ATtiny85.... going slightly insane

[baffled2023]

Hello

I have an ATtiny85. Factory new, so I burnt the bootloader on at 8mhz.

Trying to run a short strip of ws2812 LEDS using Fastled and it just won't work. Its a timing issue.

I loaded Blink and it flashed madly fast, so I burnt the bootloader again a 1 Mhz and it seems correct now.

But, the code (it's a simple Fastled demo routine) won't load due to incorrect timings.

Can anyone advise what frequency to burn and then what to select to get the timing correct?
Thanks

Is your sketch in asm or c?

Fastled and it just won't work

as expected. use some decimated lib, suitable for attinys.
