Raspberry Pi GPIO Demo
Example of interacting with GPIO pins on a Raspberry Pi
Controlling_GPIO.drunau
Description:
This Skill demonstrates how to interact with the Raspberry Pi GPIO pins using a Mycroft Skill. This Skill shows both reading data from a GPIO port (detecting a button press) and writing data to the port (illuminating an LED).
Preparation
You will need to first install the GPIO libraries for Picroft, and add some additional permissions.
Generation
The documentation is done using Sphinx, which picks up comments from the code. The following will generate the html docs.
make docs
You can then find the generated html in docs/build/html/index.html. Open that file in your browser and you should be able to navigate to the docs.
Installing from the makefile
makefileChange the Makefile IP address for the RPi installation to the IP address of your RPi.
That is, edit the file makefile using your favorite editor like nano or vi.
The line you will need to change is scp -r * pi@192.168.205.115:/opt/mycroft/skills/skill-gpio.
Change this to have the IP address of your RPi.
Create the folder
/opt/mycroft/skills/skill-gpioon the RPi for the installer.
You can do this by using the command mkdir /opt/mycroft/skills/skill-gpio
Build the code using the
makefile.make install.pi
Testing the makefile
makefilemake test.pi
This will run a test to be sure you have access to the GPIO and will report any errors that are identified.
Notes
If the LED blinking is too fast, it will be difficult to get a command to execute because there will be a voice response when the the LED turns off and on. Turn the blinking to a lower frequency to be able to execute commands.
Circuit
Please use the below image as a guide to the circuit layout:

Examples:
Turn LED on. Turn LED off. Blink LED. LED status.
