  1. SEQ V4 LED's

    in MIDIbox SEQ

    Posted

    HI,

    I recently done a SEQ V4 (Wilba) which goes like a train, all is working very well but I would like to know if there is a way to lower the brightness of the LEDs through programming...

    Thanks a lot.

    but you get a MIDI event whenever a ground connection is done (and removed)? Just like if you would push a button?

     

    I get a midi event only on pin D7

     

    You notice this, when DIN module is connected, right?

    What happens if the DIN module is not connected, and you repeat this test?

     

    Yes without DIN is correct, On when I connect and Off when I disconnect.

     

    And please also do the test with the single 74HC165, because it seems that with a single chip no continuous note off/on will be generated, right? Or does this mean, that they won't be generated if all digital inputs (D0..D7) are connected to ground?

     

    Best Regards, Thorsten.

    Right, with the single chip no continue on/off if DO..D7 is connect to ground.

     

    Thank you.

     

    Regards.

    tested and.....

    without 74HC165 "no midi event"
    With the first 74HC165 assembled and all the pins grounded "No midi events"

    With the DIN module connected and J8/9:SI  directly connected to Vs I receive just some events "only note on" than no additional events.

    but when I disconnect the cable again continuos signal of note  off/on :-(

     

    Thank you.

     

    Regards.

    Hi Duggle,

    I did a test, I only tried with the slot J3, I started to put in ground from D0 and so on and at the moment that I put on ground D6 data cycle stops "NO EVENTS"
    Regarding the DIN "R5" I loaded 8 network 10k (obviously with the poles in the right place) and 4 capacitors 100nf, I hope this board do not need more resistor....

     

     

    Tnx a lot.

     

    Regards.

    Hi,

    I tested everything following the schematics and everything seems to work fine, all voltages are correct, at least the ones described (+3.3 V +5 V-)

    and each IC is in the correct direction.

    Also tested resistance, ok.
    About the computer I use Mac but I don't believe the problem is on the driver.
    The thing  I need to understand is why even without plug the DIN the led2 of the LPC remains continuously red, I think this is a clear sign that the problem lies in the core of the LPC but where?

     

    Thank you.

     

    Regards.

    Hi,

    about your answere :

     

    the red led on the LPC17 core is lit, when some kind of data is processed (like the hdd led on a computer). If there´s a short on the DIN module this would be normal since it processes data continously (impulse from din -> midi data out).

     

    The red led is continously lit even without DIN..... and I begin to believe that the short is on the core :-(

    I tried with your code but same problem, practically is like an open flow of data streaming, any event that I assign to a DIN (and I tried with 2 different DIN) back as a loop on the midi monitor, below a link for a screen shot of the Mios so you can see the data message.

    I did also a test on resistance (R9) on the core but it seems this is not the problem.

    If you have an idea about this problem I would be eternally grateful.

     

    Tnx a lot .

    Hi,

    I think it is also a short, on mios in default NG I receive continuous signals of buttons and related notes.

    I tried to do a test with a simple Hello.NGC but same problem, mios appears on a continuous data stream "chn # 1 note on/off C1" of course the code is : EVENT_BUTTON id = 1 = LED fwd_id: NoteOn key = 1 type = range = 36 0:127 lcd_pos = 1:1:1 label =" Button #% 3i:% 3d "

    Another thing that seems strange to me is that the red LED is continuously lit on the LPC1769 ..... this is right?

     

    Tnx a lot for your help ;-)

    Hi,

    I'm having trouble with DIN R5, just insert the ribbon on J1 and I receive on midi in an avalanche of messages (Buttons-note on / off).
    I'm working on NG Default but I have tried also with Midio128, same problem. I tested resistance and welding on DIN and it all looks ok.
    Have any of you ever encountered this problem?

     

    Thank you.
