ESP32 7inch display V3.0 touch isn't work
If your ESP32 V3.0 touch screen doesn't work,or Lesson 4 touch example code doesn't work,
you can try to use the attached file upload code to make the touch work.
Note that the ESP32 version is 2.0.x, not 3.0+.
The CrowPanel_ESP32_LVGL_Demo attachment contains the main program and gfx_conf.h for Lesson 5.
Please replace the main program and the gfx_conf file, and it should work properly.
If you want to test the code for the later lessons, you can add new content on the basis of this LVGL_DEMO , replace gfx_conf.h in the same way.
Our engineers will update all lesson codes as soon as possible.

If the touch functionality of your ESP32 7-inch display V3.0 isn't working, 3patti world 2023 here are some troubleshooting steps you can try:
Ensure the touchscreen cable (usually FPC ribbon) is properly seated in the connector.
Double-check the SPI or I2C wiring if you're using a resistive or capacitive touch screen.
Some touch screens require 3.3V or 5V power to function.
Make sure the display is getting the correct voltage and current.
Depending on the display model, you might need drivers like:
FT6236 (Capacitive Touch)
XPT2046 (Resistive Touch)
Ensure the correct driver is included in your ESP32 firmware.
Thanks for the update! I'll try using the attached files and replacing the main program and gfx_conf.h as suggested. Looking forward to the updated lesson codes.
This was working for a while but is now broken again - I have confirmed the board version and used all the elecrow provided libraries.
edit - I see a whole bunch of the github was updated a week ago, I'll try the newer files and report back
