Delay with Nokia display and blynk

[ondraczsk]

Hi, I have small problem with my code. I have nokia display, some sensors and buttons.
In my code is Nokia 5110 display menu - you can control the menu with buttons - but when I want to control it like pressing down and up buttons it has small delays and it is unconfortable and laggy. Is there some solution to avoid it?

Aside from combinations of these functions being called at the same time every 3, 6, 9 & 10 seconds (and possibly more)

Search this forum for way to space out your timers.

@ondraczsk

timer.setInterval(100L, initialize);

Everything running in your initialize() function, 10 times a second, is what is causing your lag.

Look into (AKA Google) using interrupts instead of polling for your button checks.
