Hi @timb !
Hope you did not try to eat these M&Ms yet…
I also want to use the APA106 LEDs (Neopixels) with built-in WS2811 control IC for “status boards”, setting each LED to a specific colour depending on the applicable status.
I wonder if I can omit the level shifter, mentioned in the library text.
You are obviously not using any 3.3v => 5V level shifter with these “PIXELBIT” LEDs.
Are they 3.3V types? (I could not find them and your above link is broken)
Did you try the “neopixels” also without level shifter?
Has anyone else had issues with too-short delay times on Photons? Various functions take ms as ints, and I’m finding them executing much faster than specified, e.g.:
int flash_delay = 2000;
int flashes = 10;
int final_delay = 20000;
for (int n=0; n<flashes; n++) {
next_time_red = red(next_time_red, flash_delay);
}
red(true, final_delay);
colorAll(OFF, 1);
The flashes are happening at about 2Hz, instead of 0.5Hz, and the final red call goes red and immediately turns off, though the comment for the function call is // Set all pixels in the strip to a solid color, then wait (ms)
I have a first-pass of the technobly library this is based off of running RGBWstrandtest.ino using the pinSetFast() and pinResetFast() changes recommended elsewhere. No guarantees that I got all the color ordering correct – this is a machete hack not anything ready for a pull request yet – but it should work.
###Just updated the NeoPixel library to support the RGBW NeoPixels
Important:
If you have an old app in Build that you are migrating to a Photon, P1, Electron or Core, please remove the NeoPixel library from your app and re-apply it to update the included library to v0.0.9. If you are creating a new app, simply add the NeoPixel library to your app and you will have the latest v0.0.9.
Just updated the NeoPixel library to support the RedBear Duo device
Important:
If you have an old app in Build that you are migrating to a Particle Photon, P1, Electron, Spark Core or RedBear Duo please remove the NeoPixel library from your app and re-apply it to update the included library to v0.0.10. If you are creating a new app, simply add the NeoPixel library to your app and you will have the latest v0.0.10.
Tested on RedBear Duo in Particle Internet Button (WS2812B) and with RGBW NeoPixel ring (SK6812RGBW), compiled in Build IDE with v0.2.4 Duo system firmware. Also tested via command line with the CLI.
Tweaked rgbw-strandtest.cpp to add all required prototypes for local build/no-preprocessor-build
If you have an old app that you would like to update please remove the NeoPixel library from your app and re-apply it to update the included library to v1.0.0. If you are creating a new app, simply add the NeoPixel library to your app and you will have the latest v1.0.0.
While the NeoPixel library was submitted by Particle the FastLED library is not.
Currently we have to hope for an update by the original contributor.
I’ve filed a GitHub issue on his repo, but he can’t commit to any ETA yet.
Yeah, there was somebody else in the FastLED community forums on G+ asking about it a week or two ago.
I’ve thought about just writing a library of work-alike functions for some of the most common things from FastLED which you could then use with NeoPixel. It probably wouldn’t be anywhere near as optimized, and it probably wouldn’t integrate the same in a lot of places. But it still might be useful for people who are more used to that lib.
This ported Neopixel library does not support strip.fill?
I need to be able to set the ENTIRE strip to one color QUICKLY not waiting for it to set individual pixels one by one from one direction but the whole strip all at the same time.
strip.fill(10, 0,0,50);
strip.show();
Error I am getting… ‘class Adafruit_NeoPixel’ has no member named ‘fill’
The FastLED library can do this no problem using
fill_solid();
But I need to do this using NeoPixel library.
Any help anyone can give me would be GREATLY APPRECIATED!!!
Thank you!
When you set each individual pixel separately but only call strip.show() when having that done, all pixels will change (near) simultaneously anyhow.
There also is an example that shows how to do that
// Set all pixels in the strip to a solid color, then wait (ms)
void colorAll(uint32_t c, uint8_t wait) {
uint16_t i;
for(i=0; i<strip.numPixels(); i++) {
strip.setPixelColor(i, c);
}
strip.show();
delay(wait);
}
