I am unable to get it to work whilst I have no problems with any other addressable LED strips whatsoever. These strips light up white with just power connected, and random flickering colour blocks when data pin is connected - I would appreciate any pointers<br/> P.S. Ground is connected between ESP32 and the LED strip and PSU, PSU is 24v same as the LED strip<br/> P.P.S. Actual markings on the tiny chip is FL1903B 2238</p> <p>Amazon (UK) listing for the strip<br/> <a href=“https://www.amazon.co.uk/gp/product/B0BNDPTFWG”>https://www.amazon.co.uk/gp/product/B0BNDPTFWG</a> </p> <p><a href=“https://preview.redd.it/vansnv4olbab1.jpg?width=1500&format=pjpg&auto=webp&s=fc04ca1abef95f706921ff9d42144d76323e6be9”>The LED strip contains blocks of LEDs, each block is addressable via 1903B IC</a></p> </div><!-- SC_ON --> submitted by <a href=“https://old.reddit.com/user/Distinct-Cockroach26”> /u/Distinct-Cockroach26 </a> <br/> <span><a href=“https://old.reddit.com/r/FastLED/comments/14s4zel/rgbic_cob_strip_1903b_chip_any_luck_with_fastled/”>[link]</a></span> <span><a href=“https://old.reddit.com/r/FastLED/comments/14s4zel/rgbic_cob_strip_1903b_chip_any_luck_with_fastled/”>[comments]</a></span> </td></tr></table>
