mcufriend 2.8 tft lcd shield for sale

I have bought "MCUFRIEND" 2.8 tft touch lcd and controller printed on it shows "ILI9338". Example given in this library are not working except for the basic one and it don"t even work with touch examples. After searching on google found out that "MCUFRIEND_kbv" library for debug. When i run "diagnose_tft_support" it shows following output. Also added "Read reg" after first output. Please Help !!!

there are (now) a lot of 2.8" TFT Pi designs out there. I believe mine was the first, and has been around in one form or another for over a year now. I offer full support on this forum, and here is the support thread :

This note introduces a low-cost Thin Film Transistor (TFT) display to enhance the operation and usefulness of Liquid Crystal Display(LCD) devices. TFT technology controls the pixel element on the glass surface thereby greatly reducing image blurring and improving viewing angles.

The test board chosen for this exercise is the Elegoo Arduino UNO board from the corresponding Super Starter Kit. The kit already has several simple numeric and text displays. The TFT display may perhaps provide better ways to interact in applications.

The controller for the illustrated model of the TFT display is SSD1297.This information is important because the display (owing to its low cost and high popularity) has many different manufacturers who may not leverage the same controller instruction set. The specification of the controller in the coding exercises is examined in the Appendix section of this note.

Of course, the display can be mounted elsewhere and the pins connected to the Arduino directly or indirectly using, for example, a breadboard. Other components can then use the breadboard in lieu of a shield with custom connectors. Of course, without access to such anon-standard or readily available breadboard, it is impossible to illustrate this arrangement in this note.

The output from the diagnostic program, LCD_ID_reading.ino, is shown below:Read Registers on MCUFRIEND UNO shieldcontrollers either read as single 16-bite.g. the ID is at readReg(0)or as a sequence of 8-bit valuesin special locations (first is dummy)reg(0x0000) 97 97ID: ILI9320, ILI9325, ILI9335, ...reg(0x0004) 97 97 97 97Manufacturer IDreg(0x0009) 97 97 97 97 97Status Registerreg(0x000A) 97 97Get Power Modereg(0x000C) 97 97Get Pixel Formatreg(0x0061) 97 97RDID1 HX8347-Greg(0x0062) 97 97RDID2 HX8347-Greg(0x0063) 97 97RDID3 HX8347-Greg(0x0064) 97 97RDID1 HX8347-Areg(0x0065) 97 97RDID2 HX8347-Areg(0x0066) 97 97RDID3 HX8347-Areg(0x0067) 97 97RDID Himax HX8347-Areg(0x0070) 97 97Panel Himax HX8347-Areg(0x00A1) 97 97 97 97 97RD_DDB SSD1963reg(0x00B0) 97 97RGB Interface Signal Controlreg(0x00B4) 97 97Inversion Controlreg(0x00B6) 97 97 97 97 97Display Controlreg(0x00B7) 97 97Entry Mode Setreg(0x00BF) 97 97 97 97 97 97ILI9481, HX8357-Breg(0x00C0) 97 97 97 97 97 97 97 97 97Panel Controlreg(0x00C8) 97 97 97 97 97 97 97 97 97 97 97 97 97GAMMAreg(0x00CC) 97 97Panel Controlreg(0x00D0) 97 97 97Power Controlreg(0x00D2) 97 97 97 97 97NVM Readreg(0x00D3) 97 97 97 97ILI9341, ILI9488reg(0x00D4) 97 97 97 97Novatek IDreg(0x00DA) 97 97RDID1reg(0x00DB) 97 97RDID2reg(0x00DC) 97 97RDID3reg(0x00E0) 97 97 97 97 97 97 97 97 97 97 97 97 97 97 97 97GAMMA-Preg(0x00E1) 97 97 97 97 97 97 97 97 97 97 97 97 97 97 97 97GAMMA-Nreg(0x00EF) 97 97 97 97 97 97ILI9327reg(0x00F2) 97 97 97 97 97 97 97 97 97 97 97 97Adjust Control 2reg(0x00F6) 97 97 97 97Interface Control

Can this 2.8" elegoo display play video at all? I"m trying to make a unit that an older woman, in her 80"s can play a video on it, if I set it up correctly? This is for a really good cause, I desperately need help, this is super important. Helping elderly folks with modern technology is tough. But I really need it to be able to play a video off the SD card if possible. Any help would be super highly appreciated.ReplyUpvote

Hello,please post our code also ..the screen driver must be known and that info must be known in order to get these things to work correctly..you show your code and then the vid blurs..Someone needs to write a pdf teaching how ,what ,when and why concerning these screens I would gladly pay $10.00 and I am sure others would too.I have 3 different tftlcds only 1 works its for the mega and Bomer has a lib for it,I am really considering use of Nextion units from now on 4 pins easy programming but higher cost...also the small cell phone screens use spi mode and are real easy to set up and use

The program runs and nothing is displayed but a white screen. when I open the COM4 I see that when I hit the screen numbers appear to calibrate the screens position so it is registering but not showing up on the LCD. please help me before I pull all my hair out.1

I"m having issues getting this display to work on my Arduino 101 board with the libraries that are suggested - errors in compiling seem to indicate that the board type isn"t supported in the Adafruit_TFTLCD library. Here"s a representative error:

I finally got the touchscreen to work correct using your links to the libraries. Found out that this specific TFT display module uses pin 6 & 7 for touch sensor, instead of the standard 4 & 5.0

I never received a response on this, so went through the painful process of copying code from the video. It can be found here for others that might need it. Not that this has some minor changes, but is fully functional and I will continue to refine: https://github.com/siliconghost/Arduino_2.8in_TFT_wSD

2)When EOL happens,usually we will get notification from original manufacturer 3-6 months in advance. We prepare another LCD brand solution as replacement for you or recommend you to do last buy if your annual quantity is small or even tool up a new LCD panel if your annual quantity is big.

I have to make a school project involving an Arduino Uno with a 2.8" TFT LCD touch screen display. in my project, i have to connect it such that the display is linked to a LED push button that receive inputs and react accordingly, as well as a speaker. However, my TFT LCD display fits perfectly into my Arduino Uno meaning i have no more input slots to connect to my push buttons nor my speaker. initially i found a different TFT display that came with an Arduino Shield that made life simplier however those products were not being shipped to my country:(

i am unable to use an Arduino Mega either since the SD socker in my TFT LCD display does not support the Arduino Mega. i understand in order to have my tft lcd display and my LED buttons and speaker to work i can have 2 Arduino Unos and have them work in Master-Slave however i would still need to have a common ground for both arduinos first and connect them which i am unable to do so since there"s simply no way i can fit a jumper cable in there once i place my tft lcd display on the arduino uno. Please help guys:(

Normally we show example of real-time reading things like DHT11 on monochrome LCD displays. We can graph that information. Graphing With Arduino on TFT LCD Color Display Probably a Needed Matter to Many Users. Graphing Can Become Difficult On Display With Less Known Drivers. Previously we have talked around MCUFRIEND TFT LCD Calculator. That one had problem with working codes. There are worse displays which are sold. Worse in the sense – most of the Arduino users need some easy working library which works with most common matters. This guide discuss some of the basic matters for the displays which use Elegoo Libraries (Adafruit Industries) and MCUFRIEND TFT LCD. The logic will be same for all similar displays but some tweaks needed for the others to make graph in proper orientation.

There are 3 main matters in the coding part – setting up graphing, reading value like temperature from DHT11 sensor, draw the graph. Unfortunately for practical purpose, you need to use board like Arduino Mega. Connecting DH11 with Arduino UNO is difficult as it occupies the whole board covering all pins. We are not always using the card reader but essentially it is difficult use the unused pins on Arduino UNO with such shield display.

Basically I purchased one Elegoo 2.8′ TFT LCD and was searching for graphing for some other reason. You can directly open this link to use in Arduino Web Editor. To use the same code on other boards, you need to modify some parts like :

In next article, we will see how we can graph values read by LDR on MCUFRIEND display. That is hopefully will be simple. Although with my model of MCUFRIEND TFT LCD, it not going to be easy to make it properly oriented.

Hi, the schematic of this display is similar to mine and shows at header JP3 the Arduino Uno power header. Do you know if this 3.3V on this TFT shield/board is actual used. In the schematic it is shown as a label but is not connected to any one. It can not be connected to schematic internal 3.3V coming form the regulator because this would mean a short cut between two power sources. My feeling is that is and auxiliary power source for a non installed chip that I have on my board. Since that chip is not installed it looks like its not needed.

I ask this because I want to use this TFT with a Arduino nano which doesn’t have much 3.3v power on that pin. If it is used i need to implement and extra 3.3V regulator, if not its not needed.
