hi all,
I´m new to ESP6288, but I got a simple WIFI Server based Garagedoor opener working.
It just puts some GPIOs HIGH or LOW as needed.
In order to add more functionality, I have tested the interrupt mode of the GPIOs, to detect i.e. when the door is fully closed or opened and stop the motor. That works also well.
But I´m having problems combining this two tasks.
I tried also timer alarms to check if the end-switches are activated, but until now I havent succeeded.
Can you give me a hint how to perform this tastks "parallely"? ( I know, it is not really parallel, but it should be possible to stop the motor 0.5 seconds after reaching the end position...)
this is my code:
the wifi connection is established in the init.lua, then it passes to "garage.lua":
