  1. uploading MIOS V1.9F via MIDI for MIDIbox CV

    OK, I've just got back from vacation.  I'll check out the single suggestion I received today.  thanks stryd_one
  2. uploading MIOS V1.9F via MIDI for MIDIbox CV

    I've uploaded the main.hex from lcd_interconnection_test_v1b.zip found on: http://www.ucapps.de/mios_download.html .  I have performed all the pin tests, and my J15 header passes all 11 tests except the one for RS.  I get 0.89v for the RS header, which connects directly to pin 28 of the PIC, which also reads this same 0.89v.  Once again I'm stuck!  I have no idea what is causing the PIC to produce only 0.89v at pin 28.  I'd love to hear some suggestions!

    Thanks for the help, guys!  I'm going through these great suggestions now.  I'm convinced it's a wiring issue, because I rewired it after posting and now it flashes black and goes out.  I'll post my results soon.

    Hmm.  So I plugged all the modules together.  I powered up, and I realized I have no idea if this thing is going to work or not, because I believe the LCD may have been destoyed!  Should the LCD light when powered on?  Mine does not.  ???

    OK, so here is the update:  Most recently TK suggested a software (MIOS Studio Internal Routing) config change may lead to a solution.  Also sineSurfer suggested changing MIDI cables.  I have done both.  Also, my E-mu 1616m has 2 MIDI OUTS and 2 MIDI INs.  I was using MIDI 1 OUT for PC MIDI OUT and MIDI 2 for PC MIDI IN.  I put them both on MIDI 1 and retried Smart Upload, and IT WORKED !  HA HA!!  YES!  I'm going to play with it a little more to see if it can actually do something now, I'll update soon.  Thanks for the replies and the feedback everyone, this has been quite a crazy journey so far.

    Everyone quit their day jobs!  :D

    My MIDIbox CORE module does not work like it should.  Some evidence indicates the MIDI IN pathway is not functioning, even though it passes all the tests.  A bad optocoupler has also been suggested even though it passes all the tests.  After one week of heavy troubleshooting I've concluded my MIDIbox CORE kit has a failure which no active contributer to this thread can diagnose.  I'm writing to the distributer of the kit for any last minute help before replacing it.

    any more suggestions before I order a new CORE kit ?

    BAD LCD? Well, I've continued to hack away at the completely assembled CORE, but to no avail.  The CORE is from a kit by SmashTV, I've gone through all the troubleshooting guides, everything should be working, but the LCD is totally blank, and I've double checked the wiring.  I've seen no troubleshooting guide for the LCD - how do I know if it's burned out?  BAD SOMETHING ELSE? Also, MIOS Studio receives one sysex msg from the CORE on power up, but Smart Mode hex upload does not (never has) start.  When Manual Upload is performed I can see the sysex messages in the OUT window, but I receive no feedback at all from the CORE.  I've gone through the MIDI IN troubleshooting section exactly as recommended by TK, and my results are here: http://www.midibox.org/forum/index.php/topic,13512.0.html it seems to pass the troubleshooting tests, but it is still not working.  HELP! I've gone through all the trouble to build it, it would be nice to see it work.  Can somebody please help me?

    I've been working on this thing for hours.  When the DIN, AOUT, and LCD are all connected to CORE, CORE sends no MIDI SysEx message.  When the LCD is removed, that same single Sysex msg is received by my PC.  Is this normal?  Also, uploading using Smart Upload still does not do anything, I've used Manual Mode several times and rebuilt the .hex file to match my encoder and J5 preferences (building the hex file instructions do not include having to copy p18f452.inc to the directory where make is run, mine failed until I copied it from c:\program files\gputils\header\).  My LCD doesn't display, so I have no idea if this thing is working or not.  I'll go through the LCD information about debugging that component next.  Probably not until tomorrow, I can't work on this any more tonight.  I'll get this thing working!

    I think uploading MIOS may have worked, because I did see reply messages after every packet sent, and also I'm only seeing one sysex message upon power up.  I'm going to continue as if everything is working now, I'll reply to this thread with my result!
  12. uploading MIOS V1.9F via MIDI for MIDIbox CV

    I also get a sysex message from CORE upon power down now. 
  13. uploading MIOS V1.9F via MIDI for MIDIbox CV

    Do my test results indicate user error with the software?  I'm testing it again now, and I no longer get a repeating sysex message from the CORE, just one at power-on.  I don't know what that's all about, I hope I didn't break it!

    TEST IN1: PASS: all 3 resistors have the correct color bands and my multimeter reads the correct resistance value for all of them. TEST IN2:  PASS: I tested the midi ports on the CORE, and they are both wired the same way and have identical placement and polarity.  They are mounted onto the top of the PCB from SmashTV with 5 pins, not 3 as in the figure.  If the rear of the midi port is shown in the figure, then both are reversed.  I mounted the plugs on the top of the PCB as shown in the figure here: http://www.avishowtech.com/mbhp/mbhp_coreR4d.html .  Near the bottom of that page is a figure of header J13; the traces in the figure show how the reversal is accomplished.  I don't think my CORE fails this test because both midi ports are the same and one works.  TEST IN3: PASS: I soldered the LED as pictured in the figure.  With the power on the LED lit right away and stayed lit.  Using MIOS Studio I performed a Manual upload of a .hex file with a 300ms Delay between SysEx messages.  Monitor:IN window continued to show "F0 00 00 7E 40 00 01 F7" every two seconds and the LED flashed OFF each time a SysEx packet showed in the Monitor:OUT window.  I also performed the same test without the LED in place, and the output from the CORE changed!  Monitor:IN window showed many lines of "F0 00 00 7E 40 00 01 F7" and a new message, "F0 00 00 7E 40 00 0E 0B 01 F7". TEST IN4: N/A: LED lin in test 3; I skipped this test TEST IN5: PASS: The LED flashed ON each time a SysEx packet showed in the Monitor:OUT window.  TEST IN6: PASS: The LED turned on when CORE powered up. it turned off when M- of MIDI in connected to ground. TEST IN7: Switch closed: 0.04V Switch open: 5.26V TEST INOUT1: FAIL: I connected my PC MIDI interface MIDI out to MIDI in.  I used MIDI-ox to send/receive a sysex message.  I received the same message.  I then soldered Rx to Tx on the CORE, put the small chip back into the board, and removed the large chip.  I connected the CORE to my PC and sent the same message and did NOT receive it.
