I have 300 addressable LEDs in total on 3 strings of 100 all connected together with the data cable from an ESP8266. I have power running to each string from a power supply and that is running fine. I have tried several examples from the FASTLED library, but the lights work up until the same spot, which is at about 225 LEDs of the 300. I have the data line from the ESP connected to the first string, that is then connected from that string to the next and so on. How do I boost the signal or what else is required to get past this issue?
Forgot to mention that the LEDs are on a custom ordered build with 10 inches between them making it 300 x 10” = 3000” or 250’ feet in total length.
