arduino 2 8 tft display supplier

In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

The sizes are 0.96” (160×80), 1.13” (240×135), 1.3” ((240×240), 1.33” (128×128), 1.54” (240×240), 1.77” (128×160), 2.0” (240×320), 2.3” (320×240), 2.4” (240×320), 2.8” (240×320), 3.2” (240×320).

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

Hi. I also got this display (off ebay). I found a contact email on the mcufriend.com website, so i emailed them, and after a few exchanges i was sent a sketch called _8347uno that makes the screen go black instead of white. i count this as some progress, however im not very knowledgeable on how the code works. perhaps somebody can use it as a basis to make a library to make these work?

i looked up 8347 and found there is are controllers with that number, and i tried the UTFT set up for the HX8347A controller with no luck, but im hoping someone with more knowledge than me can figure it out.

I am using the example file that came on a CD with my display called "Example07-ShowBMP" (as mentioned above), so I copied and pasted the pertinent lines from the "SoftwareSpi.ino" file into the "Example07-ShowBMP" and tried to run it.

I still had issues after fixing this issue with this example file. It seems the bmpReadheader(File f) function has issues with the SDFat library. If I comment out the call to that function, the bitmaps are displayed, but they are shifted to the right by about 10 pixels.

I compared the serial values that are printed between the previously mentioned NANO connected to this display with hardware SPI and default SD library compared to the exact same display and SD card connected to a MEGA and using the SDFat.h file. I am including that serial output here:

I hope to add some serial print lines and try different things and look into the SDFat library and see if I can figure out what is going on. I am also convinced the example program I am using is not very well written, as I tried to change the size of the display and found that while they made height and width variables at the top of the program, they did not use those variables inside the function to allow the different sized displays to be easily used. I"m sure the SDFat library is fine, but it is not a plug and play with this particular display"s example programs. Once I get it resolved, I intend to post better example software on the Amazon page where I bought the display. I like the display, but I must think this would annoy many customers.

I have already searched through this forum but I found out most of the 2.8"" TFT LCD problems discussed here are based on the one with a breakout board module, which can be directly plugged into Arduino UNO. While the screen I got has 34 pins, 17x2.

as a guide to interface the screen with Arduino UNO. I find out that the screen shown in the link actually has slightly different pins compare to the one I bought (Because the one is for 2.4"" TFT LCD I guess?).

So, anyone has deal with this kind of 2.8"" touch screen before? What is the exact connection on this? And also on my screen, the pins MISO, MOSI, CLK, T_CS, PEN, F_CS are left unconnected.

Alibaba.com offers 391 arduino tft screen products. About 57% % of these are lcd modules, 21%% are lcd touch screen, and 5%% are integrated circuits （old）.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (8" diagonal) bright (36 white-LED backlight) and colorfu 800x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel attached on screen by default.

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).

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

For 8 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-RA8875.

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

I"ve been looking for a product for my 8-bit cpu project and I liked the look of this screen. I was impressed that the claims on the Amazon page says it works with an Arduino mega 2560, so I bought a screen and an Alegoo mega 2560. My project depends the ability to read sn SD card. I currently have an external reader, which may or may not work. However with this TFT screen great I would have a screen and an SD card reader all in one!

The product arrived very after one day. When I opened the screen display, I found the display, a DVD and a touch screen pen. I read the contents of the DVD looking for a manual. There"s a German and English user guide. Looking through I was encouraged to see the mega 2560 being used to control the screen.

Example05-ShowBMP and SDCard Exten Example can not work on MEGA2560, because SPI IO of MEGA2560 is different from that of UNO. So example need to read the SD card can not work on MEGA 2560. The result of the examples are the same as that on UNO."

So to get the screen working I bought a genuine Uno (wasn"t going to buy an Elegoo clone. Was annoyed with them at this time). The Uno arrived and yes the SD card works. The product works well with an Arduino Uno, but not a Mega 2560.

I have looked over the Amazon web page a few times and I don"t see any indication the SD card part of the screen will work with an Arduino Mega 2560. Another annoyance now is that the screen is dedicated to using the Uno. The Uno has only 1 or 2 IO pins remaining to connect to external devices,but the screen covers them over.

The software was disappointing. Quality control of the hardware drivers is lacking. The examples work, but there are compiler warnings from the hardware drivers. I looked on github for updates, but last updatesd 2018.

For me to give this product five starts, Elegoo need to provide a shield that fits between the Mega2560 board and screen and allows the SD and screen to work. Access to the 53 IO ports is required.
