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

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.

RFM1040G-AWH-LNN is a 10.4-inch, IPS TFT LCD module with transmissive mode. The module features wide viewing angle (80/80/80/80) thanks to the IPS panel which is one of the most popular techniques on the market now. It also features high brightness, high contrast and wide temperature , providing brightness 1000 cd/m2, contrast ratio (typical value) 1,000:1, Works within temperature range from-30 to +80℃, Storage Temperature covers from-30 to +80℃.

The module dimension is 230x180.2 mm; active area 210.432x157.824 mm. The resolution is 1024x768 pixels and the aspect ratio is 4:3. This is a high brightness and wide temperature TFT display module supports LVDS Interface (Low Voltage Differential Signaling). LCM voltage ranges from 3V-3.6V ; typical value is 3.3V.

RFS520Q-EZW-DBN is one of the models in our Q series--- 5.2-inch bar type TFT-LCD display module with controller board. The resolution of this module is 480 x 128pixels, and it has 4 screw holes & metal frame allowing for quick mounting. We use O-Film on the surface of this module to make viewing angle wider. The Q series mainly uses IC SSD1963. TFT modules of this series are all characterized by 36-pin MCU 8080 8/16-bit pin define, and the 8/16-bit 6800 pin define interface can be selected through Jump. Compared to the P series, functions of Q series are simple and pricing is relatively lower.

It is possible to connect this LCD TFT screen to the raspberry 3 model B please ? I don’t understand the schematic for SPI connection. Any help is welcome thank you.

Thank you very much again for all your explanations. I think at this time, GPIO9 -> LCD_RD , GPIO10 -> LCD_WR, GPIO8 -> LCD_CSbut for RESET and RS (Register Select ?) no definition on pinout shematic for the raspberry. Maybe these pins can be any pin gpio (declared in the driver source file?) raspberry pinout – Ephemeral

@Ephemeral I googled more touch LCD user guides and found all of them similar. So I have drafted a basic wiring diagram as updated. I think you can find the SPI signal lines at the Arduino shield plug CON 1, and one more CS signal line for micro SD card at the bottom side of the PCB. (Main SPI line are shared between LCD and sd card。） I could not find any BL line in your board. Perhaps your board has no back lit. Or you can try searching for it. I am going to gym then supper. See you late evening or tomorrow. Good luck! – tlfong01

Ah, let us consider one device at a time. A SPI operation is almost always write and read at the same time, sort of mouth talking and ears listening at the same time. So it is full duplex, if you wish to use this term half/full duplex. Same for SD card, you write and read at the same time. Now you can read a byte from LCD and then write the byte to SD. But this has nothing to do with half or full duplex, I think, not very sure, again. You need to wiki for SPI, and also google Rpi newbit tutorials on SPI and I2C etc, to clarify. – tlfong01

Yes, I agree. If you cannot guess the meaning of terms BL = Back Lit, and LEDA, LEDK mean Anode and Cathode, then it is very difficult to do it all by yourself. But then if you read AdaFruit’s newbie tutorials on touch LCD, you might find things not that difficult. Or if you search Amazon’s touch LCD for Rpi, you might also find it easy. Your problem is now you want to change an Arduino shield to Rpi compatible, that is indeed very difficult. Suggestion: watch what I do this weekend, then decide to give up for now and come back later, after learning SPI basics. – tlfong01

Ah, you only need 4 wires for the LCD – CLK, MOSI, MISO, CS. The 5th wire is CS for the SD card. So actually we don’t need to bother the SD card, or even the back lit, just play with LCD to start with. As I said, you can just sit back, do nothing and watch how do I test the very basic SPI thing over the weekend, … – tlfong01

Il display LCD TFT da 2,8 pollici è stato ricevuto dagli Stati Uniti (costa orientale) 20 giorni dopo aver effettuato l"ordine. Sono soddisfatto della rapida elaborazione del mio ordine e dell"eccellente tempo di consegna. Questo è il secondo display che ho ordinato in quanto il primo è stato danneggiato durante la spedizione e non ha funzionato correttamente. Il servizio clienti di Banggood si è prontamente occupato di questo problema, quindi ordino la seconda unità. Ho testato il display e tutto ha funzionato bene. L"unica cosa negativa che posso riferire è che l"imballaggio per la spedizione negli Stati Uniti era assolutamente terribile!!! Non c"era protezione per i perni di contatto, nessuna protezione per il display in vetro. Sono rimasto sorpreso che non sia stato danneggiato durante la spedizione. Il reparto spedizioni Banggood deve fare meglio! Altrimenti, sono soddisfatto del mio acquisto.

The 2.8 inch TFT LCD Display was received U.S.A (East coast) 20 days after I placed the order. I am pleased with the fast processing of my order and the excellent delivery time. The display was exactly as described in the Banggood web site ad. This is second display I ordered as the first was damaged in shipping and did not work correctly. Banggood customer service promptly took care of this problem so I order the second unit. I tested the display and everything worked good. The only thing negative I can report is that the packaging for shipment to USA was absolutely terrible!!! There was no protection for the contact pins, no protection for the glass display. It was simply placed in a thin, plastic bag. I was surprised that it was not damaged during shipment. Banggood shipping department needs to do better! Otherwise, I am happy with my purchase.
