When searching for Digispark support it seems that this hasn’t been implemented yet…
But there are indication that it could be used?
Have a digispark connected to, what i think, is a 2811…
Bought a year ago on ebay “Waterproof WS2801 WS2811 Full Color/RGB LED Module Pixel Exposed Light Sign Lamp”
Trying the blink test and added the line
volatile unsigned long timer0_millis = 0;
(Can’t compile without this)
It compiles and loads but I do not get any blink. Always on.
changing the number of led’s in the init does make a difference.
The color is always “white”.
Has anyone a working demo with the digispark?
Are you using digispark or digispark pro?
Either way, you should use FastLED3.1 branch, define NO_CORRECTION 1 before including fastled.h, and you will have to change pin definitions for digispark pro in platforms/avr/fastpin_avr.h (I’m not sure if the pin mappings are correct for the standard digispark but I seem to recall getting it to work a year ago).
If you look at the pinout for digispark pro (http://3nipp02i1lqr3e844s4d6w4f.wpengine.netdna-cdn.com/wp-content/uploads/2014/04/digispark-pin-out-board.jpg) you’ll see the yellow pin number and the orange port / pin numbers. fastpin_avr has mappings between those with the _DEFPIN_AVR macro. Digispark is attiny85 and digispark pro is attiny167.
Actually, scratch that. If you got the pixels white then you probably got the right pin. Maybe switch around ws2811 / ws2801? The former is 3 wires, the latter is 4. How many wires does the sign have?
It’s only 3 wires so ws2811 should be the right one.
Have got it to work with neopixel library… but not as fun as Fastled 
Digispark pro or standard?
Grab the latest 3.1 branch (even if you already did) - I just checked in the pin definitions for the digispark and the digispark pro as well as a fix for the compile error.
Works great!
Tested blink and fire… runs without any problems.
Can i contribute with anything, on the more hw side?
Do like the Digispark concept of a small unit with easy access of usb.
Think i will add CAN network to that concept as we at work always need
small adapters…
