been dealing with ray for 7 years only ever had some faulty 2811s about 3 years ago witch he replaced but he tells me there all tested prior leaving the factoryHas anyone had any problems with lights from Ray Wu's store? I have just got a delivery of pixel strings and they are not working. Previously bought strings work but put the new ones in and nothing.
jstjohnz on DIYC said:World Semi has made a significant timing change to the WS281x series of pixel chips. The required time between data frames was previously specified as 50us (and was often actually about 12us) and is now spec'd at 250us for some of the newer ICs.
No firmware changes were required for the Falcon boards, so even the very oldest firmwares will work with the latest 2811 chips.
Same.Only issue I've had so far are some pigtails that were wired incorrectly, but that's no big deal as long as you test first!
