1 year ago Dilemma: in order for patterns to cycle while other stuff is happening, this has to be non-blocking and essentially generate led state based on timestamps. This goes against the though of it being an easy place for beginners to tinker with code.
@kcreyts you put your name on this one, but some of my brainstorming might be helpful - don't hesitate to ignore it and do what works.
there are two pins, NEOPIXEL and NEO_PWR. NEO_PWR is connected to a mosfet that grounds the neopixels when high, to save power when they're off.
variables:
- duration: this is how long before the animation cycles. timestamp%duration should tell the animation what frame of the pattern to do
- color: for single-color patterns, this should hold the color
- pattern: string to choose one of several patterns - flash, rainbow, chase, breathe, off, etc
init:
- turn off power
- initialize neopixel string (10 RGB LEDs)
- set pattern to off
update(self, newpattern=None)
- if newpattern is none, then just repeate the existing pattern, otherwise update self.pattern
- if pattern is off, turn off power and return
- ifelse tree of each pattern. Simple patterns can be inline, complicated ones should be separate functions.
power_on() and power_off(): set/clear the NEO_PWR I/O

likely plenty of open source examples to choose from. Should probably include at least:
these patterns should be contained in a separate .py file with comments to tell end users how to modify them The current pattern should be selectable from the settings menu.
