number of ICs, config problem #6
Comments
okey figured it out, i had to skip 6 first leds from first control strip, now i have different problem, digits are mirrored or reversed, for example when i manually set digits to 5 5 5 5 they are showing as 2 2 2 2 one way or another, but digits like 1 3 are displaying fine |
Hi,
You have chosen the correct numbers for most variables, but for the
NUM_FIRST_LEDS, it should still be 3, and you just need to make sure you
have 3 LEDs at the beginning.
What did you put as the length in the WLED app in the LED preferences
configuration? In your case, it should be (9*7*4) + 3 = 255, 9 LEDs per
segment, 7 segments per digit, 4 digits, plus the 3 in the beginning.
For the mirrored or reversed, did you follow the arrow correctly on the LED
strips? Also double check the wiring.
Thank you,
Reda

Hey, i am trying to make that digital clock, i have all segments already wired and set up. I'm using ws2812b leds which have 1 IC per 1 led, what number should i put here and in wled led count configuration to make it work? Every segment has strip containing 9 leds.
const int NUM_OF_SEGMENTS = 28; // Number of total segments the whole display contains.
----> const int ADDR_LEDS_PER_SEG = 9; // Number of addressable LEDs (ICs) per segment.
const int SEGS_PER_DIGIT = 7; // Number of segments that make up 1 digit.
const int NUM_DIGITS = 10; // Number of digits each 7 segment digit can display, 0-9.
-----> const int NUM_FIRST_LEDS = 9; // Number of first set of 3 addressable LEDs which are only used to set colours.
When im trying config as shown above only 3 segments and first strip that controlls the colours work
