display.prompt() command.
Example
reset()
trigger.model.load("SimpleLoop", 10, 0, defbuffer1)
display.prompt(display.BUTTONS_YESNO, "Would you like to make 10 DC voltage
readings now?")
promptID, result = display.waitevent()
if result == display.BUTTON_YES then
trigger.model.initiate()
end
display.prompt(display.BUTTONS_YESNO, "Would you like to switch to the Graph
screen?")
promptID, result = display.waitevent()
if result == display.BUTTON_YES then
display.changescreen(display.SCREEN_GRAPH)
end
Create a simple loop that will make 10 measurements and save them in default buffer 1.
Display the prompt "Would you like to make 10 DC voltage readings now?"
If the user presses Yes, the measurements are made.
If the user presses No, the measurements are not made and the message is removed.
Display the prompt "Would you like to switch to the Graph screen?"
