Post by: bellad on June 30, 2014, 04:47:54 AM

hello,
hi try wiringpi.tcz on 5.3  , but when i do

Code: [Select]

import wiringpi
ImportError: No module named wiringpi

You're missing either a perl or python module?

wiringpi.tcz provides the command line tool and dev libs to manipulate GPIO. No Python module provided, it is the original WiringPi.

What you are looking for is the WiringPi2-Python fork, which is not yet available in the repo.

The old WiringPI does not work with the newer rpi firmware.   version 2 should include the patches.

For Python I use.  RPIO.   http://pythonhosted.org/RPIO/index.html

thank paul
RPIO is not repo ?

my project : by python , use bmc gpio : lcd ( rs -> 10 , e -> 7 , d4 -> 9 , d5- > 25 , d6 -> 11 , d7 -> 8 )
 relay ( x5 ) : re1 -> 4 , re2 -> 17 , re3 -> 18 , re4 -> 27 , re5 -> 22
i use spi and ce pin's for lcd

with wich module the best for python ( RPI.gpio - wiringpi2 - RPIO or other )  ??

thank you

RPIO is not in the repo, but it is easy to add yourself.  But I took a look at the GPIO library on the repo.  It is now fairly full featured and supported/updated better.  I would use that.

At the time that I started using my GPIO, RPIO had the interrupt programming, where the basic python GPIO library did not.

python-RPi.GPIO.tcz updated to latest 5.5 release.

thank paul and markus

i try rpi.gpio , is what manages rpi.gpio bmc gpio : lcd ( rs -> 10 , e -> 7 , d4 -> 9 , d5- > 25 , d6 -> 11 , d7 -> 8 )
beacause no display with my code :

oups !!
i do error with plug lcd module
it is good , except that no display what I want
i search why
