Script Running Slow - Raspberry Pi Forums

hello all!

started messing raspberry pi 3 week ago, i'm total noob.

i've researched gpio control , threaded callbacks. i've written runs slow i'm wanting do, there
i'm doing wrong?

i'm going control of lighting on car 3 pis connected copper make local network, , @ moment
i'm working on tail lights.

works desired reaction time slow.

here's code.

video can see delayed reaction time input interrupt.

appreciated!

wow. crazy slow threading.

see in code when calls threaded routine set global variables prints screen. in video don't show screen. when press button there same delay before prints screen or print straight away take time before main routine call actual function blinks light?

me seems long winded way of doing it. u have threaded call set global variable test global variable in main loop call routine changes lights. think done in threaded call routine main program loop waits keyboard input exit clean up.
