Im a newbee at python, and im trying to figure out how to use variables and
setups across modules.
Am I right when i think its smart to keep seperate functions of a program in
seperate modules?
I have a main program module called main.py and in that main.py i have this:
# Sets GPIO's to HIGH = Relays OFF
try:
import RPi.GPIO as GPIO
except RuntimeError:
Print("Error importing RPi.GPIO!!")
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
# GPIO16 is relay1
GPIO.setup(16, GPIO.OUT, initial=GPIO.HIGH)
# GPIO11 is relay2
GPIO.setup(11, GPIO.OUT, initial=GPIO.HIGH)
I then import a module (in that module1 i have a function called Relay) and try
to use the function with module1.Relay(1,1)
But the function in module1 needs the GPIO from the main.py to Work. How do I
go about with this? I really dont want the GPIO setting part in the module1, I
dont want it to be run everytime I run the module1.Relay(1,1) call..
What is best practice for working across modules. (im making a controller for
my house' heat system, so it would be nice, if I can do this the right way, the
first time.)
Im and experienced vbs and php coder, but a real newbe when it comes to python
;)
I Really hope you Guys will lead me in the right direction..
Kind regards Juel
