1. Is this possible using just one encoder? While in the function, I want to process the encoder. When I exit this callback function, I want the menu to re-engage and take over the encoder input.
2. The plan would be to use the encoder switch to exit from this subtask to get back to the menu system. Is that button event something I can capture in the processing function?
3. Aside from exiting the callback function, should I be executing any tcMenu function prior to exit?
4. Can I use the same "lcd" variable for displaying the results as used by the menu system?
1. It looks like I could schedule a task to read from the serial line every xxx ms.
2. Seems like it would not be efficient to take over the display on every character that I receive. Is that the best practice or would a different approach be advisable?
