arduino oscilloscope tft lcd pricelist

The 320x240 2.4 inch TFT LCD shield with touch panel has only A5, TXD and RXD free if you leave the SD card interface. Assuming that the A5 is an analog input, the remaining TXD and RXD are internally connected for downloading programs from USB, so I don"t want to use them as much as possible. For the time being, you can check the operation using only A5, but that alone is boring. I want to make the best use of software that assumes 2CH.

Some Arduino UNO compatible machines that use the QFP package for the CPU have A6 and A7 through holes. So use them to assign A6 for CH1 A/D input and A7 for CH2 A/D. Thus, it can be a 2-channel oscilloscope. Furthermore, if you make a UNO-like board with Arduino Nano or Pro Mini using a shield board and do not wire the SD card terminal, you can use D10-D13, so you can use it for judgment such as DC/AC selection.

I wanted to use the screen almost fully for the waveform, so if I set it to 10 horizontal scales and 8 vertical scales, it will be 300x240 with 30 dots/scale, and 20 dots left in the horizontal direction. The 20 dot width on the right side has a button area that connects to the off-screen icon. The LCD shield I got has an icon outside the display screen, and the detection range of the touch sensor has expanded to that extent. Maybe it"s for old smartphones, but it may be hard to get now. You can operate it by touching this button area, icon, or character display position.

There are so many variations of the 320x240 2.4 inch TFT LCD shield, you may have to adjust the controller ID and pinout of the touch sensors. The controller of My TFT LCD shield wasn"t popular ILI9341.

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:

The display demand for every project is unique, a project may require just a simple, single character OLED display, while another project may require something bigger, all based on the function the display is to perform. For this reason, as a maker or electronics hobbyist, anyone needs to know how to work with as many displays as possible, that’s why today, we will take a look at how to use the super cheap, 3.2″ color TFT display with Arduino.

For this tutorial, we will use the 3.2″ TFT display from banggood. The display which is based on the HX8357B LCD Controller, supports 16-wire DataBus interface and comes with 262K color at 480 x 320 resolution. The module includes an SD card socket, an SPI FLASH circuit and a 5V-3.3V power and Logic Level conversion circuit which makes it easy to use with any microcontroller that uses either 5v or 3.3v  logic voltage level. The module can be directly inserted into an Arduino Mega or Due board.

To demonstrate how the display works, we will use the UTFT LCD library for Arduino to display some images and text on the display including an animated graph. All these will show how the display could be used for something like an oscilloscope.

These components can each be bought via the links attached. The 3.2″ TFT display, as at the time I bought it was listed on the website as a 3″ display but after buying and measuring, the size of the display is 3.2″.

The display comes in a shield form, which means it can be plugged directly into the Arduino with which it is going to be used, as such, no schematic is needed. Plug the display into your Arduino Mega or Due as shown in the image below.

To achieve the goals of this tutorial, we will use a simple sample code attached to the UTFT library. The UTFT library is a library created to facilitate easy interaction between a microcontroller and several LCD displays. Unfortunately, the latest versions of the UTFT library has no support for the HX8357B LCD controller which is used to our 3.2″ TFT display. To go round this hurdle, we will be installing a previous version of the library on the Arduino IDE.

The wonderful library written by Henning Karlsen can be downloaded from the link below. The libraries are pre-built for each Arduino board so choose the right one that matches the board you are using from the link below.

Use your favorite library installation method to install the library after downloading and launch an Instance of the Arduino IDE. With the IDE opened, click on file, select examples, select UTFT then select the Display Demo or the UTFT_Demo_480x320 example.

We will attempt to do a brief explanation of the code. The code starts by setting the speed (the wait variable) at which it runs to 2000. This speed can be reduced to zero so the demo can play slowly. After this, we include the utft library and invoke the custom library for the for Arduino Due.

with that done, we proceed to the void setup() function. Under the setup() function, we initialize the LCD using the init command and we ensure the LCD display is on landscape using the set rotation function with a value of 1.

Upload the code to your Arduino board and you should see the display come up after a few minutes, displaying texts, and different other graphics. A view of the display in action is shown in the image below.

You can use either of the two Arduino boards mentioned above for this tutorial. The Arduino due is faster than the Arduino mega so it will run the code faster than the mega. For instance, on the Arduino Due, the code took 23 seconds to get to the end while on the Arduino Mega, it took 44 seconds to get to the end confirming the speed of the Due.

Sir I wasn"t referring to you. I was referring to the person who made the 8 Bit comment re: Arduino and his obvious lack of knowledge about Arduino and it"s capabilities. There were two links on the original post, the second link at the bottom of that page takes you to The "lesser" of the two displays was described in the original post as Only having an 8 Bit data bus and thus 256 colors... sounded to me as if though a person from Itead Studios was trying to "push" the more expensive of the two Itead products and that generated the energy to re read and confirm prior knowledge about parallel loading color graphic displays and that product specifically as I own one, bought it for $20.00 US

But when I plug it in and upload an arduino program, the pixels light up but it won"t do anything. I"ve tried a few example programs but none of them work.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.2" diagonal) bright (5 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6206 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.

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).

Nice board awesome price. There was some problem with the delivery at the start but when it arrived it worked like a charm. I would recommend this board if you wanted something that looked like the original Arduino Uno:)
