Description
I have recently purchased a ESP32-2424S012 (ESP32-C3 Entwicklungsboard 1,28 Zoll rundes LCD-Display mit Touchscreen und WLAN-Bluetooth-Modul - AliExpress 44). No documentation nor reference were provided with the hardware 
I made a nice UI on SquareLine studio to be run on my ESP32-C3. I have used the âcreate project templateâ option, then âexport UI filesâ.
I have received indeed the project with apparently everything i need. Then, i opened Arduino IDE with the main âui.inoâ file. I set on the IDE the right Sketchbook location. I managed to compile and upload with no error on my device.
The thing is⌠when i received the ESP32-C3, it had its own demo software and it was running fine. Since i uploaded my project, nothing is displayed anymore.
I also updated the User_Setup_Select.h file on libraries/TFT_eSPI to enable #include <User_Setups/Setup46_GC9A01_ESP32.h>. on User_Setup.h, i enabled #define GC9A01_DRIVER.
I am out of ideas about how to solve this issue.
Thanks for your support!
What MCU/Processor/Board and compiler are you using?
ESP32-2424S012
What do you want to achieve?
Show my UI on screen
What have you tried so far?
I tried different configuration found on topic in this forum, no progress so far
