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.
