CrowPanel 7" inch - can we use esp-idf without arduino?

anujdeshpande

ESP-IDF has support for RGB panel - see example. Is it possible to use this example with the 7 inch display??
The dimensions in the example are also 800x480. I would like to avoid using Arduino.

Hello @anujdeshpande ,
Thanks for your sharing. Please refer to this example: https://www.elecrow.com/download/product/ESP32_Display/7.0inch/ESP-IDF_7.0.zip

@Elecrow That uses arduino-esp32.

The RGB panel library provided by Espressif might not support the driver use in the CrowPanel 7.0'' display(EK9716BD3 & EK73002ACGB).

I was able to get it working with the rgb_example in esp-idf @Elecrow . I think you can update your wiki as well so that other folks can use ESP IDF directly without resorting to Arduino-IDF
You can find it here - https://github.com/espressif/esp-idf/tree/master/examples/peripherals/lcd/rgb_panel

I needed to make a few changes

• change the pin mapping
• update the hsync/vsync/pulse/porch values
• I also changed the LVGL version to a version I needed (8.4.0) but it should work without this particular change IMO.

Thank you for your feedback. I have forwarded your message to the engineer and we will update the wiki after we update the demo code. Thanks again for your help!
