You can check out my Python Wiki post on it, under the “Mac Notes” section. On a side note I should point out I went to great lengths to get this working on my Mac, without a lot of success. Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for Raspberry Pi.

To see the list, you can visit this page. Only a few core libraries are currently supported. # wait for 30 milliseconds to see the dimming effect # reverse the direction of the fading at the ends of the fade: # change the brightness for next time through the loop: Here is a port of the basic Arduino Blink sketch: from nanpy import Arduino as AĪ.digitalWrite(led, A.HIGH) # turn the LED on (HIGH is the voltage level)Ī.digitalWrite(led, A.LOW) # turn the LED off by making the voltage LOWĪnd a port of the basic Fade sketch: from nanpy import Arduino as A Hook up your Arduino to one of the Pi’s USB ports, and create/upload the new firmware (using an Arduino Uno as an example): $ cd ~/nanpy/firmwareįrom there, programming my Pi via the Adafruit WebIDE (and with my Arduino hooked up to a breadboard with the required led’s and resistors), I recreated a few basic Arduino sketches to see how it worked. Now install the required Python libs: $ sudo pip install nanpy Next, install the nanpy source: This is needed to later build the new Arduino firmware: $ cd ~ You need to specify the serial port you art using when you create your serial object. It allows you to easily control your Arduino from Python, and it installs on the Pi in a snap:įirst, install Arduino: $ sudo apt-get install arduino To read serial data, you can use the Python serial library. To do so, you will either be prompted, or you can type. After this, make sure to restart the Raspberry Pi.

The serial login shell is disabled The serial interface is enabled. I recently ran across the nanpy library for Python when looking at different internet radio projects using the Raspberry Pi. Once the Raspberry Pi has made the changes, you should see the following text appear on your screen.
