class adafruit_crickit.Crickit(seesaw: adafruit_seesaw.seesaw.Seesaw)

Represents a Crickit board. Provides a number of devices available via properties, such as servo_1. Devices are created on demand the first time they are referenced.

It’s fine to refer a device multiple times via its property, but it’s faster and results in more compact code to assign a device to a variable.

import time
from adafruit_crickit import crickit

# This is fine:
crickit.servo_1.angle = 0
time.sleep(1)
crickit.servo_1.angle = 90
time.sleep(1)

# This is slightly faster and more compact:
servo_1 = crickit.servo_1
servo_1.angle = 0
time.sleep(1)
servo_1.angle = 90
time.sleep(1)

init_neopixel(n: int, *, bpp: int = 3, brightness: float = 1.0, auto_write: bool = True, pixel_order: str | Tuple = None) → None

Set up a seesaw.NeoPixel object

Note

On the CPX Crickit board, the NeoPixel terminal is by default controlled by CPX pin A1, and is not controlled by seesaw. So this object will not be usable. Instead, use the regular NeoPixel library and specify board.A1 as the pin.

You can change the jumper connection on the bottom of the CPX Crickit board to move control of the NeoPixel terminal to seesaw pin #20 (terminal.NEOPIXEL). In addition, the Crickit FeatherWing always uses seesaw pin #20. In either of those cases, this object will work.

from adafruit_crickit.crickit import crickit

crickit.init_neopixel(24)
crickit.neopixel.fill((100, 0, 0))
property neopixel: adafruit_seesaw.neopixel.NeoPixel

`adafruit_seesaw.neopixel object on NeoPixel terminal. Raises ValueError if init_neopixel has not been called.

property onboard_pixel: adafruit_seesaw.neopixel.NeoPixel

`adafruit_seesaw.neopixel object on the Seesaw on-board NeoPixel. Initialize on-board NeoPixel and clear upon first use.

reset() → None

Reset the whole Crickit board.

property seesaw: adafruit_seesaw.seesaw.Seesaw
