I have problems with my LED Matrix.

I built it upon the Schematic of Fairlightiii's pcb but with just 8 Encoders and LED Rings.

 

By turning one of the Encoders all LEDs around the other Encoders go on, but the LEDs around the Encoder i turn don't. 

And the brightness of the LEDs increase by Turning all the Encoders to 127.

 

Don't know where to start searching. 

The PCB is correct, i checked that. 

 

this ist my config .ngc for testing:

 

RESET_HW
LCD "%C"
LCD "@(1:1:8)OLED1"
LCD "@(2:1:8)OLED2"
LCD "@(3:1:8)OLED3"
LCD "@(4:1:8)OLED4"
LCD "@(5:1:8)OLED5"
LCD "@(6:1:8)OLED6"
LCD "@(7:1:8)OLED7"
LCD "@(8:1:8)OLED8"

Any Ideas?

Sounds like an inverted selection.

 

Are you using ULN2803 as sink drivers?

Then you would have to use following configuration:

DOUT_MATRIX n= 1  rows=8  inverted_sel=1  sr_dout_sel1= 7  sr_dout_sel2= 0 sr_dout_r1= 8 sr_dout_r2= 9

 

Or you are not using an ULN2803, but the polarity of the LEDs is wrong?

Then try:

DOUT_MATRIX n= 1  rows=8  inverted_sel=1  inverted_row=1  sr_dout_sel1= 7  sr_dout_sel2= 0 sr_dout_r1= 8 sr_dout_r2= 9

Hi TK.

Wonderful! it was the Inverter... The Polarity is equal to fairlightiiis pcb.

But i designed just 15 LEDs because for Audio Panorama functionality i want a Middle "single" LED. 

Now the Middle point is decreased to left. I expected it to increase to right because the LED missing there. (my LEDs are like fairlightiii's from left to right) Is that because of the Inverting? 

Thanks a lot!

inverting != mirroring

You have to create your own LED_MATRIX_PATTERNs for 15 instead of 11 (or in the lre8x2 setup: 16) LEDs.

Do i understand right?

Mirroring = It lets the LEDs go "ON" in the opposite direction (shift-register Outputs go Low in Opposite direction as without)

Inverting = It swaps the row and selector shift registers

No, inverting means, that the signals on the DOUT output will be reversed.

Means: instead of 1, a 0 will be output, and instead of 0, a 1 will be output.

This is required for the case that somebody swapped anode/cathode of a LED, or to revert the polarity change of a sink driver.
