number of ICs, config problem

[matitoprzechvj]

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

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 (974) + 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

in my case, its perfectly fine when it is laying cable side up, its showing number correctly and everything works, ofc i need to flip it so then the numbers are upside down, picture attached, is there anything i can do in the code to idk reverse it or mirror, or i need to re-wire everything?

[matitoprzechvj]

Okay, re wired everything and now it works fine, thanks

That's amazing to hear! Good stuff!
