When working, exactly what does the touchscreen do for us and the app?

Question

Most everything works on the first try, nice, but what does the touchscreen do for us.  Mine is not working, most likely for the warning about TOUCH_CS not defined.  OK, can't find it.

Where do I enable or how do I find/view the log_i data?

Bottom line is I'd like the touchscreen to be enabled.

Thanks,
Tony

Hi Tony

You are right, the current version of the ESP32 Weather Station Touch is not using the capacitive touch screen. There commented code in the project which shows how to use the touch screen driver:
https://github.com/ThingPulse/esp32-weather-station-touch/blob/master/src/main.cpp#L104

If you want to build something more complex we also have an example project which shows how to build sophisticated user interfaces with touch screen:

I hope this will answer some of your questions!
