class
adafruit_is31fl3731.
CharlieWing
(i2c, address=116)[source]¶ Supports the Charlieplexed feather wing
-
class
adafruit_is31fl3731.
Matrix
(i2c, address=116)[source]¶ The Matrix class support the main function for driving the 16x9 matrix Display :param ~adafruit_bus_device.i2c_device i2c_device: the connected i2c bus i2c_device :param address: the device address; defaults to 0x74
-
audio_play
(sample_rate, audio_gain=0, agc_enable=False, agc_fast=False)[source]¶ Controls the audio play feature
-
autoplay
(delay=0, loops=0, frames=0)[source]¶ Start autoplay :param delay: in ms :param loops: number of loops - 0->7 :param frames: number of frames: 0->7
-
fade
(fade_in=None, fade_out=None, pause=0)[source]¶ Start and stop the fade feature. If both fade_in and fade_out are None (the default), the breath feature is used for fading. if fade_in is None, then fade_in = fade_out. If fade_out is None, then fade_out = fade_in
param fade_in: positive number; 0->100 param fade-out: positive number; 0->100 param pause: breath register 2 pause value
-
fill
(color=None, blink=None, frame=None)[source]¶ Fill the display with a brightness level :param color: brightness 0->255 :param blink: True if blinking is required :param frame: which frame to fill 0->7
-
frame
(frame=None, show=True)[source]¶ Set the current frame :param frame: frame number; 0-7 or None. If None function returns current frame :param show: True to show the frame; False to don’t force a show
