Wordclock doesn't light up right LED's

[shruiik]

Hello there, I have setted up a Wordclock on my new Rpi.

since I have little space for the cables, I wrote a new wiring that looks like this:

Y/X	0		1		2		3		4		5		6		7		8		9		10
0	114	E	113	S	112	K	111	I	110	S	109	T	108	L	107	F	106	Ü	105	N	104	F
1	93	Z	94	E	95	H	96	N	97	Z	98	W	99	A	100	N	101	Z	102	I	103	G
2	92	D	91	R	90	E	89	I	88	V	87	I	86	E	85	R	84	T	83	E	82	L
3	71	T	72	G	73	N	74	A	75	C	76	H	77	V	78	O	79	R	80	J	81	M
4	70	H	69	A	68	L	67	B	66	Q	65	Z	64	W	63	Ö	62	L	61	F	60	P
5	49	Z	50	W	51	E	52	I	53	N	54	S	55	I	56	E	57	B	58	E	59	N
6	48	K	47	D	46	R	45	E	44	I	43	R	42	H	41	F	40	Ü	39	N	38	F
7	27	E	28	L	29	F	30	N	31	E	32	U	33	N	34	V	35	I	36	E	37	R
8	26	W	25	A	24	C	23	H	22	T	21	Z	20	E	19	H	18	N	17	R	16	S
9	5	B	6	S	7	E	8	C	9	H	10	S	11	F	12	M	13	U	14	H	15	R

And my Wiring implementation looks like this:

   class maiks_wiring:

    def __init__(self, WCA_WIDTH, WCA_HEIGHT):
        self.WCA_WIDTH = WCA_WIDTH
        self.WCA_HEIGHT = WCA_HEIGHT
        self.LED_COUNT = self.WCA_WIDTH * self.WCA_HEIGHT + 4

    def getStripIndexFrom2D(self, x, y):
        """
        Mapping coordinates to the wordclocks display
        Needs hardware/wiring dependent implementation
        Final range:
             (0,0): top-left
             (self.WCA_WIDTH-1, self.WCA_HEIGHT-1): bottom-right
        """
        if y % 2 == 0:
            pos = self.LED_COUNT - ((y * self.WCA_WIDTH) + (x))
        else:
            pos = self.LED_COUNT - (((y+1) * self.WCA_WIDTH) - (x+1))
        return pos

    def mapMinutes(self, min):
        """
        Access minutes (1,2,3,4)
        Needs hardware/wiring dependent implementation
        This implementation assumes the minutes to be wired as the last four leds of the led-strip
        """
        if min == 1:
            return 3 
        elif min == 2:
            return 2
        elif min == 3:
            return 1
        elif min == 4:
            return 0
        else:
            print('WARNING: Out of range, when mapping minutes...')
            print(min)
            return 0

Unfortunately, the wrong LEDs or no LEDs at all are lit. Even if I choose another wiring, the correct number of LEDs is not lit. I don't get any errors in the Console and when I debug, by using "print" lines, I get the solution that my mapping runs fine. But I don't get the right output. :(

I'm trying to solve this bug for 3 weeks now, but I can't find any solution. Can someone please help me.

Did you have a common ground for your LED's and your RPI? take a look here: https://github.com/bk1285/rpi_wordclock/issues/110

What is the output of strandtest example ? https://github.com/bk1285/rpi_wordclock/issues/102 https://github.com/bk1285/rpi_wordclock/issues/106

With strandtest example file you can test which LED of your strip is causing an error.
