It's possible to dynamically change the screen title text and action button labels.
|
||
|
|
Setting an empty label to a button makes it look disabled. The buttons send ASCII 1-5 when clicked.
|
||
|
|
Those changes are not retained after restart.

This ASCII code is not a command, but is sent by ESPTerm when it becomes ready to receive commands.

When this code is received on the UART, it means ESPTerm has restarted and is ready. Use this to detect
|

|
|
spontaneous restarts which require a full screen repaint.
