Hi
I have get some SK9822 (http://www.rgbledcolor.com/) led,
it is a 4 wire integrated digital rgb led with one data cable and one independent clock,
similar to apa102,
I am not sure about this,
so could I use the same code as apa102 (http://www.rgbledcolor.com/sale-8995240-5050-full-color-rgb-apa102c-built-in-ic-smd-led.html),
or anyone have new code for the sk9822 (http://www.led-color.com/upload/201604/5050%20SK9822%20LED%20Chip.pdf),
thx
From the datasheets I was able to find (http://www.instructables.com/id/Compare-SK6822-WS2813-APA102-SK9822/), the SK9822 uses the same communications protocol as the APA102, but supports a much faster transfer rate and seems to be completely synchronous (ie, no low limit timing constraints). My conclusion is that an APA102 driver would correctly operate an SK9822 strip but significantly slower than is possible. The converse is not true, a driver tuned to operate the SK9822 at the higher (or lower) data rates would fail to operate an APA102.

I have got the datasheet about the sk9822 (http://addressable-led.com/Products/SK9822-LED-Chip.html) and apa102 (http://addressable-led.com/Products/),
the sk9822 is about 4kHz and the APA102 is about 19KHz,
SK9822 led (http://www.normandled.com) has the same procotol with apa102 led,so they can use same code.
SK9822 LED datasheet is http://www.normandled.com/upload/201605/SK9822%20LED%20Datasheet.pdf
