The example in this video compikes, uploads and runs, but the display is solid white. The output from the touch is also just pegged at z 4000 odd and x&y stuck at zero.... They move a bit when I touch it but y stays at zero

Best video explaining this! Been searching for this for ages! Thx!

I saw this video just at the point where I was moving my TFT display from Arduino UNO, to a faster, more memory MCU, since I wanted to add an SD card. Good timing!

Thank you very much for your video! All the guides for similar displays assume the touchscreen's SPI is connected to the display's SPI, and so the only wire you need is the T_CS wire.

All very helpful. I wired everything up as all the diagrams that I found, modified my TFT_eSPI setup file with the right settings, turned on and nothing. After a while, I tried following your instructions to the letter, wire colours and all and it worked, even though everything I had done was exactly what you did, though I used an orange wire for CLK and a green for data, so maybe that was it. (Only kidding, I suspect that I've got a duff wire or a duff connection on my breadboard), but hey, thanks. Forget TFT_Meters, the TFT_Matrix example is super!

Magnificent guide - I now have the Display section up. Didn't work first time - tried in Arduino 2.0.0 rc9.4 - lots of critical errors compiling - updated library, boards etc still failed Using ESP32 Wemos Lolin32 and 2.8" ILI9341 TFT LCD. errors like undefined min(_h,_w) etc, got the latest tft_eSPI from GIT hub, same no matter what example I tried. So I deleted all my arduino installations, and folders, Libraries etc. Then installed fresh IDE 2.0.0 Rc9.4, added ESP 32 boards , added tft_eSPI from the IDE 2.4.72, edited the User_Setup.h file as advised, compiled with a few warnings about the Changed pin assignments - but no errors, Uploaded - and I'm a happy man! many happy displays.

Great presentation! I did run into a minor problem with the Meters script, was getting 6 warnings "ISO C++ forbids converting a string constant to 'char*' " and pointed to 6 lines (44-49) in void setup. Although the script compiled and loaded fine and the meters displayed beautifully on my display, I still did not like having those warnings. Did a little research and learned that Warnings usually mean that your program may or may not work. Those 6 lines called a function (plotLinear() with three parameters, the first of which was "A0" thru "A5". Located the function void plotLinear(char *label, int x, int y) and changed it to void plotLinear(const char *label, int x, int y) and the warnings disappeared. Script compiles and loads and runs just fine.

Thanks for your feedback. Sorry about that, Amazon can be not so good as it shows it does touch in the pictures (you can see the connections), have you been sent one that doesn't match the images? You should be able to get it swapped if yours doesn't have the connections as it definitely shows them

I would recommend connecting touch cs to screen cs so you can keep pin 21 for i2c as for instance a bmp pressure sensor will spam the touch with input. Remember to change #define TOUCH_CS. Thanks for the project but i think it needs wiring diagrams.

@JayUnderCover

Жыл бұрын

Is this possible because the touch controller is only sending data to the esp32, and the display controller is only receiving data from the ESP32. So they can technically run at the same time anyway? Does this speed things up so the display doesn't lag behind the touch input?

@XTronical

Жыл бұрын

I'd have to Check but as long as the touch controller waits until the esp32 is ready to receive data after generating its interrupt then should be OK. But would have to examine library's. As if esp32 half way through sending data to screen and starts servicing the touch then could cause corruption. The potential is there, I just haven't looked how the library's work

If you take a look at the sources of Bodmer's lib you can see that in some cases he is pulsing the chip select within a method. But in your code it looks like you are wrapping the chip select enable/disable in front of/after the method calls on the lib. Doesn't this affect operation? Or are the ili displays not dependent on these pulsings? I was thinking about replacing the esp's gpio chip select with a gpio expander for all cs lines but just have an mcp23017 (i2c) at home atm which is ok as i am not relying on high update rates. A mcp23s17 (spi) would speed up operation quite a bit though.

Thanks so much for this video! I've got a question. These display boards have a jumper "J1" for selecting the voltage. In your case for the ESP32, did you need to short this jumper "J1"? Just want to confirm before I do something stupid with my board...

@XTronical

4 жыл бұрын

Yes, short the jumper if using ESP32, leave alone (how they come by default) if using Arduino. Nothing bad happens either way for ESP32 apart from it may not work if you do not short it. Mine worked and then stopped when I added one more component to the project. For Arduino it may break the screen if you short it so leave un-shorted.

Great video, but when I try to display the image, I only see a small portion of it, whether it's with your images or mine. Any ideas?

I got Compilation error: no matching function for call to 'min(uint16_t&, uint32_t)'. Fixed it by changing min() function to jpg_min().

Hello, nice. Just put this at the beginning of your sketch: #define min_ (a,b) ((a)(b)?(a):(b))

hi there is there a big display for esp32 available like the one used in this video but it is not touch screen but a simple diplay?

Sir great video but is it possible to play continuous video on it?

@XTronical

It's technically possible but video would need to be uncompressed and only run around 12 fps. You would need to store this internally as well for speed so you'd only get maybe 3 secs of video.

Hi! Do you kno if is possible to integrate this lib with a 4' inch display? I've tested with a ILI9488 spi display, but like 30% of the display didn't show anything, I mean were blank, just the others 70%. I use a resolution of: 480 × 320. Thanks

Thank you very much! I was struggling so bad with my ILI9341. Thanks to you I managed to edit the user_setup.h so it works. The SD-Card won't work, but I guess thats due to the lack of connections on my expansionboard. I've ordered this bundle "Esp32 arduino wifi & bluetooth 2.8 "240*320 smart display bildschirm lcd tft modul mit touch ESP-WROOM-32" from aliexpress and was hopping, that all connections on the ILI9341 were lead to one side. One question: How do you delete the touch-calibration? On the first start after uploading the sketch, the touchscreen had quite a delay and so I've touched the same corner twice...🤦 Now "touch corners as indicated" shows again, but neither my finger nor the pen works. Uploading the sketch again didn't help

Is there a video on 3.5" TFT LCD ILI9486 with ESP32 board?

Ensure you are using the same version of the library as in the video. As it has been updated since it was made and I think broke some things

I'm doing this on an ILI9488. I got the meters demo to work, but can't read from the SD card. ("Card Mount Failed.") There is an ominous warning next to the ILI9488 option in the User_Setup.h file about not connecting SDO and MISO to same SPI bus, which is Greek to me, but might be the problem? EDIT: Nevermind, got it to work. Problem was my bad soldering. Works with Bodmer's test script, still can't get your code to automatically detect and display jpegs. I'll figure it out soon enough though. Thanks!

Yes, just connect it to an output pin instead of vcc. Setting pin high will turn it on, low off. You could even use pcm to give varying brightness. Arduino's and esp32 outputs can cope with the current required, although you could measure it first if you wanted to be doubly sure.
