GPIO components

13. @ben_nuttall#AllThingsOpen
Add-on boards / HATs

14. @ben_nuttall#AllThingsOpen
GPIO Zero – a friendly API for GPIO devices
from gpiozero import LED
led = LED(2)
led.blink()

15. @ben_nuttall#AllThingsOpen
GPIO Zero – a friendly API for GPIO devices
●
Zero-boilerplate Pythonic library
●
Intended for use in education
●
Simple, guessable API with
commonly used names and
sensible default values
●
Simple introduction, smooth
learning curve
●
Multi-paradigm
●
Extendable

16. @ben_nuttall#AllThingsOpen
Multi-paradigm: procedural (polling)
from gpiozero import LED, Button
led = LED(17)
button = Button(4)
while True:
if button.is_pressed:
led.on()
else:
led.off()

17. @ben_nuttall#AllThingsOpen
Multi-paradigm: procedural (blocking)
from gpiozero import LED, Button
led = LED(17)
button = Button(4)
while True:
button.wait_for_press()
led.on()
button.wait_for_release()
led.off()

18. @ben_nuttall#AllThingsOpen
Multi-paradigm: event-driven (callbacks)
from gpiozero import LED, Button
led = LED(17)
button = Button(4)
button.when_pressed = led.on
button.when_released = led.off

19. @ben_nuttall#AllThingsOpen
Multi-paradigm: declarative
from gpiozero import LED, Button
led = LED(17)
button = Button(4)
led.source = button.values

piwheels
●
Python package repository providing Arm platform wheels for
Raspberry Pi
●
Builds automated from PyPI releases, plus manual builds e.g.
opencv & tensorflow
●
Raspbian is pre-configured to use piwheels.org as an additional
index to PyPI
●
Massively reduces pip install time for Raspberry Pi users (saved 30
years of build time in 11 months)
●
Natively compiled on Raspberry Pi 3 hardware (Mythic Beasts Pi
cloud)
●
Repo hosted on single Raspberry Pi serving over 500k packages
per month
