  1. A request of Local Help (London UK)

    Hooray for DIYWH*)!

    *) DIY With Help

    I hated asking for help!

    I've ordered a new set, so hopefully shout be able to trouble this one better later.

    I can currently upload hex to it and the LCD responds, but with uploading the 128 app I get this on the LCD:

    $$6_G$et$$$g=$$$

    oN|5$

    NICE!

    I'll see what happens when I get the new kit from SmashTV.

    But if theres any suggestion on this I'll try it.

    Thanks

    I am upset at myself for having to ask this, but I've hit a dead end with my MidiBox. I've had the Pic Core up and running and a DIN sending out messages, although to many of them! Now I can't seem to get it to respond, although I can upload hex to it etc...

    If there's anyone in London or even the UK that would be a kind enough soul to give me a hand on this, I'll be forever greatful!

    I know its a pain in the arse thing to ask, but I just don't want to waste money on this and am thinking of just buying a new kit from SmashTV (mine is from MikesMIDIshop).

    Thanks for your time.

  5. MIDIbox64 configuration (UPDATE - In DIRE Need of Help!)

    in Testing/Troubleshooting

    Posted

    Arghh! I double checked everything today before getting back to you properly. I did mean DINX, sorry about that ;)

    Ok so connecting QH to ground (and also releasing) writes midi messages to MIOSStudio IN Monitor. If I leave it like that with IC1 out and connect say R9 to VS on J5 nothing happens in the In Monitor...

    This is really doing my head in now, I just want to get to a stage where I can trigger some midi events properly :P

    I will be buying a new core at some point for the second controller, but would really like to problem solve this one instead of chucking it. The other Dinx I made also has the same problem! I think it's wired up properly, but maybe I messed up the pull up resistors which are hard to 100% check in the images.

    Any ideas anyone? I'm about to cry!

    Ok I had a chance today to test it and this is the output I get if I just short one of the DIN pins to ground (It will just constantly cycle if I keep it shorted).

    00000000023283 ms | [97 54 7F] Channel 8: Note On C6 velocity: 127

    Thanks nILs

    I'll check it out tomorrow, but my initial thoughts are that shorting it does the same thing as I tried that originally and I believe it was the same behaviour. The buttons I'm using are just shorting the connection as theres no mechanical elements, it just connect ths vs to the vd etc.

    I'll let you know more tomorrow, but I think this is correct.

    Thanks for getting back to me

    Ok i've scanned every single post in this category to no avail!

    Does anyone know if this is just a configuration problem or possibly a hardware problem? I wouldn't imagine it to be hardware as I've checked all the joints/tracks and the buttons are responding, just sending too many messages.

    Here's the diagram of my button pad that I'm using. Ground is the two lines in the middle, each row is connected to a single sil header.

    Thanks for any help

    Thanks TK, as always! I'd searched everywhere and never saw that page...

    I finished up a custom PCB tonight based on the sparkfun button pad boards with just one row of 4 buttons and tested it. If I plug it into J5, J6 or J7 etc they work fine (as long as I haven't pressed the first button before-hand), so I can just skip J3 with the Bank menu as I only need 40 buttons in total.

    The only thing left is that when I press and hold the button down, it just keeps sending the MIDI message over and over again, which is not what I need. I want to press it down and it sends the message only once until I let go and press it again. There's a bit in the asm that says quality of button, I think it's set to 32 with 0 being high quality. Would you consider this type of button high quality and is it anything to do with why it's sending so many messages?

    I'm searching the forums for an answer to this, but haven't found it yet. Starting to see the end of the tunnel, but I'm sure it'll throw a few things in my face before I get out the other end.

    Thanks for all the help again again...

    P.s. Attached is the board before etching.

  12. MIDIbox64 configuration (UPDATE - In DIRE Need of Help!)

    in Testing/Troubleshooting

    Posted · Edited by MONSTA

    Hey all! I finally managed to get everything together over the weekend and get my midibox64 triggering stuff on my mac. I currently only have a DIN module connected to the core, so have grounded all the AIN pins etc and it's connected over USB to the GM5.

    I've worked with both an edited configuration and the default, but with the same results so far. If I make a connection between the DIN J3's pin D7 and Vs it'll say something about the Bank's etc on the LCD, but I can still assign that to a MIDI command in Traktor, yet none of the other pins will work, even if I set the number of buttons to 4, 8 or 32 in the asm config. I've also had a look at the section that deals with the bank menu buttons, but nothing seemed to correct.

    How can I go about changing the config to just make all 64 buttons be MIDI triggers and forget about the banks? The way I've done the layout means that I won't have to swap the MIDI layout at all.

    Any help would be amazing! Even if you just have an asm to look at that works with a similar setup.

    Thanks

  14. HELP! Think I've bricked the Core!!!

    in Testing/Troubleshooting

    Posted · Edited by MONSTA

    Hey Guys/Girls,

    Ok I've gone through all the checks and they passed. I couldn't check the ground of the power supply of J3 (see diagram), the one at the top, as I couldn't track it down on the board, but everything else returned 5v.

    Anyway, while connected to a 9v AC/DC adapter the core returns 5.05V at J2 as it should (and an LED connected to J12 will flash every few seconds). But if I connect it up through the GM5 it only puts out about 1V at J2 and the LED at J12 doesn't flash any more, yet the power out (J7) of the GM5 is outputting 5V. Is there anything I should change in the core's power handling etc?

    I was about to purchase a few new cores, I need at least one more anyway, but I don't think that'll help at this stage, so any help, as always, is very much appreciated.

    Thank you

    Christian

  15. HELP! Think I've bricked the Core!!!

    Thanks LyleHaze

    I did the MidiLoop thing using just the GM5 and it worked (although the LED is still not working, could this be down to the resistors I used?). I just sent an LCD message from MIOSStudio and it received it back.

    I'm going to do the troubleshooting page now, but one thing I've noticed is that the LCD screen wont light up unless I connect the out to the out (guessing it's something to do with ground...). If you look at the attached gif, you can see how I've connected them up, which I believe is now correct, but there is no response from the screen. Should I hook them up as I've done, but cross over the ground line?

    Sorry for all the questions, I'm just a bit lost at the minute and need to get back on track.

    Thanks

  16. HELP! Think I've bricked the Core!!!

    in Testing/Troubleshooting

    Posted

    Sorry can I just confirm with someone that my wiring is correct of the GM5 to the Core (I don't think it is)?

    Should I be considering the GM5 as a MIDI Interface, so the MIDIOut of the Core goes to the MIDIIN of the GM5? I think I've wired the In>In and Out>Out...

    I'll be going through the troubleshouting in a few hours when I get home.

    Fingers crossed I can find out whats wrong with it and fix it!

    Thanks

  18. HELP! Think I've bricked the Core!!!

    I think my Pic is dead! I had it communicating through MIDI cables connected to an AXIOM25 keyboard. I did a bit of fiddling and think I wrecked one of the MIDI ports I was using as when I tried uploading a Hex file it gave me a MIDI Error and the LCD went blank afterwards...

    Now I've hooked up a GM5 (not sure if its wired properly, can you check attached image, the midi wires are twisted a half turn), but have tried every combination. It shows up on OSX in MIDIRouting, so think it's working fine. Nothing I do will bring it back to life and even turning the LCD pots doesn't have any effect even though its lit, is this cause there's nothing being displayed? I'd have still thought there would be some change!

    In MIOSStudio I get:

    timestamp [unknown] | SysEx: F0 00 00 7E 40 00 02 00 00 00 00 00 00 F7

    Any help would be amazing! I'm completely lost!

    Thanks

    Christian

    P.s. On a side note, the GM5 seems to be ok (shows up on the computer and powers the LCD) but the LED I've hooked up to it doesn't light up. Is this meant to be on whenever it's connected to the computer? Cause thats a bit of a worry if it is!

  19. Can Pots Be Wired Like This?

    in MIDIbox HUIs

    Posted · Edited by MONSTA

    OK here's the new design. This time is two layers, Red on top, Black on the bottom.

    Looks like what other people have been doing, so think it's ok, but just checking. It'll be my first attempt at a custom PCB so I expect it to go horribly wrong! LOL. Will be trying it this weekend, so just checking if this is 100% right.

    Thanks

    Monsta

    P.s. Does it matter which way vcc and vss are wired in? Or is it only the middle pin thats of any importance?

  21. Can Pots Be Wired Like This?

    in MIDIbox HUIs

    Posted

    I am about to start creating my own PCBs and was wondering the best way to wire Sparkfun Pots. I've seen the way people have been wiring pots here and they chain the vs and 5+ separately. Can I just chain 4 together with one loop going from 5+ through all the pots and back to vs (see image)? Also, can you wire these either way or are they polarity dependant. I apologise if my terminology isn't correct and you can understand what I'm saying.

    Thanks

    Niietzhe

    P.s. I like the new Forum! Nice one!!!

  22. Cant Upload Hex anymore... HELP!

    in MIDIbox Tools & MIOS Studio

    Posted

    Thanks for your help!

    Has anybody got any idea how to go about this? Can it be done with software wiring in MIOS studio, or is it a hardware thing? I'm currently running it through an Axiom25, but have the GM5 chips here, so I'll have to get those soldered up...

    I never upgraded my girlfriends computer to SnowLeopard, so I'm going to try it on hers tomorrow which should be the same setup as last time.

    Thanks Again, I'd be completely stuck without help on this one!

  23. Cant Upload Hex anymore... HELP!

    in MIDIbox Tools & MIOS Studio

    Posted

    Hey everyone,

    I have just come back to this project after a few months off. Previously I had uploaded the MIOS to my 64Core, currently it shows this on the LCD:

    [int] N ........ (squares with the first one flashing)

    Reverb # 1  64

    I am now on a new instal (OSX Snow Leopard) so did everything from scratch again, this time having to use Mandolane for Java support (demo). MIOS Studio seems to work ok, being able to send messages to the LCD screen, but trying to upload Hex doesn't work. If I tick "Wait for upload request before starting upload" it never gets accepted, nor sends anything over to the core...

    Any ideas of how to get this going? It's worring me a bit.

    Thanks for any help.

    Christian
