NeoPixelLibrary does not work on ATTiny45

[Maaajaaa]

I tried to run the simple example of Adafruit's NeoPixelLabrary on my ATTiny45 on every pin it doesn't work, no response at all (flashing via ArduinoISP worked well, blink example runs well and strip works with UNO and Pro). I also tried to use the light_ws2812, and use clock_prescale_set(clock_div_1); and capacitors/extra PSU and a pull-up-resitor for the data pin - still not working. Is there anything I can do about that?

Are there any suggestions about what could have gone wrong?

I'm having the same issue with the ATTiny84. Just ran the Blink example and it runs fine.

I figured it out. Using the StrandTest, once I uncommented the following lines it worked. I did install a 16Mhz clock and burned boatloader with that setting. Hope this helps.

//This is for Trinket 5V 16MHz, you can remove these three lines if you are not using a Trinket
#if defined (AVR_ATtiny85)
if (F_CPU == 16000000) clock_prescale_set(clock_div_1);
#endif
// End of trinket special code
