Using ESP-IDF code in Arduino code?

[vritzka]

Hello,

I’m working on a project with a large LCD display on the EDP32-S3.

I have the LCD working with the provided sample code https://github.com/espressif/esp-idf/tr ... /rgb_panel.

However, I’m struggling to write the rest of my app with the ESP-S3. My skills are not good enough.

So I switched to Arduino core. But now I cannot get the RGB LCD panel working.

Is there a way to use the ESP LCD code in Arduino?

Thanks

You can use ESP-IDF in Arduino

I suspect your issue is not in using esp-idf in Arduino, but rather using C-style code in C++.
When assigning struct's in C++, you cannot leave missing identifiers, and it will not automatically cast elements into the correct type. There are a few fixes:
- If you are including a header that will have C code in it, use an extern "C" (https://github.com/espressif/arduino-es ... pp#L31-L33)
- If you have missing identifiers, look at the struct definition and add those into the assignment. If you have very few elements to assign in a large struct, do away with the C-style dot assignment, and assign the elements explicitly with the top-level variable (mystruct.myelement = val;)
- If you have invalid conversions, force cast that identifier into the appropriate variable type or use the correct variable type in your assignment

Yes you can. Your Arduino code is simply... calling low-level ESP-IDF functions.
So you can skip these "macros" and call these ESP-IDF functions directly.

Thank you, this was very helpful.
