Hi everyone, hoping for a little help.
I had everything working well when I tested it with 150 LEDs before mounting the strips to the TV. Mounted them on and ended up using 132 so the it want quite aligned.
I changed the arduino sketch and the hypercon profile for 132 LEDs and now I only get the yellow startup snake. When I right click in hyperion I get the grabber image just fine, but no response from the LEDs. Tried tweaking just about every setting multiple times and can not figure it out.
Any help would be appreciated. Let me know if there is any more information that could help. Rasp Pi 2, arduino uno, WS2812B LEDs (132 of them).

// to calculate your prefix, the first 4 bytes will never change: const char prefix[] = {0x41, 0x64, 0x61, 0x00, this never changes.
// the next byte is equal to the number of LED - 1 --> (232-1)=231. 231 transformed in HEX. 231 in hex is E7 (use google)
// the last byte is equal to the XOR value of the calculated value just above and 0x55 (byte just calculated (E7) XORED with 0x55) = B2 use this link http://xor.pw/? and in input 1 put 55 and in input 2 put your HEX value.
// some precalculated values to save some time: 178 leds gives B1 and E4, 180 B3E6, 181 B4E1, 182 B5E0 232 E7B2 230 E5B0
