Hey everyone
FastLED library does not work on Arduino Zero
Tried pins 1 2 3 and 12
Code is an example of a library
Test the output signal with an oscill
But no output at all
(Use Adafruit NeoPixel Library
The output is only ~760KHz
Same as not working)
(Using ESP8266 is normal)
Arduino IDE version 1.8.5
Library version 3.18

It looks like it should work, except on pins 4 & 5.

I’ve got a few Chinese zero clones but not used one yet.

@Jeremy_Spencer There is output now.
But the frequency is only 660 KHz
Still not working

@Jeremy_Spencer
Zero output signal:
Data 1 ~ 660 KHz 1.500us
Data 0 ~ 640 KHz 1.572us
Frequency will change
And the wavelength is over 1.25us plus or minus 150ns
Not working
The output signal of the ESP8266 is ~730 KHz period 1.372uS
Frequency is stable
Can work

Can you put your code on gist?

@Jeremy_Spencer The problem has been solved
Detailed on the github question page
