LenweTasasartir Posted February 28, 2008 Report Share Posted February 28, 2008 Thank You! I've connected 470 Ohms in serial with pull-up resistor making it's resistance smaller. Everything works fine!Starting upload of mios_v1_9f_pic18f452.hex Hex file contains code in MIOS range, forcing reboot!

stryd_one Posted February 29, 2008 Report Share Posted February 29, 2008 I haven't found them! I think, it could be moved to "Misc"... Click link to ucapps page, scroll down, you'll see MIDI Troubleshooting near the bottom... orClick the search link, type midi troubleshooting, hit 11 is LINK TO MIDI ISSUESorStart at forum front page, scroll down to Testing/Troubleshooting, and you'll see the above link as a sticky thread.Seems easy enough to find where it is ;) It takes some time of course .... Only took a minute for me to find it three different ways, but of course I'm familiar with the site... that's why it's important to read lots, it's not just the stuff that 'sinks in', it's also the stuff that gives you a 'feeling' of where things go... It's like getting to know someone's kitchen; I wonder where this guy keeps the beer glasses? Probably the same place he got that wine glass from ...I've connected 470 Ohms in serial with pull-up resistor making it's resistance smaller.Serial makes it larger, parallel makes it smaller. Anyway, now we know that it was a dodgy midi interface, What kind of midi interface is it? I don't suppose it's USB, and running off a hub? (I'm trying to think about why it may be underpowered aside from just being faulty... maybe it can be fixed) Quote Link to comment Share on other sites More sharing options...
matrigs Posted February 29, 2008 Report Share Posted February 29, 2008 yeah in my case in fact the midi interface was creating the failures. Quote Link to comment Share on other sites More sharing options...

stryd_one Posted February 29, 2008 Report Share Posted February 29, 2008 But it's most usefull for new users ;)Nah that's what I said - it's most useful for new users to read,read,read, so they get used to where things go, and can easily find it when they search,search,search. A stickied thread in the troubleshooting forum and a link from the front page at ucapps and a solid search hit is about as good as the coverage could possibly be, and the most appropriate place. I'm the first to admit that sometimes it can be hard to find the little bit of info you need, amongst all the info around here - but this is not one of those times. You just didn't search hard enough.I'm using DIY interface, connected to gameport, but the problem was at CORE module side.No, the problem is with your midi interface - you just changed the core so that it works with your broken midi interface. Now they're both gimpy ;) Quote Link to comment Share on other sites More sharing options...

ris8_allo_zen0 Posted March 1, 2008 Report Share Posted March 1, 2008 Lenwe, that's the same schematic I've used for my MIDI adapter too. (it's also the most famous, available on the 'net since one decade I think).But by my side the problem was lying in the master keyboard, unable to communicate to the Core. Link between Core and the adapter was always been OK. Eventually I had to modify the Core so it could also read from the keyboard.Now I got rid of my DIY interface because of other issues. I'm very happy (even with Linux!) using a Midisport 2x2. Quote Link to comment Share on other sites More sharing options...
nILS Posted March 1, 2008 Report Share Posted March 1, 2008 Just goes to show that stryd_one is correct and the problem is not the core but the interface ::) Quote Link to comment Share on other sites More sharing options...
stryd_one Posted March 1, 2008 Report Share Posted March 1, 2008 That's based on MMA's schem:Yeh... ris8 mangled his midi interface to match his mangled keyboard, and had to mangle his core to match the two of them.... Seeing as you don't have a keyboard that forces you to mangle things, you should try and fix the interface (although the real problem may be the joystick port) so you don't have to mangle every core you make.
