Very basic question I’m sure but how do I use the “call function” action and where in my own code do I place this?
I’m currently working on a ESP32 project using Arduino IDE.
As an example, I’ve created a label called “myMultiplyFunction” and the result of this I would like to display as an integer on the screen.
On the ui_events.c file I see the action and a prompt:
void myMultiplyFunction(lv_event_t * e)
// Your code here
As a test to understand the process, is this where I would include some sort of Serial.print statement or other function code to display.
Just looking for some guidance/resources on how to print/show/update data to the screen.
Thank you for any help.
