HELP please... Core going crazy !!!!

dizzu · April 22, 2007, 3:06pm

I wired core 1:1 to gameport using an already programmed PIC 18f452.

I set up sound card ( midi port shows as MPU 401 ).

When I turn on the core very strange things are shown on MIOS studio;

Once in a while I get Sysex message: F0 00 00 7E 40 00 01 F7, but this is very rare.

I checked all voltages, installed another new PIC that I programmed myself but still nothing.

Also when I connect test led with midi pins it flickers every 2 seconds.

I tried uploading MIOS but still nothing is working.

PLEASE HELP

Are you able to test the gameport with another MIDI device? (e.g. a MIDI keyboard)?

And how is your core module powered? From the PC, or with a seperate PSU?

Best Regards, Thorsten.

dizzu · April 22, 2007, 9:37pm

I never tried anything else with this gameport. Can it be cable length? I am using 1mtr 4 core shielded.

I am using a separate PSU, I checked voltage and it is exactly 5Vdc.

AbortRetryFail · April 23, 2007, 12:48am

I just finished mine up 5 minutes ago and it did the same thing. I found out what it was: POWER

I was running it off a 9v battery with about 8.1v in it, it would go positively apesh*t on the MIDI out port just like that for about a minute then it would just sit there dead. I stuck a brand new 9v on it and it booted right up.

Now i’ve got to get some apps on there to test it out.

dizzu · April 23, 2007, 8:20pm

I tried on batt, AC psu, DC 12V, DC 18V… same probs.

I also tried shorter cable and thicker.

My prob is not power, I think it’s either the midi cable or the PC!!!.

Cause I tried 2 soundcards Audigy and MPU 401. Exactly same probs.

I am wiring midi out directly through a 220R into midi in and vice versa.

I am ordered a new midi in - midi out cable hopefully receiving it by end of this week.

I will post results.

dj3nk · April 23, 2007, 10:56pm

dont you have a midicable in your audigy? theres another optocoupler inside, so youll need one. its the same circuit which is on the core so you can duplicate and diy it. Taking the SubD isnt possible when you want to use midi in AND out. perhaps try to unplug your midi-in of the core, just to check if a proper upload request will be send.

dizzu · April 24, 2007, 1:31am

No I don’t have the cable for the audigy. I tried using midi out only of midi core but never received an upload request alone.

Only like this now;

It happens like this all the time; quite strange is that when I put an led on midi out of core it flashes every 2 sec.

I will test a midi cable soon as I said in my last post.

Any idea from where I can buy the AUD_EXT cable/adaptor for audigy?

Thanks

I wouldn’t even bother connecting the core until you have confirmed that your midi cable works.

Have you tried wiring the out to the in, and sending a note from mios studio? You should receive the same data you send.

dizzu · April 24, 2007, 3:04am

yes, that works perfectly.

I am now trying to use rs232 ltc module. I installed roland driver.

But mios not showing anything.

Any settings?

stryd_one · April 24, 2007, 5:01am

I assume you’ve altered the PIC ID so that it will use the LTC?

How do you mean

mios not showing anything.

?
