Hi yall! Just got started and having trouble with using fastLED with a lightblue Bean. Getting the neopixel lib to work, but nothing is showing when I’m using fastLED. Anyone with experience?

#include “FastLED.h”
#define NUM_LEDS 23
#define DATA_PIN 3

CRGB leds[NUM_LEDS];

void setup() {
FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
}

void loop() {
leds[0] = CRGB::Red;
FastLED.show();
delay(30);
}

The bean uses a different port to pin mapping. I’ll have to do up definitions for it to be supported.

Oohhh. So it wasn’t me being stoopid atleast…

Please do! The beans “built-in” bluetooth functionality is very interesting!

also. Thanks!

Pull the latest version of master@HEAD - I just checked in support for the light blue bean’s pin layout, in theory

I’m not familiar with github lingo but I downloaded the .zip again and reinstalled the library.

And now it won’t compile^^
Here are the errors if that’s any help:

Ah - weird - the bean doesn’t support that? That’s annoying. I just added a fix in for that - so re-download.

Works! Thanks!
Will write here again when I’ve done more than lighting up the first led…
