funkfinger / strandtest.ino
Created September 16, 2015 03:52
Adafruit Neopixel strandtest.ino on an ATtiny85 - set the fuses for it to work!
#include <Adafruit_NeoPixel.h>
#define PIN 0
// Parameter 1 = number of pixels in strip
// Parameter 2 = Arduino pin number (most are valid)
// Parameter 3 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)

ATTiny85 3 channel software PWM to drive RGB LED
// based largely on Atmel's AVR136: Low-Jitter Multi-Channel Software PWM Application Note:
// http://www.atmel.com/dyn/resources/prod_documents/doc8020.pdf
#include <avr/io.h>

#define CHMAX 3 // maximum number of PWM channels
#define PWMDEFAULT 0x00 // default PWM value at start up for all channels
