hi to all:
I've serially communicated a text value into a text component on say page 0. Then I switch to page 1, do some stuff, then when I switch back to page 0 the text components are blank.
Clues on how to refresh these components upon page entry would be appreciated (I've tried component refresh, no avail).
I thought of that for a solution but was hoping for something more elegant, ie internal to the nextion system. Thanks for the tip anyway . . .
set the txt component as "vscope:global".
refer to this example:Advanced Application 2: Use Global and Variable to Transmit Values Among Pages
ok, thanks. so that keeps the text stored on that page. This is good to know as I can use it.
But I was looking for the text to be stored in a variable that each page displays, i.e., each page displays the same identical text.
It can be done within nextion (no need for Arduino or another MCU)
you have to:
- Set the components as "Global" (important)
- in the other page you write this syntax: pagename.componentvalue="..."
example: you need to set text value of text t1 in page A to "button pressed" when button b1 in page B is pressed
so you write in the events of button 1 of page B: A.t1.txt="button pressed"
ok, I understand but this is not what I need.
I send a "text value" via serial to page A t0.
t0 now displays "text value"
Change to page B and t0 is blank.
Change back to page A and t0 displays "text value".
I just want "text value" in t0 on every page.
