buhler Posted March 27, 2008 Report Share Posted March 27, 2008 i searched the forum, went through the midi troubleshooting guide twice and still nothing. i can't figure out why the core is not talking to the computer in Mios studio. when i power on the core the LCD states "MIOS v1.9F" and then TK's copyright stuff and then it just says "READY." that's it. i have 8 banksticks connected to the core because i thought that may be necessary but no change. i don't really know what to do. please help. super noob!! :-[PS i'm using a MAC. i'm sure that's probably the problem. ;D Quote Link to comment Share on other sites More sharing options...

Can you give us more information? Which of the midi troubleshooting tests failed? (at least one of them did, or it'd be working!) What midi messages do you receive when you power on the core? Please copy and paste the logs or screenshots (preferably the logs) of all your tests. Quote Link to comment Share on other sites More sharing options...

Please copy and paste the logs or screenshots (preferably the logs) of all your tests.that's the problem... i'm not receiving any midi messages from the core. i would paste the logs but they're blank. i honestly don't know a thing about this part of the process. TestProg1 and all 10 TestCore's passed with flying colors. i have to go and buy some more LED's today to be able to test the MIDI out but TestIN1 and 2 passed and 3-7 plus INOUT will be done once i have more LED's. i know it's a MIDI problem i just don't know how to fix it.

jaywar Posted March 27, 2008 Report Share Posted March 27, 2008 Sounds like the problem I had... could be a bad optocoupler. It's a pretty easy/cheap thing to try. Also, I use a mac, and once I fixed the optocoupler, no more problems! Quote Link to comment Share on other sites More sharing options...
buhler Posted March 27, 2008 Author Report Share Posted March 27, 2008 really? a bad optocoupler. i'll give it a shot. thanks. Quote Link to comment Share on other sites More sharing options...
stryd_one Posted March 27, 2008 Report Share Posted March 27, 2008 really? a bad optocoupler. i'll give it a shot. thanks.The same problem has also recently (in the past two weeks) been caused by a working opto inserted backwards, a dodgy midi interface, a bad upload to the PIC, a short circuit, and a driver configuration problem. Feel free to just throw parts at the problem at a guess, but if you don't get lucky, then you could waste time and money.went through the midi troubleshooting guide twice and still nothing.TestIN1 and 2 passed and 3-7 plus INOUT will be done once i have more LED's.Hmm. If it's a bad optocoupler, then you'll find out in the midi troubleshooting (that you said you'd done, and then said you hadn't)... Do those tests, and you'll be well on your way. When you've done those tests, you'll have logs regardless of your core's working status. The logs, and the other results of the tests, will indicate the source of your problem(s).May I direct you to my signature, rules 1, 3, 5 and 6. Hopefully 8 will not be far away :) Quote Link to comment Share on other sites More sharing options...
jaywar Posted March 27, 2008 Report Share Posted March 27, 2008 point taken! just offering my experience. I seem to remember this part causing a lot of problems in the past. But obviously, many things could cause this, so by all means, follow the tests, post the logs, etc. Just something to consider. Quote Link to comment Share on other sites More sharing options...

Hopefully 8 will not be far away :)i'm trying not to seem too stupid but it's all so new. i actually barely have a grasp on what MIOS studio is doing seeing as i don't do well will the software/programming side of things. i didn't mean to make it sound like i did the entire troubleshooting guide. that was my bad. i'm using all SmashTV's kits so i know that i don't have to program the PIC. are the "logs" the MIDI in and out monitoring screens? because if they are, i'm getting absolutely nothing in the MIDI IN screen. i have to wait a couple days until the optocouplers come in so i'm gonna have to try other things until then. i totally appreciate your guys' help and i don't want to turn you off to helping me... i'm trying my best to follow your steps Stryd... i took note of them long before i got to this point, just in case. :) i'm gonna start over and then get back to you. thanks again. one other thing, should i unplug the Banksticks and if not, should i build and connect the 2 sid modules before doing this or is only the core necessary?

jaywar Posted March 27, 2008 Report Share Posted March 27, 2008 Definitely go through the midi trouble shooting guide, 2 or 3 times (or more) carefully. I went through it several times and took a break (sometimes a few days or weeks break can really help with problem solving—and your social life!). Then I got back to it someone suggested the optocoupler and it worked. But stryd_one is right, you don't want to start throwing tons of parts at it until you're satisfied that you've isolated the problem. Which is key: isolate the problem. I would say, the biggest thing is to be methodical and don't jump ahead of yourself until you're satisfied with your test results. Take notes if you need to. Keep at it, it may take a while but eventually you'll get it. Quote Link to comment Share on other sites More sharing options...
buhler Posted March 27, 2008 Author Report Share Posted March 27, 2008 thanks for the encouragement man! it makes me feel less lame. :) i just tested the MIDIOUT from the core with an LED and i got nothin' i.e. no blinks, nada. that makes me wonder if indeed it is the Optocoupler. i'm now going to move onto the MAC side and go through the PC section of the tutorial. i'll post back soon.is MIOS studio and MIDIOX the same thing? i've downloaded a thing called MMJ, another called SysexLibrarian and another Java plug called Plumstone V1.3. is that all i need? maybe i'm missing something on the software side that is causing the problem.

jaywar Posted March 27, 2008 Report Share Posted March 27, 2008 Go through the software setup carefully. I don't remember my exact setup, but I remember installing plumstone, I used Mios Studio for uploading to the core and I think I also used Midi Monitor to see what was going on in general with midi and my computer.

buhler Posted March 27, 2008 Author Report Share Posted March 27, 2008 OK. i've gone through the troubleshooting guide all the way up to TestIN7 which is the standalone optocoupler test. i built the circuit and hooked it all up and i get +5V in both the closed and open positions on the switch. i can only assume that this is at least the problem that needs to be delt with first. i did the MIDI loopback on my Mac and found that the MIDI is in fact working perfectly. when i did the loopback on the core... the LED never went off. in testIN's 3-6 i was unable to get the LED to light let alone flicker and TestOUT1 yielded the same results: no light, no flicker. BUT with the TestIN7. i found that the Optocoupler is most likely to blame do to the fact that whether the switch was open or closed i still read +5V on my multimeter. unless i am missing something, i believe this may be were i need to look to fix the problem... i'm going to have to wait a few days until my new optocoupler arrives, so i'm going to build my 2 Sid modules now and then wait. let me know if i am totally incorrect in my assumtions. thanks for all your help so far guys!

buhler Posted April 3, 2008 Author Report Share Posted April 3, 2008 i would just like to say thanks to you guys before i make you hate me. i didn't mention that i bought my kits from SmashTV and if i had, one of you may have mentioned to me that i did not need to upload MIOS if i had a preprogrammed PIC. anyway, long story short: i'm an über noob and an idiot. i guess if i were having trouble uploading the SID applications then i wouldn't be so lame, but trying to upload MIOS to an already programmed chip, well that's pretty lame. sorry for the inconvenience guys. i'm lame. :-[ :-[ :-[ :-[ :-[ :-[ :-[ :-[ Quote Link to comment Share on other sites More sharing options...
stryd_one Posted April 4, 2008 Report Share Posted April 4, 2008 Well, you don't *need* to upload it, but, you should still receive an upload request and if you try to upload MIOS again, it should work. And no you're not lame. New maybe ;) Quote Link to comment Share on other sites More sharing options...
buhler Posted April 9, 2008 Author Report Share Posted April 9, 2008 Well, you don't *need* to upload it, but, you should still receive an upload request and if you try to upload MIOS again, it should work. And no you're not lame. New maybe ;)thanks for making me feel better stryd. :) i actually borrowed a friend's PC running windows and got everything uploaded. there is something screwy with Mac's... i have plumstone, MIOS studio and one other driver type thing for java that i can't remember and i still couldn't get it to work. the PC picked up the request instantly. i guess Mac's aren't awesome for everything!! i would like to get it to work at some point so i can build more of these projects. anyway, thanks again.
