You mean with my new output driver? Do you have pixels connected to it? Did you try setting it to say 500 pixels?


Yes, the new output driver is working like a champ as long as I keep the OPI in Master mode.  It does not like being a slave, LOL.

I'v now tested on a Raspberry Pi B and Pi 3. Few tweaks added to my fork. It's now ready for you to merge and tweak yourself.


Looks like there's still a 'global' limit even the Pi 3 can handle. Tried 2100 pixels total (700 per port x 3) and the Pi 3 chocked and crashed. Looked like a kernel panic.  Reduced to 1500 pixels (500 per port x 3) and it's running stable. 60% CPU usage just running the fastest chase on the testing page.


Shame the PWM pin shares with the second SPI port on the Pi 3, we might have gotten 4 pixel ports otherwise...

The timing required by the rpiws281x library might be too much to handle when the 3rd output via SPI is added.  I glanced over the merge request and will try to get it in as soon as possible.
