many problem with flashing, libraries and so on
hello, after nearly 10 days trying to program the display 3.5" RGB with ESP32 on board, I wonder if it is just me or something is wrong. I watched the video tutorial, read the FAQ, read all the wiki I could, still nothing with the LVGL. (I was using platformIO, now I was back to the simple Arduino IDE bot nothing works.
demo 1-2-3 work fine, meaning I can at least program the display. as soon as I try ANY of the projets that use the LVGL library, I got errors, missing declarations, not compiling, rebooting... all sort of stuff. I tried getting the binary for my display, from here (https://drive.google.com/drive/folders/1Xz1tuBNntUsRqush3lCJdswCROLSS95Z) and usint the EspressiF Flash Download tool (v3.9.5) to just upload the factory program, without success.
I need help. can you please share a clear tutorial or demo file that are proven to work? can you correct the un-precise tutorial on how to flash the board? or, at least, update to the last libraries? any one that succeded in getting the SquareLine studio to work with 3.5 tft LVGL + Arduino + TFT_RGB display type? it is frustrating, and in 10 days the demo license will be over. I won't buy it at this condition.
thank you

You find attached my files to setup the Hardware and start LVGL. Please ignore the lines related to PCA9548. That's an I2C multiplexer, which I ue for some projects. Those files are for a portrait mode screenand compilation with Arduino IDE or VSCode. You need to install the libraries which are in the include statements first.
Hope it helps ;-) It took me also a while to understad the setup
Hello @lucacrotti ,
Please find the bin file at: https://drive.google.com/drive/folders/1MRTFqZ4Xe2yA8_Y0u8WEs_qqlJIt0HKQ?usp=sharing
You can refer to this post:https://forum.elecrow.com/discussion/510/how-to-install-the-factory-demo-firmware-with-flash-download-tool/p1?new=1to flash the demo firmware.
For the PlatformIO demo please refer to: https://www.elecrow.com/wiki/index.php?title=ESP_Terminal_3.5-inch_Display_PlatformIO_Tutorial
For the Arduino demo please refer to:https://www.elecrow.com/wiki/index.php?title=ESP_Terminal_RGB_3.5-inch_Display_Arduino_Tutorial
Unfortunately the 3,5 inch platformio does not work at all. Impossible to compile. Which platformio ini do i need for the 3,5 inch display with WROVER and not wroom controller ? Compiling stops on a not found wire.h library. Which wire.h library do i need ? Also needed is the GFX library. But even after uploading this library the example odes not compile...
I manage to compile the first lesson (uart.ino), flash it and it works. Lesson2 gives errors on compile: apparently wire.h is not found and the touch function is not available since the touch pin has not been declared. (But this last problem also exists in the Arduino IDE and is not a blocking thing, only a warning)
And last but not least, another error: ld.exe: cannot find-lspi
Hello @kweetje ,
Are you using our demo code?
Did you place our libraries in your libraries folder?
Please refer to this website and ensure the libraries are in the correct folder.

Could you take a screenshot of all your libraries and upload it here？
You can download all our libraries at this link:
