tft lcd mega shield v1 2 manufacturer

2.8" TFT Touch Shield is an Arduino / Arduino Mega compatible multicolored TFT display with a 4-wire resistive touch screen. It includes an Arduino shield compatible footprint for attachment. The TFT driver is based on professional Driver IC and with 8 bit data and 4 bit control interface.

The TFT library provides the following Application Programming Interfaces(API). The library makes use of direct access to PORT registers instead of Arduino APIs. This is to increase the speed of communication between MCU and TFT. At present, the library supports Arduino, Arduino Mega (1280 or 2560) and Seeeduino ADK Main Board compatible boards. In Mega the 8bit data port of TFT is distributed to different pins belonging to different ports. This decreases the speed of graphics drawing when compared to Arduino. The choice of port pins are purely based on Arduino / Mega port pin arrangement.

TFT Touch Shield uses the Adafruit Touch Screen Library. To understand the principle behind resistive touch screen refer External Links. In short, a 4-wire resistive touch screen provides two voltage divider each for X and Y axis. By applying proper voltages for each axis and scanning the ADC values the position of the touch can be detected. These values are always prone to noise. Hence a digital filter is used.

The Raw ADC value has to be converted to Pixel Co-ordinates. This is done with map function. This mapping changes for v0.9 and v1.0. The demo applications already takes care of this mapping.

It provides a solution for easy connection with TFT display module in 40 pins. What you need to do is just fix this shield with Arduino MEGA 2560 and TFT LCD. Very convenient and it can avoid any wrong connections. You can drive TFT LCD with UTFT and UTouch libraries in our store.

This is a versatile and Arduino/Seeeduino/Arduino Mega compatible resistive touch screen shield which can be used as display device, or sketch pad for user input/interface.

Compared with the previous version (2.8" TFT Touch Shield V1.0) we improved the screen driver with a professional chip (ILI9341) to provide the pin-saving SPI communication protocol without sacrificing the data transmission speed.

Circles isn"t the only thing our library can help you draw, we also have a lines, number, rectangle, and many more examples. Check those out as well to become a pro with the shield.

Function Description: The drawCircle function draws an empty circle with the center at the coordinates poX, and poY. The circle will be of radius r and the border color will be color. The color parameter is a 16-bit Red-Geen-Blue (RGB) integer, in the example code above the words YELLOW, CYAN, RED, and BLUE are defined as integers in the TFTv2.h file.

The TFT Touch Shield"s backlight is on by default since its control circuit is directly powered by the 5V pin. If, however, you wish to control the backlight"s on/off state using the Arduino Digital I/O pin 7, a simple modification will have to be made:

2. Notice that the ON terminal is soldered to the BACKLIGHT terminal as shown in the PCB figure below. Scrape off this connection, or use a soldering iron to remove it.

Now controlling the backlight"s state is as easy as controlling an LED, upload the following code to the Arduino board to see how to toggle the backlight every 500ms (1/2 second):

Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it"s not such fine as you think, even a little bit clunky, it"s still very cool. That is the point this is a cell phone made by ourselves.

Arduino 3.2" TFT LCD Touch shield V1 is an Arduino Mega compatible, multicolored TFT display with touch-screen and SD card socket. It is available in an Arduino MEGA shield compatible pinout for attachment. The TFT driver is based on SSD1289 with 8bit data and 4bit control interface.

The ITDB02 LCD module is work in 3.3V voltage level and it"s not compatible with Arduino MEGA pins, so we make a shield for Arduino MEGA. Now user can directly plug the ITDB02 in the shield and stand on the Arduino MEGA board.

The ITDB02 MEGA shield V1.1 supports both 16 bit mode and 8 bit mode ITDB02, you can use 2.4" or 3.2" with it. Different form the ITDB02 Arduino shield v1.2, now MEGA have enough pins for using SD card and Touch function at the same time. Not just the SD card and Touch function, there is a DS1307 on the board so you can also use the RTC function.

Now the latest ITDB02 library example is compatible with the ITDB02 shield but not the MEGA shield, you can modify the setting to make it compatible with MEGA shield.

How to use the SD card socket? The ITDB02 library has not include the functions for SD card, but we can offer you a existent filelogger library for Arduino, the pins of ITDB02 shield is compatible with this library. You can download it here: http://code.google.com/p/arduino-filelogger

As you may have read in the previous post, after careful consideration I ordered up a bunch of hardware. For the sake of this article, however, only two items will be important from that list. They are the Seeeduino Mega 2560 ADK dev board and the 2.8″ TFT Touch Shield. The problem I was experiencing was that when I plugged the 2.8″ TFT Touch Shield (“shield”) into the Seeeduino Mega 2560 ADK (“Seeeduino”), all I got was a white background with the backlight on. There was nothing else going on. I tried just about every library under the sun, every example, my own code, searching Google for solutions, etc. I saw that lots of folks were having this problem, but no one had any solutions. So, I eventually posted the problem to the Seeduino forums.

I didn’t get any replies, only more people with the same issue getting in on the action. Fortunately someone at Seeeduino took pitty on me and emailed me about it. After a couple of emails back and forth it turns out the fix is quite easy. It has to do with the Mega 2560 pinout being different than the standard arduino/seeeduino. As you can see in the image below, the regular Arduino (Uno for instance) has 14 Digital I/O pins and 6 analog input pins whereas the Mega 2560 has 54 digital I/O pins and 16 analog input pins.

Due to this difference the screen has to use different pins. Unfortunately the example sketches in the TFT library don’t tell you that you have to change anything so what you wind up with on the Mega 2560 boards is the TFT screen with a blank white background and the backlight on.

Congratulations! You’ve successfully fixed the TFT library so that you can use it with a Arduino or Seeeduino Mega 2560 or Mega 2560 ADK! On my board I tested it out and everything was great after that! Try the drawCircle sketch from the library examples once you fix this.

The graphic display coordinates and the text display coordinates of the 2.2”screen are two different coordinates systems. The origin of the graphic display coordinates begin from the centre point of the screen while that of the later one begins from the top left hand side of the screen.

* @The formal parameter size refers to the text size based on the font(6×8). Size is rounded to the integer greater than 0; if size is 1, the pixel points the font occupied will be 6×8. if it is 2, that will be 12×16. The text out of the screen cannot be displayed;

* the coordinate data of the pixel y on the y axis, values range[-128, 128] and the relationship between x and y should be: x^2 y^2<=128^2;

* the coordinate of the starting point y on the y axis, values range [-128,128] and the relationship of x and y should be: x^2 y^2<=64^2;

* the coordinate of the starting point y on the y axis, values range [-128,128] and the relationship of x and y should be: x^2 y^2<=64^2;

The function of the program: realize the refreshing of the background color of the 2.2”screen and the switching of background color among red, white and black; there are 19 common defined color in the library, and users can also customize 4-bit hexadecimal code or decimal color code (0~65535) to alter the background color of the screen.

The function of the program: draw a circle with a center point coordinate (0,0), radius 20 and green arc at the centre of the screen, and fill the circle with red.

The function of the program: draw a rectangle with a coordinate of the top left apex(-20,-20), length 40, width 40 and blue frame at the centre of the screen, and fill the rectangle with blue.

The function of the program: draw a triangle with the coordinates of the three apexes (-20, -50), (0, 0) and（50，20）and orange frame at the centre of the screen, and fill the triangle with orange.

The function of the program: draw a red line segment through the points (-64, -64) and (64, 64); taking the point (-64, 0) as the starting point, draw a white horizontal line with a width of 128; taking the point (0, -64) as the starting point, draw a white verticla line with a height of 128. The three lines meet at the centre point of the screen (0, 0).

The function of the program: taking the centre point of the 2.2”screen as the starting point(note: the graphic display coordinates and the text display coordinates are two different coordinates, the centre point of the graphic display coordinates is (64, 64) while that of the later one is (0, 0)), display a character string ”fire” with red text background box, white font and the size of the font 2 on the screen. The formal parameter size of the function to set font size tft.setTextSize (uint8_t size) should be greater than 0 and the text out of the screen cannot be displayed.

The function of the program: use the software image2lcd.exe to extract the bitmap of one image and display it on the centre part of the 2.2”screen(note: for the reason of UNO’s internal memory, the following demo cannot be accepted on UNO since the image file is too large, but it can be displayed on ESP32. So you’d better choose small image file if you want to display it on UNO. ) The parameter selection of the software is provided below.
