Standard 220mm wide modules 

===== VLR-8x16LEDmeter =====


A solution to add 8 Meters with 16 LEDs for each Meter.
It contains 2 different Types of PCBs one is the LEDmatrix and the other a slim PCB to mount 16LEDs called meterboard.

Allways look for the cheapest seller, the Price may vary heavy!!!
And look for Local dealers preferred. [[http://www.midibox.org/dokuwiki/doku.php?id=where_to_order_components]]

To make a small and easy to connect matrix over a hole Frontplatte is no fun. Thats why i made myself a better solution. Based on the common DOUT modules it can be connected to 3 SRs.

==== How to get Started ====

The LEDs are mounted to the Edge of the Meterboard to get a very slim form. That makes it a bit harder to solder them but i guess that no one wont be able to do it. 
To solder the Header to the Edge there is a wite triangle printed to the PCB on one side. This Triange has to match with the Triangle on the Header.

==== Prepare the PCB ====
Well you should now by now how to solder Headers... :-)

==== Prepare the Connection ====

Connect the SEL, Row1-8 & Row9-16 with each a DOUT Header. 

==== Test it in MIOS ====
\\
I use a Encoder connected directly to a DIN to test.
Assuming that the DOUT is the first device on the chain of J8/9 we need to configure it like this:\\
\\
RESET_HW\\
\\
LCD "%C"\\
LCD "@(1:1:1)OLED1"\\
\\
# Test D-OUT LEDmatrix board\\
\\
DOUT_MATRIX n=1  rows=8 inverted=1 sr_dout_sel1=1 sr_dout_r1=2  sr_dout_r2=3\\

# Matrix control by a Encoder connected to DIN\\

Im using my VLR-8oDisp board to show the Values of the encoder. You can change it to any other type of Display-setting... lcd_pos=6:1:5 {6=Display number : 1= X-axis : 5= Y-Axis (row)}
