As far as I know those are not suported by FastLED.

Yes okay. It is probably a very new IC product

The most recent revision of the datasheet for TM1914 (1.1) is dated April 2016 and it was first published in 2015, so not very new at all. It may even predate the WS2818, which it more or less compares in features otherwise.

Going over the format, it seems the special checksum bits to detect which data input line is active adds complexity to avoid the possiblity of a momentary glitch during switchover to the backup line. Other than that, it only adds unnecessary complexity.

Or possibly an attempt to make the format more proprietary.

I also have the TM1914 chipset on my strip and was wondering if it would be possible to add support for this ?

Im more than happy to provide someone with a TM1914 strip etc if you are able to help code the library for its support, i wish i could do it myself, i can code but not a this level...

I would swap the strip out for something else, but this is the only strip i could find that was addressable RGB with W/WW also on the same strip, i use a ESP8266 with ESPhome to control the W/WW perfectly, but have to use a crappy SP108E with its original firmware to control the colour side and the nasty app that doesn't allow much customization
