Hi Steven, I'm also interested. I'll received a Pi 3 soon and I'll want to use the GPIO as well, as well as looking at performances issues, especially at the IDE level. Have you tried to use: - command line manipulation of the GPIO via OSProcess ? Create a GPIO file access: echo 11 > /sys/class/gpio/export Configure the Pin Direction (In/Out): echo out > /sys/class/gpio/gpio11/direction Write a value to turn on the LED using the GPIO11: echo 1 > /sys/class/gpio/gpio11/value *Now your led should be ON!!!* Write a value to clear the LED using the GPIO11 echo 0 > /sys/class/gpio/gpio11/value *Now your led should be OFF!!!* Delete the created GPIO (11) echo 11 > /sys/class/gpio/unexport (you can run those commands from Pharo) Those commands reach ~ 4 kHz on toggling on or off a gpio pin.

Please keep us posted on this.

Thanks!

Hi,
i have tried to make it work but so far i can't get it right. Have you been able to work with it ?
I used pharo 5 latest non spur image with the non spur vm. It works on a raspberry 3 but it is very slow. I tried the led examples, the leds do not seem to be affected (some are on, some off, with a variable intensity).
Is there any specific settings needed for this to work ?
Thanks,
Steven.

does anyone know if if pharo 5 runs on raspberry pi yet?
if so, i can poke around and see if i can get WiringPi to install on pharo 5.
thanks!

Pharo code ( probably on Pharo 3 or 4). http://smalltalkhub.com/#!/~jeanbaptistearnaud/WiringPi
great! i'll take a look at those!
thanks!
