#Rotary encoder NeoPixel code
queen smelt
Yes.
Actually, I'll send the file. Not sure it'll fit.
I adapted this from some code JP wrote that used Debouncer. Which as convenient as it is, I'm not going to do because it doesn't match the Arduino sketch.
Plus, it only flashes the LED(s) when you press the buttons because it only sees one press.
hardy hornet
instead of looping on the buttons, just check them individually
queen smelt
Unrelated, when I press the center button, I hear a quiet pulsing tone from somewhere.

ard skethc for ref:
if (! digitalRead(BUTTON_UP)) {
pixels.setPixelColor(0, pixels.Color(150, 0, 0));
}
if (! digitalRead(BUTTON_LEFT)) {
pixels.setPixelColor(NUMPIXELS/4, pixels.Color(150, 0, 0));
}
if (! digitalRead(BUTTON_DOWN)) {
pixels.setPixelColor(NUMPIXELS/2, pixels.Color(150, 0, 0));
}
if (! digitalRead(BUTTON_RIGHT)) {
pixels.setPixelColor(NUMPIXELS*3/4, pixels.Color(150, 0, 0));
}
if (! digitalRead(BUTTON_IN)) {
pixels.fill(pixels.Color(50, 50, 50));
}
It's in sync with what I assume is the flashing of the LEDs
Can't figure out where the sound is coming from though.
Ok hold on
Oh also that was supposed to be an if not buttons I tried the while to see what it would do.
Ohhhh ok.
hardy hornet
if not buttons[0].value:
print("enter")
pixels.fill((100, 100, 100))
if not buttons[1].value:
print("up")
pixels[0] = (150, 0, 0)
etc.
queen smelt
That's acting like it does inside the loop.
yeah
Ok!
Other than the weird audio interference, I got it.
queen smelt
I have no idea.
It's when I press the center button and the LEDs go white.
They're pulsing faster than I can see
but I can hear something
and it doesn't get louder if I move the Feather setup closer to my face
Or I got bitten by something and now I can hear LEDs?
hardy hornet
it's probably aliens. or the feds parked out front.
queen smelt
Oh those guys. Ugh.
hardy hornet
just put on a tinfoil hat
queen smelt
On it.
hardy hornet
you can try your same code with auto_write on and remove the show
just see what it ends up looking like on the neopixels
queen smelt
Yeah giving that a try
hardy hornet
it may be "flickery"
hardy hornet
yah, it' because you're spamming updates all through the loop
instead of just once at the end
queen smelt
Got it.
Leaving it on.
Much better.
Thank you!
Oh
There's a delay in the sketch
Do I need one in the CP code?
hardy hornet
hmm....try adding that and going back to auto_write on
queen smelt
Now it flickers more slowly 😄
And the others flicker slowly too
So that answers that.
hardy hornet
ok. so the spammy updates are noticeable.
queen smelt
Yeah.
hardy hornet
in that case the delay is only needed to prevent spamming the serial prints
queen smelt
I'm not worried about it.
hardy hornet
otherwise fine to read and update the neopixels as fast as possible
