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. Le 2016-05-27 20:11, sergio ruiz a écrit :

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!

There doesn't seem to be many Pharoisms in WiringPi; for a much snappier experience, you might want to check out Squeak instead. Raspbian ships with both Spur and Non-Spur VM's included (courtesy of Scratch) which include optimized BitBlt primitives (may be absent from the old Pharo VM) + it uses bitmap fonts and has less configurable, but faster tools. Since WiringPi uses FFI though, you'd have to find and load that manually before the actual WiringPi package, no metacello config for squeak afaict. Cheers, Henry

My bad, the leds were not on the right pins. Now all my leds are off and my wiring is ok. It still doesn't work, but i'm not sure whether my setup is wrong or if it just doesn't work anymore on Pharo5.

I will attempt to use the library outside Pharo, reconfigure a Pharo image & vm and then try it again.

In the meantime if anyone does success at this, please let me know i am very interested by using the GPIO pins from Pharo.

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.

I have a project that his waiting on this.

Thanks!
