work on #9: cbus_read() bugfix suggested by @lsgunth #10

Applied bugfix for cbus_read()

lsgunth commented 5 years ago

I've made a small change to this because I'm worried python 2 won't work with it. Can you please test the "JBSchueler-feature/9_bugfix_cbus_read" branch in this repo?

Once you confirm it still works I'll merge it into master.

Thanks,

Logan

I verified f5841f67dcef45c9938a71d72ef65a4534e9e8ff code has not been broken.

...
#If you want to use the CBUS pins, you enable them with cbus_setup
# 'mask' is a bitmask which specifies which pins to enable
# 'init' is a bitmask for the initial value for each pin
sp.cbus_setup(mask=3, init=3)

#Change the current value of all setup pins
sp.cbus_write(0)
print("CBUS = %s" % sp.cbus_read() )
sp.cbus_write(1)
print("CBUS = %s" % sp.cbus_read() )
sp.cbus_write(2)
print( "CBUS = %s" % sp.cbus_read() )
sp.cbus_write(3)
print( "CBUS = %s" % sp.cbus_read() )
