ArduinoIDE Compilation Error

[extremerotary]

Good evening,
Similar to some other issues reported and feedback regarding PlatformIO - I would absolutely prefer to use this IDE over Arduino, but for now, I'm trying to get your example demos to compile and display. I am not new to LVGL, but am new to this specific display and I have trouble getting it to compile and initialize LVGL. Once that occurs, I will be completely fine as I can create the LVGL objects/screens/etc and handle the gesture events, etc. I've always struggled to get the initial source code set up for new devices/displays.

1. I created a new sketch in ArduinoIDE and saved it. I used your example code from the readme.
2. I then went to the library manager and added the waveshare_ST7262_LVGL inch which under 'more info' links back here - https://github.com/iamfaraz/Waveshare_ST7262_LVGL . This seemed to install all necessary dependencies as you have that in your library.json file.
3. I navigated to my documents/arduino/libraries and copied the LVGL directories of demo and example from their current structure to the ./src directory per your instructions.
4. Restarted ArduinoIDE to be safe.
5. From your example code on the readme, I then uncommented out the "#include <examples/lv_examples.h>" and attempted to compile.

The code is massive in comparison to other devices I have dealt with. Even with commenting out the example and demo includes, it's 60% of 8Mb. Any idea how to reduce that? I would love to be able to simply load the necessary drivers for the display and touch chips and then initialize the LVGL library.

I also put in a pull request to correct the ESP_IO_EXPANDER_I2C_CH422G_ADDRESS - please accept
