  2. Connecting RGB LEDs

    in MIDIbox NG

    Posted

    So you think that the 0,1V, that I measure on the not-active outputs wouldn't be enough to let the LEDs glow?

     

    I don't want to rewire the whole array. Just the last LEDs of every row, which goes to D0:D3 on SR1 and the last LED of every coloumn, which goes to D0:D7 of the other SRs. I don't plan to rewire the connections between the LEDs.... I hope I don't have to, because this took me two days...

     

    Anyway.... I will get back to you as soon as I rewired the connections and setup the NGC.

     

    Thanks!

  3. Connecting RGB LEDs

    So your suggestion is, to connect all LEDs to the two DOUTs? Maybe I should start, setting up another matrix of LEDs, which is much smaler.. lilke 4x4 or so. Just for testing and before connecting all the 64 LEDs again to the DOUTs.

     

    I want to change to ribbon cables so I need to rip up a few.... or a few more.... cables the next days. Got a gig on upcoming saturday so I don't think I will be able to do this tomorrow.

     

    But the problem that I reported remains: I think, because of the small voltages at the outputs, which are not active, the LEDs will light up low. But that's not what we want, is it? I thought, it's possible, to switch all LEDs completely off. Where does these voltages come from?

    Okay!

    Thats my code:
     

     

    RESET_HW

    LCD "%CHello World!"

    EVENT_BUTTON id=2  fwd_id=LED:1  type=NoteOn key=36  lcd_pos=1:1:1 label="Button #%3i: %3d" button_mode=Toggle

     

    I connected a DIN to my core with a button attached. This one works fine. Right after the DIN I put my DOUT but I removed the ULN.

    Now I'm able to switch on / off the outputs of the first SR by changing the "fwd_id=LED:x"-number. I measure 5V when I press the button. And 0V when I press it again. So... it seems everythings fine here...

     

     

    //edit: I put back the ULN into his socket. I'm able to switch on / off the outputs of the ULN. The output that's "active" has 1,2V, the other have those small voltages like in the picture above... like 0,1V. By pressing the button again, everything goes to 0V. I'm wondering, why the other outputs also get small voltages... this should be 0V or did I miss something?

    Hey,

     

    thanks for the hints.

    You are right. I will solder off all the wires and use ribbon cables. I'm busy for today so I don't have much time to test. But I will come back to you shortly.

     

    But to answer your questions:

    Yes, this one is SR1. I disconnected all other DOUT / DIN modules from this one in the picture.

    I also checked the cable on J1. The cable makes a half twist and goes not 1:1. This should be correct. The 74HC595 are getting their 5V...

     

    I really want to get this machine running in the next days. So I hope, I don't strain your attention to much.

     

     

    Thank you very much!

    As I understand it, without button_mode=Toggle, you should see 5V when key#36 is pressed and 0V when it is released.

    With button_mode=Toggle, press the key ->5V, press the key again ->0V, and so on.

    Either way we want to see 0v and 5V on the output of the DOUT under midi control.

     

    The 5V at the output of the SR / the input of the ULN are always there. It doesn't matter, if I press a key or not.

     

    I need to replace "type=NoteOn key=36" with "type=cc cc=1" to get something out of the ULN. I get 1,2V out of the ULN to D7 by pulling up the CC1 fader in MIOS Studio. I never got 5V out of the ULN. If I leave "type=NoteOn key=36" I measure 0V with pressed AND depressed #36 at D7.

    Hey!

     

    I disconnected the rows from the DOUT but leave the coloums connected. Here is what I did:

     

    I used this code:
     

     

    #row 1
    EVENT_BUTTON id=1  fwd_id=LED:1  type=NoteOn key=36 button_mode=Toggle

    #row 2
    EVENT_BUTTON id=2  fwd_id=LED:2  type=NoteOn key=37 button_mode=Toggle

    #row 3
    EVENT_BUTTON id=3  fwd_id=LED:3  type=NoteOn key=38 button_mode=Toggle

    #row 4
    EVENT_BUTTON id=4  fwd_id=LED:4  type=NoteOn key=39 button_mode=Toggle

    #column 1 red

    EVENT_BUTTON id=5  fwd_id=LED:9  type=NoteOn key=40 button_mode=Toggle

     

    I measured the input of the ULN, which is 4.9V. I measured the outputs = 0V. I pressed key #36 and measured the outputs again = 0V.

     

    I changed the code to:

     

     

    #row 1
    EVENT_BUTTON id=1  fwd_id=LED:1  type=cc cc=1

    #row 2
    EVENT_BUTTON id=2  fwd_id=LED:2  type=NoteOn key=37 button_mode=Toggle

    #row 3
    EVENT_BUTTON id=3  fwd_id=LED:3  type=NoteOn key=38 button_mode=Toggle

    #row 4
    EVENT_BUTTON id=4  fwd_id=LED:4  type=NoteOn key=39 button_mode=Toggle

    #column 1 red

    EVENT_BUTTON id=5  fwd_id=LED:9  type=NoteOn key=40 button_mode=Toggle

     

    I measured the outputs = 0V. I pulled up the CC1 fader in MIOS Studio and measured again. D7 is at 1,2V. All the other outputs have a small voltage too. See picture attached.

     

    I'm really not sure, where to look for the mistake. I also tested it with another DOUT module. Same here. Also it seems, that button_mode=Toggle isn't working at my side. I also tried to again upload MF_NG without any results.

    Thanks for your help.

     

    I tried, what you were suggesting.

    At first I copy&past your code into my NGC. By pressing #36 nothing happened. Also pressing #40 all LEDs stay dark.

    I replaced "type=NoteOn key=40" with "type=cc cc=1". When I use the slider, I can switch on and off a array of 4 LEDs. This is not working on the rows. If I replace "type=NoteOn key=36" with "type=cc cc=1", nothing is changing. It's still not working...

     

    I measured the rows and it's at 2,8V.

    I'm suggesting you take a step by step approach to discovering what is going on with your LED array.

    I've made some very specific suggestions.

    It is up to you if you want to do it, or not.

    Maybe you got me wrong?! Of course I want to do it, but I'm not sure, how to code that...

    I'm not so much experienced with coding. So please excuse my "bad coding".

     

    I tried just this

     

    EVENT_LED  id=1  type=CC cc=16 rgb=0:0:15

     

    Nothing happens, when I use the slider. Same with keys... everything is dark.

     

     

    //edit: I did draw a diagram, that shows, how I connected the LEDs. The color of the boxes are the rows, the number is the led.

    As you can see in the picture attached, I'm able to set the color for every single LED.

     

    Because my wiring was very (!) time consuming, I don't want to rip it all up. And I don't get exactly, what you mean. Maybe you can explain more into detail?

    I really appreciate your help!

    And another question:

    I now connected all red and green LEDs.

    I have a problem: I can't swich the LEDs off. I tried rgb=x:x:x to 0:0:0 and also tried to set the value to 0. The LED are still on... they are low, but they are on....

    Okay, here we go!

     

    I now connected 4 rows with 16 LEDs per row to D0:D3 of SR1. For now I just connected eight (8x4) of the green LEDs to D7:D0 of SR2 to see, if it's working.

    I connected the DOUT with the core. The first SR has no resistors, just bridges. SR 2-4 are equiped with ULN2803. I put a 82Ohm resistor to each output (so, 8 resistors).

     

    I tried this code:
     

     

    # In this demo we configure individual brightness levels for the LEDs

    RESET_HW

    LCD "%C@(1:1:1)RGB Demo #1"


    # In the SR configuration we assume that the DOUTs are directly connected to J8/9 of the core
    # they emulate led functions
    DOUT_MATRIX n=1  rows=4  inverted=0  sr_dout_sel1=1  sr_dout_r1=2  sr_dout_g1=3  led_emu_id_offset=1001

    # note: actually the sr_dout_sel1 in DOUT_MATRIX could be removed,
    # since DIN_MATRIX already outputs the selection pulses there
    # this is just for the case that somebody copy&pastes the definition...

    But... no lights... nothing happens......

    any suggestions?

    I'm really not much into SysEx, but just a short question:
    Is it possible to send SysEx from a computersoftware (like MAX or plogue bidule) to the core, which changes the LCD message? If yes: Is there a kind of "sysex-creator" for text?

    I'm asking because Mainstage is not able to send tracknames (in difference to logic). I want to use Plogue Bidule instead to do this after every patch change. Will be a lot easier, than programming patches on the MB_NG.

    As mentioned in a thread (MB_NG) I've tried to connect my expression pedal to the analog ins of the LPC.

     

    It seems to work, but I've got jittering values (about cc-value 122 in one direction, 6/7 in the other) . I tried to connect a resistor between 3.3V and the pin on the exp-pedal. Same here. I saw, that there is a "calibration" function in the menu. When I try to calibrate, the monitor gives me a LOT of informations. But I can see no change if I pull down the exp-pedal. At this point the application (or MIOS Studio) hangs and the only thing I can do, is plug off the USB from the computer and restart the application.

    Is there a way to manually calibrate the pedal? Because now the monitor says, the min_value of the analog_in is 0 and the max_value is 255.

    Thanks for your help!

    Another one: How to connect an expression pedal to the LPC? It has a stereo jack, so I assume, I need to connect GND to GND, tip and ring to a separate analog-in on the LPC. But how to assign them in the NGC so it behaves like one controller?
