I am wanting to control a RBG LED Strip with an ATTiny13. I have found a tutorial using the Arduino IDE to programme this but in all the examples I have found the LED strips have 4 cables i.e. power and then RBG. Mine has only 3. I thought I could use a normal Arduino example but they all use FastLED which won't work with the ATTiny. I am not sure where else to look.
Thought I found what I am looking for GitHub - cpldcpu/light_ws2812: Light weight library to control WS2811/WS2812 based LEDS and LED Strings for 8-Bit AVR microcontrollers. but alas not.. will not fit on ATTiny13.
Have you tried the Adafruit Neopixel library?
Alas that does not work either. Found tiny tinyNeoPixel but get error that tinyNeoPixel.h is not installed and when I add it I get an error that their is a duplicate.
