ?

Next thing I"ll try is the Adafruit_ILI9341 library, since there are actual videos of people using that combination (AdaFruit_ILI9341 + Arduino RP2040 + SPI screen).

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 libraries from Adafruit to help us easily communicate with the LCD. The libraries include the Adafruit GFX library which can be downloaded here and the Adafruit ST7735 Library which can be downloaded here.

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.

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.

Hi guys, over the past few tutorials, we have been discussing TFT displays, how to connect and use them in Arduino projects, especially the 1.8″ Colored TFT display. In a similar way, we will look at how to use the 1.44″ TFT Display (ILI9163C) with the Arduino.

The ILI9163C based 1.44″ colored TFT Display, is a SPI protocol based display with a resolution of 128 x 128 pixels. It’s capable of displaying up to 262,000 different colors. The module can be said to be a sibling to the 1.8″ TFT display, except for the fact that it is much faster and has a better, overall cost to performance ratio when compared with the 1.8″ TFT display. Some of the features of the display are listed below;

TheTFT Display, as earlier stated, communicates with the microcontroller over SPI, thus to use it, we need to connect it to the SPI pins of the Arduino as shown in the schematics below.

Please note that the version of the display used for this tutorial is not available on fritzing which is the software used for the schematics, so follow the pin connection list below to further understand how each pin of the TFT display should be connected to the Arduino.

When connecting the display, ensure that has a voltage regulator (shown in the image below) before connecting it directly to the 5v logic level of the Arduino. This is because the display could be destroyed if the version of the display you have does not have the regulator.

In order to allow the Arduino to work with the display, we need two Arduino libraries; the sumotoy TFT ILI9163C Arduino library which can be downloaded from this link and the popular Adafruit GFX Arduino library which we have used extensively in several tutorials. Download these libraries and install them in the Arduino IDE.

For today’s tutorial, we will be using the bigtest example which is one of the example codes that comes with the sumotoy ILI9163C Arduino library to show how to use the TFT display.

The example can be opened by going to File–>Examples–>TFT_ILI9163c–>bigtest as shown in the image below. It should be noted that this will only be available after the sumotoy library has been installed.

Next, an object of the ILI9163c library named “display” was created with CS and DC parameter as inputs but due to the kind of display being used, we need to include the pin of the Arduino to which the A0 pin of the TFT display is connected which is D8.

With the libraries installed, open an instance of the Arduino IDE, open the examples as described initially, don’t forget to make the A0 pin (D8) correction to the code then upload to the Arduino board. You should see different kind of text and graphics being displayed on the screen. I captured the screen in action and its shown in the image below.

Capturing physical data in real time is always fascinating. In this project you will notonly be able to capture three fundamental physical parameters for weatherpredication viz. temperature, humidity and atmospheric pressure, but also beable to display the real time data on a LCD screen.

The twosensors used in this project are BMP-280 and DHT-11. The former senses thetemperature and atmospheric pressure whereas the later senses the relative humidity.The DHT-11 could have been done with by using BME-280 (it can measure humidityalso) instead of the BMP-280, but if the cost is taken into account then usingthe combination of sensors used here is much more economical for DIY projects.It should also be noticed that although DHT-11 is capable of sensing bothtemperature and humidity, it is used for humidity sensing only because itstemperature sensing resolution is +/-2° compared to +/-.5° for BMP-280. The heart of this project is the Arduino NANOdevelopment board. Here also the NANO board has been chosen over the masspreferred UNO because of its affordable price. A 1.44” ST7735 series TFT LCDscreen is used as the display for our project. A bigger screen has been avoidedhere so that the Arduino NANO is not overloaded.

Acombination of circuit diagram and block diagram has been provided asconveniently as possible to help the makers understand the physicalconfiguration and connection of the components. Tables for pin-out of thecomponents is also provided to make things easier. Going through the diagramand tables one will notice that the 5V and GND pins of the ICSP header onArduino NANO has been utilised for supplying power to the components along withthe on-board power and ground pins. This has been done to do away with anyadditional power source which will make the system bulky.

Coming tothe programming, in the first part an array of libraries have been included tokeep the programming short and simple. Besides the obvious ones, the Wire.h andSPI.h libraries are worth mentioning because Wire.h is the one that allows theArduino to communicate with the I2C/TWI devices such as the BMP-280 and theST7735 LCD and SPI.h provides the serial peripheral interface with the ST7735LCD. In the second part, the sensors are initialized and the layout, fontcolour etc. of the LCD are set up for displaying the data as per ourpreferences. In the final part of our programming, the output from the sensorsare obtained and displayed with a convenient delay between each reading to keepthings stable.

In theprototype, the components have been kept modular and connected using jumperwires instead of soldering. This not only allows easy troubleshooting andrepairing but also makes the assemby process hassle free. The device-case hasbeen custom 3D printed for a perfect fit for the components. The case isprovided with proper ventilation in order to expose the sensors to themeasurands and dissipate the heat generated by the system which will otherwiseinterfere with the sensing elements. The device is powered via the same type AUSB to type B mini USB used to program the Arduino. The prototype has beentested indoors at stretch for a few hours using both PC USB port and 5Vsmartphone charger as supply. The results are quite accurate compared withonline meteorological data, considering the production cost and developmenttime.

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.

According to my experence for another 2.2" LCD display with D/C Pin, I am using CD4050BE to convert the UNO pin 5v to 3.3v to fit to the TFT signal standard.

This display can be mounted on an Arduino Mega or Due. It has a fairly high resolution of 320*480 pixels and is also quite large with 3.2 inch LCD size.
