Using scratch to access the GPIO ports on the raspberry Pi

mikado79

Hi,
I have a raspberry Pi and can access the GPIO Ports with python but how do I do it from scratch, please?
Thanks to anyone who can help or at least point me to some reading matter on the subject.
Also when will scratch 2 be available to download?

Scratch 2.0 will be available for download nearing the end of summer (So right about now, i would say.

Which Scratch version are you planning on using? Im assuming 1.4, it comes with the Raspberry Pi.
If you are planning on using Scratch 2.0, I would not recommend it. It runs slow on mine. Use Scratch 1.4, which has a protocol called Remote Sensors Protocol. Check out this http://mv.ezproxy.com.ezproxyberklee.flo.org/wiki/Remote_Sensor_Connections
Remote Sensors Protocol is basically where you take your Python program, and hook it up to communicate with Scratch. There is a specific example on the wiki for Python, but you can use other languages as well. I managed to do it in C#.

I don't know. Maybe you need a stupid computer to do that.

new interface for scratch v1.4 can control,rs-pi v2 P5 ( got extra GPIO 28,29,30,31) use GPIO number , not use p1 pin number.

can support i2c /32/64/128 GPIO
i2c temp sensor/RTC/ i2c servo motor
GPIO stepper Motor, relay…
h-bridge Motor control up to 6 DC motor

I think that you need to set it to Chinese… but I don't really know more about that.

Simon's got some new updates (only for scratch 1), it works really well with the Pi.
