Thank you so much, I was close to quit trying to make this hmi work, but now it is done

UPDATE: New Driver with clean main.c and with deactivated Lottie

Did You prepare also something for Arduino on ESP32-S3?

hello, i face partition error do you have any idea how to solve it ?

Hello, Can you make a video that show how to connect through UART interface with this LCD?\Thanks,

I think the Espressif Eclipse IDE is the perfect fit for me.. Arduino IDE is too simple, it doesn't seem to like jtag-debugging a FreeRTOS project VS Code/PlatformIO is very confusing, way too many scripts, json files configuration, buttons everywhere, I think it's a mess. One question, whenever I building any of the sample projects from the list of templates, I always get a popup warning "Low Application Partition Size" : "Less than 30% of application partition size is free (275,072 of 1,048,576 bytes)" +--------------------------------------------------------------------------------+ | Memory Type/Section | Used [bytes] | Used [%] | Remain [bytes] | Total [bytes] | |---------------------+--------------+----------+----------------+---------------| | Flash Code | 582002 | 6.94 | 7806574 | 8388576 | | .text | 582002 | 6.94 | | | | DRAM | 107608 | 33.49 | 213688 | 321296 | | .text | 78798 | 24.53 | | | | .bss | 16992 | 5.29 | | | | .data | 11768 | 3.66 | | | | Flash Data | 100824 | 1.2 | 8287752 | 8388576 | | .rodata | 100568 | 1.2 | | | | .appdesc | 256 | 0.0 | | | | RTC SLOW | 536 | 6.54 | 7656 | 8192 | | .rtc_reserved | 24 | 0.29 | | | +--------------------------------------------------------------------------------+ The programs seem to work, or at least it downloads to the ESP32C3 device and can be stepped thru.. however, why do I get this error on the example projects, and what's a good way to fix it? I'm concerned that I will run out of space if I adding code (like MicroPython) to any of the examples! BTW, do you use MicroPython on the ESP32 IDE

thank you so much !

thank you

Massively appreciate this video - there's not many resources on this setup. I have created my GUI in Squareline, imported it into Espressif IDE and built successfully. It then ran to the board successfully but I now just have a blank black screen. I am getting a response in the Terminal stating "Hello World" so it must have transferred correctly as I can see in Main.c that that is what its meant to do.

C'est impressionnant , tout a fonctionner de mon coté en suivant votre vidéo. Un gros merci.

I have managed to rotate the screen by copying several files from default "08_lvgl_Porting" example folder (waveshare_rgb_lcd_port.h, waveshare_rgb_lcd_port.c, lvgl_port.h, lvgl_port.c and sdkconfig) to the exported Sqareline studio template folder, I have changed the rotation to 90 grades in the sdkconfig, and it works. There is still one question: do have any shadow-like artifacts on the imported png files? They are seen on dark background, and also seen on Sqareline Studio stock buttons with shadows (glow) effect, or when just pressing the button. On PNG images the shadow artifacts are constant. It is interesting, that these shadow artifacts are in one direction only, in landscape orientation they are on the right of the images, and in portrait orientation they are below the images. Can not understand, what can be the reason.

Thank you for the video and Squareline studio files, I managed to make the project successfully for the 4.3B version of Waveshare ESP32 LCD. One question, that I am struggling at the moment: did you manage to rotate the screen from landscape to portrait orientation? Changing rotation in Squareline Studio does not help, and changing the resolution in main.c through "#define EXAMPLE_LCD_H_RES" & "#define EXAMPLE_LCD_V_RES" just gives flickering screen with lines and inverted colors.

I did everything, everything passed and the code was recorded without problems, but it's just a black screen, no apps

Thank you, bro! From your previous video, I tried to install and replicate it. However, I mistakenly installed the IDF instead of the IDE. After realizing it, I revisited your video and successfully completed the GUI setup. As I mentioned in your last video comment, it would be super helpful if you could teach us how to exchange data between an external microcontroller (MC) and the ESP device to display data and control actions, like sending data back to the external MC. An example with a button, LED, and an external MC would be perfect because there are very few tutorials on using Espressif IDE for such tasks. Your teaching style is clear, and it's easy to follow. Looking forward to it!

Una duda, sabes como detectar el botton, tengo conocido de que el botton es ui_button2 pero no se como detectarlo, no me se las funciones, solo quisiera tocar el boton y mostrar un log de que se pico

Muchas gracias, dure un dia entero queriendo cargar interfaz

Amazing job Bro! It looks so simple with your explanations

hi, i made a video for those who want to know how to install the ESPRESSIF IDE -> ua-cam.com/video/726Hj0VDrk8/v-deo.html

please use open source software like eez studio

You did what Waveshare should have done! Excellent tutorial!

Great tutorial, after spend many hours with Arduino IDE, your metod works very well. Waiting for next videos. But i have question, i saw that after adding some images to LVGL the ESP IDE shows that bin file is too large. Does the ext flash memeory and psram are used while compiling?

Can you please explain how to change label text or action to push button in Espressif IDE? Some basics. Thank you

I can build the project without errors but can’t seem to load the the display? Do I need to hold boot button or something?

good video but could you tell me how you managed to get an image to display (Your short) i've managed to load a project onto my display as shown here but as soon as i try to upload any images, i only get a black screen...

Now i am trying to decide what to buy and you really helped a looot. So i can use this one with adafruit I2C sensors and also make a complex project?

Thank you!! Fantastic tutorial got it up and running in no time. You're a legend.

Thanks a lot bro. how to get data from external MC to display and vice versa? some example with button, led and external MC would be helpful withit.

How easy would it be to communicate the touch screen inputs to a mega 2560 controlling a bunch of motors??

Really appreciate the walkthrough! Very clear. I've been wrestling with getting this display to work with Arduino IDE. Have you tried this? I can't seem to find any help and the waveshare wiki walkthrough simply does not work.

can i use these same settings for waveshare lcd 4.3?

I have a question about the driver. Did you create it? Or where does it come from?

Excelente, gracias por el tutorial, me funcionó a la perfección!

Hello, I want to use the screen in portrait mode, so I need to rotate it by 90 degrees. What should I do for this? I am using the code you shared on GitHub.

In the Arduino IDE settings, how should I set up the libraries I'm using? Because right now I'm encountering an issue where the image cuts off by itself. Thank you in advance.

What expressif idf do you use? Do you try arduino? I try lvgl_Porting example but don't work fine screen have weird behavior (images cuts and misplaced)

Hello, can you make a video showing how to use the esp to update values on screen, maybe using the onscreen slider

Hi! I would like to ask you why in my square line studio boards folder I don't have any espressif folder where I can insert the waveshare screen driver. Can someone help me? Thanks a lot.

I believe this video is very helpful for the ESP32 GUI project and is also beneficial for Waveshare's ESP32 7-inch users. It's impressive to see a creator like you put so much effort into making this video. Waveshare should offer you the best product discounts. If you have any ideas about incorporating other new Waveshare products in your future videos, I will definitely provide you with price support!

Thank you for this very valuable video that has helped me a lot in advancing my project. Keep up the good work. Thank you.

Here's the English translation: Hello, I just bought the same device, but I can't display anything from SquareLine studio. Can you help me? Thank you in advance. Alexis (I'm in France)

When you want to know how I make it work subscribe and stay tuned, I am going to make a video about it!

Looks great! Always wanted to start a project like this
