Fastled: Problem with IC SM16703P

[vecio88]

Hi,
i have a problem with my strep led with IC SM16703P. THis IC not is between the supported chipsets. I have tried to use other chipset but not work well. For example, if i run the example "FirstLight" on the strip , the led turn on in random mode and not with a sequence how is wrote in the code.

how can i solve?

thanks

The SM16703P is not a supported chipset, I will have to add support for it at some point in the future.

+1 for sm16703 also sm16723P(Iout:12mA), thanks!

Has the chip been added since?
If not: are there other libaries that can be used?
Thanks

It has not been added yet - I don’t know if there are other libraries for it or not.

SM16703 is supposed to be compatible with ws2811 which is supported, how ever has slightly different timing requirements. here is a link to a discussion about the differences that may be helpful:

And the Datasheet:

By the way, here in the states Costco has 10 meter strings of these (SM16703) for $29.99

Could not find any working SM16703 Arduino library. It's rather a chip in demand. No idea why some far east LED manufacturers claim that its protocol is compatible with ws2811.

Wow, it's been more than 2 years and still no support for SM16703

[focalintent]

That’s because major work on the library stopped about two years ago because of this - https://plus.google.com/102282558639672545743/posts/JQKcujjaXXC - and no one has submitted a PR for 16703 support.

My 16703 is workable with WS2811 settings. It says 'CC16703 184508' on chip. Maybe from a China Factory.

I have the cc16703 chip and my work around is using Adafruit Neopixel at 400KHz, and it works like a charm. I got a RF controller with my strip, but where is the fun in that.
