I have the following problem/error verifying the code:

I am trying to upload the fastled blink demo to a digispark 85 board…
the neopixel strandtest uploads and runs , and yes i have fastled v3.0.3 installed…any ideas? myself and my digistump are stumped :slight_smile:

i dunno bout the digispark, but timer0_millis is what the avr core uses.

I’m guessing your build isnt defining the digispark at compile time.

Thank you , I will investigate immediately :slight_smile:

Try the FastLED 3.1 branch - there’s a bunch of platform compile issues fixed on there.

Thank you Daniel , I did as you said and it compiled the fastled code…
