10. @ben_nuttall #AllThingsOpen Mu
11. @ben_nuttall #AllThingsOpen GPIO Pins – General Purpose Input/Output
12. @ben_nuttall #AllThingsOpen 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
20. @ben_nuttall #AllThingsOpen Picamera • 8 megapixels • Visible light & infra-red versions available • 1080p30, 720p60 and VGA90 video • Command line interface and Python library
21. @ben_nuttall #AllThingsOpen Sense HAT • 8x8 RGB LED matrix • Mini joystick • Temperature sensor • Humidity sensor • Pressure sensor • Accelerometer • Gyroscope • Magnetometer
22. @ben_nuttall #AllThingsOpen Astro Pi • 2x Raspberry Pis on the International Space Station • Space grade aluminium case • Sense HAT • RTC • Camera (Vis / IR) • Astro Pi competitions • Mission Space Lab • Mission Zero
23. @ben_nuttall #AllThingsOpen Astro Pi • 2x Raspberry Pis on the International Space Station • Space grade aluminium case • Sense HAT • RTC • Camera (Vis / IR) • Astro Pi competitions • Mission Space Lab • Mission Zero
24. @ben_nuttall #AllThingsOpen 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
