Apologies for the previous email; I think I sent it in HTML format.
Gmail changed their user interface again...
This is how I'm checking for a button press:
modes = (weather, alarmclock, moodlight)
currmode = 0
mode = 10 ## mode button is on pin #10
def checkMode():
'''Returns the current mode and whether a mode change was detected.'''
global currmode
modechange = False
GPIO.setup(mode, GPIO.IN)
if GPIO.input(mode) == False:
print "Mode button pressed."
if currmode < len(modes) - 1:
currmode += 1
else:
currmode = 0
modechange = True
#print modes[currmode]
return (modes[currmode], modechange)
It's pretty simple, really. If GPIO.input(mode) returns False, then
the button is pressed. My function above returns the current mode
from my modes tuple, and whether a change was detected.
