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

You can google for "TFT Module Schematic" and look at the images. You may find something similar. Clearly the pins broken out to data lines will not be candidates for the back light(s).

I did more or less the same thing for a different screen and was fortunate to find a pinout diagram. [solved] 3.5" TFT LCD Shield Backlight control ? - Displays - Arduino Forum

Now I am testing Back Lit. I found that my guess was wrong. The pin BL is not LED anode, but Low level on. I used a multimeter to check that the current from BL pin to ground is 2.5mA. So I now guess BL is not a signal pin but a pull down LED power pin, sinking 2.5 mA to switch on Back Lit LED. Anyway, I am glad that now I have a huge size 2.8" white LED! :)

Now I have loaded the kernel module fbtft_device name = ici9341. I can also listed the module. But I found that I made another wrong guess - four SPI signal wires are not enough, I also need 3 more GPIO wires RST, DC (select Data or Command mode), and BL (back lit), ... :(

My ICI9341 SPI cable V2.0 does not work, because the signals Touch LCD RST and RS (Register Select) or DC (Data Command Mode Select) are missing. So I have assembled V3.0.

I just found that my Rpi3B+ with Raspbian 2019Apr version already has a fbtft kernel driver which sadly is not the ici I ma using. So I need to build a driver myself. I found the following driver tutorial but found it very tedious. Trying it this Sunday afternoon might corrupt my Rpi OS. So I decided to stall this part of project for a couple of days, to allow me to go through slowly the tutorial.

It is the cheap TFT display you will get from ebay. There are serveral models using different drivers - mine uses LGDP4535 - that look like the picture above.

It’s really stupid with these Icons. It looks like the touch screen of a cheap-crappy-chinese phone. However, I managed to remove that and leave a clean TFT screen. It is quite easy. The touch screen made of a piece of glass that sticks to the underneath screen using sticky tape instead of bezel frame. Just lift the glass up and it comes out. But one problem: you have to use double side sticky tape to replace the tape you take out. For me, I will use silicon to stick the touch screen to the TFT screen. Mean while, I use clear sticky tape to stick the touchy-glass to the whole thing.

I searched google and tried several libraries and sample codes but non-success, all I could do is get the LCD driver chip id: 0×4535 and a blank white screen until I found a thread on forum.arduino.cc for the same TFT LCD shield brand name www.mcufriend.com.

Other people on arduino have the exactly look alike LCD shield like mine, but it comes with the chip ST7781, ST7783 or HX8347… which someone already wrote libraries for them.

When I try the touch screen, I find out that the default TouchScreen has the Zero point (0,0) located in the bottom-right corner not top-left like the LCD. I added rotation ability to the TouchScreen library and renamed it to zTouchScreen.

There are other ways to calibrate this touch-screen like this link or use the sketch at the end of this post. Thanks Nick for the sketch that helps a lot in calibration.

Width and Height are the in the default orientation, for this shield it is rotate = 0 and and width = 240, height = 320. If you want to rotate the screen 90 degree, just put rotate = 1, but width and height still the same (240 and 320).

here is how to calibrate the touch screen http://www.seeedstudio.com/wiki/2.8′’_TFT_Touch_Shield_V1.0#How_to_calibrate_the_touch_screen_.3F

p.x = tft.width()-(map(p.x, TS_MINX, TS_MAXX, tft.width(), 0));

p.y = tft.height()-(map(p.y, TS_MINY, TS_MAXY, tft.height(), 0));

tft.fillCircle(A.x, A.y, 10, GREEN); // draw a filled circle

You are my new god! I have been working for days on finding a library that would bring my LCD display to life. I finally got the chip identified to LGDP4535 and Google led me to you. Now it works perfectly even the reverse touch is fixes. Thank you very much for spending the time solving this an sharring it with us.

You are a life saver. Got this LCD from amazon and got it working with your library. There is still one thing left unsolved -the touch screen part. There is no touch screen library in your attached code and I tried many versions from online. Never can draw anything with paint sketch. Can you elaborate?

Thank you for uploading the library, Ceez. The touch screen part is still not working. All the samples in your library displayed fine. It just does not respond to touching (such as Paint and Keypad). After uploading the samples from TouchScreen library, some x,y,pressure display and scrolls in Monitor. Is this a bad LCD or something else I am missing? any thoughts?

We need SPI (D11, D12, D13 of Uno) to communicate with SD card and sometime with the LCD TFT, but with this shield it uses 8-bit bus interface (LCD_D0 - LCD_D7) instead of SPI. That is why only LCD works but SD card doesn’t. But I think touchscreen should work too, because it needs 2 digital pins pull up to Vcc and 2 analog pins to get read of x-axis, y-axis of touch-point.

Thank you for your quick response. Yeah I didn’t have high hopes for the touchscreen. The SD would be nice though… I guess I will see about tracing out the holes on CON1 for being able to just breadboard with.

The weird thing I noticed is digital pin 11 shows activity on touchscreen presses. Which is labeled as part of the SD spi pins. I saw a bit from Adafruit about some of their shields sharing SPI for the touchscreen and SD. Still have some messing around to do then.

Great Job! I just ordered this PCB. Looks and fits like an Arduino shield, but there are no pictures to verify this. I have also read that this chipset/LCD requires 3.3 VDC. Is it safe to plug it into an Uno or a Leonardo?

I have found a way to make the SD card work with an Arduino Mega. The problem is, that the shield is for an UNO, and the Mega uses other pins for the SD card.

The calibration code that Nick provided returned the Min and Max values swapped. Once that was fixed everything works beautifully. The shield really does not like MEGA.

SD card using SPI (hardware SPI - D11, D12, D13 on Uno) to transfer data and some LCD TFT displays use SPI too, but this shield it uses 8-bit bus interface (LCD_D0 - LCD_D7) instead of SPI. That is why only LCD works but SD card doesn’t.

Thanks for the info, Ceez. This is a tough one. I follow instruction here https://learn.adafruit.com/2-8-tft-touch-shield/bitmaps, more here (https://www.arduino.cc/en/Reference/SDCardNotes), and Adafruit’s SD library (https://github.com/adafruit/SD) with soft SPI. Still no luck. should work though. Guildo, Please post back if you had a better luck.
