phalski-ledshim

A basic application framework for the Pimoroni LED SHIM.

Features:

• Easy animation development
• Flexible pixel segmenting
• Running multiple animations simultaneously
• Basic charting supported out of the box

Examples

Basic usage:

from phalski_ledshim.threading import Application
from phalski_ledshim.animation import Rainbow

# create application with default settings: ~16fps refresh rate + full brightness
app = Application()

# init a rainbow animation for the first 8 using 16 colors at normal speed
r1 = Rainbow(app.pixels[0:8])
# init a second reverse rainbow animation on the other pixels with more colors and a faster speed
r2 = Rainbow(list(reversed(app.pixels[8:27])), 32, 4)

# execute both animations with a refresh_rate of 0.1 (~10 times/s)
app.exec((r1, 0.01), (r2, 0.01))

Using charts (requires psutil):

import psutil

from phalski_ledshim import Color
from phalski_ledshim.threading import Application
from phalski_ledshim.charting import ChartSource, BarChart, ValueSpecification

# create application with default settings: ~16fps refresh rate + full brightness
app = Application()

fg = Color(255, 0, 0, 1.0)  # full red
bg = fg.dim(-0.75)  # 75% reduced foreground color

# init a bar chart animation that accepts values between 0 and 100 and uses the above colors
chart = BarChart(len(app.pixels), ValueSpecification(0, 100, False, True), fg, bg)

# create a chart source that visualises the current cpu load
source = ChartSource(app.pixels, chart, lambda: psutil.cpu_percent())

# execute the chart source with a refresh_rate of 100ms (~10 times/s)
app.exec((source, 0.1))
