I recently tried following the instructions listed here: http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/RaspberryPi_GPIO/RaspberryPi_GPIO.html#section1
I was able to do the extremely simple stuff like output hello to my PI. However, I could not get changes written to the GPIO pins to take effect, using either the method described in the default code, or creating a DeviceConfig.
I used the WiringPi utility to test if maybe my wiring was bad, but I was able to blink the LED from WiringPi. Something interesting, is that using
gpio readall shown the changes that the imlet wrote to the pin (setting
1 to turn on an LED), but there was not actual change on the LED. This worked the same for trying to turn and LED on and off.
I have the permissions configured correctly (I think...).Is there anyone who has got this working, that could perhaps send me their project?
