Question about dot matrix

Other Hardware LEDs and Multiplexing
5

now it works :slight_smile:

    shiftOut(clockPin, dataPin, LSBFIRST, matrix);
    shiftOut(clockPin, dataPin, MSBFIRST, ~(1<<i));

I did not pay attention to it

must be

    shiftOut(dataPin, clockPin, LSBFIRST, matrix[i]);
    shiftOut(dataPin, clockPin, MSBFIRST, ~(1<<i));

thanks a lot for your helps paul
