[[fadercore_-_fadermodule_for_audio_daw|Fadercore]] 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. {{:fadercore_vlr-meterboard_beispiel_1_kanal_bestueckt.png?600|}} Eagle Files: [[https://github.com/novski/Midibox/tree/master/VLR-8x16LEDmeter]] {{:fadercore_vlr-ledmatrix_unbestueckt_top.png?200|}} {{:fadercore_vlr-meterboard_bestueckt_sideview.png?200|}}\\ {{:fadercore_vlr-ledmatrix_dimensions.png?300|}} {{:fadercore_vlr-meterboard_dimensions.png?200|}} ==== 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]] 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. == The Materials: Mouser == * 3x10pin Header, 517-30310-6002 * 6x10pin Sockets, 517-D89110-0131HK * 16x20pin Header, 517-30320-6002 * 16x20pin Sockets, 517-D89120-0131HK * 20 Wire Ribbon Cable, 523-135-2801-020FT * about 80 Green LEDs, 604-WP3A8GD * about 80 Yellow LEDs, 604-WP3A8YD * about 80 Red LEDs, 604-WP3A8HD Project Order Basket on Mouser: [[http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=5ecf7b4949]] The PCB is available under: [[https://www.vlrlab.com/home/18-ledmatrix.html]] [[https://www.vlrlab.com/home/19-meterboard.html]] ==== 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\\ ENC n=1 sr=1 pins=0:1 type=detented2\\ \\ EVENT_ENC id= 1 fwd_id=LED_MATRIX:1 type=CC chn= 1 cc= 24 lcd_pos=1:1:2 label="^std_enc" LED_MATRIX_PATTERN=1\\ \\ LED_MATRIX_PATTERN n= 1 pos= 0 pattern=0000000000000000\\ LED_MATRIX_PATTERN n= 1 pos= 1 pattern=1000000000000000\\ LED_MATRIX_PATTERN n= 1 pos= 2 pattern=1100000000000000\\ LED_MATRIX_PATTERN n= 1 pos= 3 pattern=1110000000000000\\ LED_MATRIX_PATTERN n= 1 pos= 4 pattern=1111000000000000\\ LED_MATRIX_PATTERN n= 1 pos= 5 pattern=1111100000000000\\ LED_MATRIX_PATTERN n= 1 pos= 6 pattern=1111110000000000\\ LED_MATRIX_PATTERN n= 1 pos= 7 pattern=1111111000000000\\ LED_MATRIX_PATTERN n= 1 pos= M pattern=1111111100000000\\ LED_MATRIX_PATTERN n= 1 pos= 8 pattern=1111111110000000\\ LED_MATRIX_PATTERN n= 1 pos= 9 pattern=1111111111000000\\ LED_MATRIX_PATTERN n= 1 pos=10 pattern=1111111111100000\\ LED_MATRIX_PATTERN n= 1 pos=11 pattern=1111111111110000\\ LED_MATRIX_PATTERN n= 1 pos=12 pattern=1111111111111000\\ LED_MATRIX_PATTERN n= 1 pos=13 pattern=1111111111111100\\ LED_MATRIX_PATTERN n= 1 pos=14 pattern=1111111111111110\\ LED_MATRIX_PATTERN n= 1 pos=15 pattern=1111111111111111\\ \\ Im using my VLR-8oDisp board to show the Values of the encoder.
