[Dashboard] how to watch a global variable?
I use watch
action as shown below(changed from SerialPort
exmaple), but it didnt work.
-
add a user action: watchSerial. it watchs serial connection status.
-
add
watchSerial
to page
Test:
when i click Connect
button, no output is seen in the logs area.
can watch
action be used in a user action?
