That's very kind, thank you

Man, thank you. This saves my day. I was sure i had done my wiring right... But the touch only works sometimes or after along while powered up. With this tweak my application works flawlessly! Big thumbs Up!

Nice info, well done, and thanks for the heads-up will save a lot of time.

My man! That was it. I've been playing with those screens on stm32 and raspberry pi for some time now, just tried to use SD card reader for the first time and the screen crashed. My guess was that the spi on both are somehow shared and I can't talk to it with two SPI on my mcu at different speeds. BUT! Then I found this, soldered the jumper and it works! BIG THANKS!

Great info, thanks for sharing

Wow! Very awesome! I'm just starting with the ESP32. And I'm now learning and having to do new things. Arduino was straight forward. But the ESP32 you gotta go a little further. But this would have made me give up. Very good to know! I just got the ILI9341 up and running with the demos. Thanks for the video!

Trying to remember but I think I've only ever used the tft screens on 3.3v boards the Due, Teensy and ESP's. Didn't even notice if there was a jumper on my display. I'm really enjoying playing with the ESP32. Keep up the good work......

Great when something helps.

Thanks for the video. To recap. The ESP32 VIN is 5VDC. I connect the 3.3 VDC (pin 16) to the IL19341 VCC pin. With this power supply arrangement, both the display and the touch screen work correctly. I have had erratic results with the SD card. Sometimes, the JPG files are displayed correctly and other times nothing is displayed. Does the SD require 5VDC? Thanks

I have the marauder installer on my esp32, I use this tft screen, but I always get a message, I don't initialize the sd card

I have also been told if you are using the SDCard on 3.3V you want to remove the resistors R1, R2, R3 as they are there to protect the SDCard from 5V SPI and will interfere with 3.3V SPI.

Really, that's interesting. Never had problems but if I do will give it a go.

These "standard"breakout boards are a bit annoying to use with 3.3V devices. Question: Is the big flat chip (U2 on the big screen) a level shifter?

@XTronical

It's the xpt2046, a touch screen controller. Had to get my magnifier out!

Do these screens have logic level conversion for the sdcard data pins in case you power them with 5V? I never used the sdcard because I don't think they do

Hey Xtronical, using our videos I have been able to fill the screen via code. i have the same display but with backlight support. aka the ST7789V driver. I updated my User setup to make it work. but now I also bridged the gap between the joints but when i insert a sd card my esp disconnects from the pc. do you have any idea as to why? P.S. having it not bridged makes it so that i cant mount an sd card

Hello, me again, sorry, the 2.4'' screen did not work so I decided to buy the 2.8'' the same as yours. Now on the serial monitor I get "Card Mount Failed", do you know what could be the problem?

Did you try the hardware mod suggested on the back of the board to basically disable the voltage regulator on the screen? Also check your size of memory card. There's a max limit, think it's 32gb, could be 16, can't quite remember. Fairly sure 32. Bigger than this and won't work. I tend to use 8gb cards. Nice and cheap.

Note as well ... not all of these have the touch control chip. Your small one doesn't. The large one does.

I'm confused here! The VCC voltage was not mentioned. I have an ESP-32 dev board. I have connected the 5V pin on the dev board to VCC on the ILI9341 board. Were you connecting 3.3V or 5V to the VCC pin on the ILI9341 board. Thanks.

May I know if two esp32 can be connected to one sd card? If so, how to connect it? Please help me know about it.

Yes, it could be done. But would require some form of communication between the two to ensure they don't access at the same time. Doable but not trivial.

Man, thanks a Lot! I was checking and rechecking all 😅! I would like to aski something: I was trying to use another esp32 gpios like: SD_CS = GPIO32 SD_MOSI = GPIO33 SD_MISO = GPIO25 SD_SCK = GPIO26 I have initialized all without any problems, but esp32 could not run the firmware after i flashed it. It's work just if I force a reboot from button dev kit. I was wondering why it's happened. If I use the default gpio communications, with SPI, works all fine.

I am using these on DUE which is 3.3v by default,should I still modify this?, the SD card does not initialize currently, while I have connected screen and SD card to SPI pins and CS 4,10 pins of DUE,and use SPI.begin(4) and for 10,but does not work.

@@XTronical it has extended SPI ,which could be initialised from setup by SPI.begin(CS), SPI ports offer 5V and gnd for the client, the TFT works on one SPI port ,but SD fails to initialize on 2nd port, there are few documents available,

uuuuuhm. Well, tried this, and when inserting an SD-Card it fried my Esp32 instantly. Lots of "brownout detector triggered" messages, and that was the last thing I heard from the device. I really have no idea why. I do get the idea of bypassing the voltage regulator if you power the screen with 3.3v anyways - still, for me it did just harm the setup. You might not have any idea or suffered from the same effect at any point?

I got a new one in the post. 2.4" with touch screen + SD. Says "V1.3" on it. different PCB layout and different (visually) screen make. It doesn't work. Spent hours debugging it. Then swapped it like for like on the breadboard for another one without touch. Worked instantly. Swap back to the new V1.3, nothing, just white screen. I suppose this is the way with these chinese modules. For every few batches of fine ones, there is a batch of garbage.

Yes, very possibly. The heart pulse sensors are also very hit and miss. Least they used to be.
