7" ESP32 display issue PlatformIO
Hey guys!
I need your help. I have been trying to solve that puzzle since yesterday morning, but still have some issues.
Few days ago I've got https://www.elecrow.com/esp32-display-7-inch-hmi-display-rgb-tft-lcd-touch-screen-support-lvgl.html?ann 7 inch ESP32 display. I had been using that manual: https://www.elecrow.com/wiki/index.php?title=ESP32_Display_7.0%27%27_Intelligent_Touch_Screen_Wi-Fi%26BLE_800*480_HMI_Display#Play_with_PlatformIO At the bottom of the page is "PlatformIO_7inch.zip". I downloaded it, then step by step as in instruction set up the whole project, but at the end I've got that issue:

And as I can see there are some issues in main.cpp (I hadn't changed anything. And I've got whole code from the Elecrow demo). If you know how to solve it. I will appreciate you :)
Thank you in advance

Hello @Denys ,
The compilation error message indicates that there is a problem in compiling the Arduino_GFX library. You can check what version your GFX library is. If it is version 1.3.0 or above, you need to modify the screen configuration.
If it is not for the above reasons, you can refer to this post:
Hello, thank you for offering your advice!
I just checked my version and it was the same as needed. I've read the post you sent me, but I'm using PlatformIO with VSCode but not Arduino IDE.
Here below is my platform.ini

I've added this
because my IDE was unable to find sdkconfig.h
Except that I've tried different versions of "GFX lib for Arduino" 1.2.8/1.3.5/1.4.0 even with code you sent me above, but the result is still the same:

Hey, may be you have some github "project done" repo for PlatformIO? It would be nice:)
Hello Denys, do you put UI files into libraries? Or did you put the wrong UI file?
Hello, yeah I did. As in .pdf instruction :)
I've added UI files as it was in .pdf instruction, but still have the same issue.
Hello dear Elecrow support team, I'm still waiting for your support. Today I've done everything as in instruction, but I've got the same result. Could you please send me any already done repository with some simple demo project?
Thank you in advance!
Hi Denys, our tech team is already working on the problem. I'll get back to you as soon as I have the results. I will ask the R&D staff if there is a simple demo. Thank you for your patience.
Hello Denys, this may take some time. Because the engineers are working on other projects. They spend their free time studying your problems. Thank you for your understanding.
Hello
Okay, thank your for respond. I'll be waiting
