Can anyone tell me if this scheduler has been used for tasks more complex than blinking LEDs or outputting messages to a serial?
For example, working with displays, or even better, working with the lvgl graphics library?

Does the library have the ability to work with a dual-processor esp32s3 microcontroller?
Is there some kind of analog of a mutex like in freeRTOS?

I would be glad to have a constructive discussion with engineers
