 +==== BOM ==== 
 +BIll of Material ​         
 + 
 +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]] 
 + 
 +== The Buttons == 
 + 
 +I thaught a long time about how to make a Button PCB that does not explode in material cost. 
 +The best solution was to buy rubberbuttons from Sparkfun and cut them because the with of Fadercore is fixed by the minimal width of 8 Oleds side by side... 220mm in width / 8 makes a 27.5mm grid. What a pity that the Sparkfun pads are premade with a 25mm grid...  
 + 
 +you will need two of them: 
 +[[https://​www.sparkfun.com/​products/​7835]] 
 + 
 +== The other Materials: Mouser == 
 + 
 +  * 2x10pin Header, 517-30310-6002 ​                                                                                                                  
 +  * 5x100nF,​594-K104K15X7RF53K2  
 +  * 2x10k Network, 774-77061103P ​        
 +  * 3x220R Array, 652-4816P-T1LF-220 ​                                                                                         
 +  * 1x74HC165D, 771-HC165D652 
 +  * 4x74HC595D, 771-74HC595D ​                                                 
 +  * 24xLED RGB, 604-WP154A4SUREQBFZW 
 +  * 24x1N4148, 512-1N4148TR 
 + 
 +Project Order Basket on Mouser: [[http://​www.mouser.com/​ProjectManager/​ProjectDetail.aspx?​AccessID=1f42b04e6d]] 
 + 
 +The PCB is available under: [[https://​www.vlrlab.com/​home/​20-3x8but.html]] 
 + 
 + 
 +==== How to get Started ==== 
 + 
 +If its your first SMD soldering you can follow this on t1:58 : http://​www.youtube.com/​watch?​v=5uiroWBkdFY 
 +I recommend to not buy solder paste, instead buy some flux-paste like this on Mouser: 590-8341-10ML 
 + 
 +==== Prepare the PCB ==== 
 +Start with the SMD parts and then go on the the conventional parts also on the Bottom side. 
 +Then go on with the Topside and the LEDs. 
 +Check the Connections with a Lens. 
 + 
 +==== Prepare the Connection ==== 
 + 
 +Connect the core on J8/9 to J1 of the VLR-3x8But board. 
 + 
 +==== Test it in MIOS ==== 
 +\\ 
 +To make it work with MIOS .NGC  File we need to know how the shift-registers are connected.\\ 
 +\\ 
 +**Inputs:​**\\ 
 +1# Switch Columns ​ 1-8\\ 
 +\\ 
 +**Outputs:​**\\ 
 +1# ROW Outputs ​    ​1-6\\ 
 +2# RED LEDs        1-8\\ 
 +3# GREEN LEDs      1-8\\ 
 +4# BLUE LEDs       ​1-8\\ 
 +\\ 
 +Assuming that the VLR-3x8But 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"​\\

 +LCD "​@(6:​1:​1)OLED6"​\\ 
 +LCD "​@(7:​1:​1)OLED7"​\\ 
 +LCD "​@(8:​1:​1)OLED8"​\\ 
 +\\ 
 +# In this demo we configure individual brightness levels for the LEDs from EVENT_BUTTON events\\ 
 +\\ 
 +LCD "​@(1:​10:​1)RGB Demo #​2"​\\ 
 +\\ 
 +DIN_MATRIX ​ n=1  rows=4 ​ sr_dout_sel1=1 ​ sr_din1=1 ​                    ​button_emu_id_offset=1001\\

 +\\ 
 +# These button functions forward their value also to LEDs\\ 
 +# it's possible to set the rgb levels in the button event, it will be forwarded as well!\\

 +Im using my VLR-8oDisp board to show the Values of every item. 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)}

 +For any Comment or Question: Forum Thread???
