Welcome aboard man. I noticed you posted in ithe italiano forum also - crossposting is always a good idea for multi-lingual support, but it’s a good idea to post a link to the other thread in each of your threads, so they are cross referenced.
Speaking of good ideas, it would be helpful if you could paste (not type) the logs from mios studio.
It’s probably best if you do not connect any other modules if you are having problems, that makes it easier to isolate the cause of the problem.
I should direct you to the ‘troubleshoot!’ link in my signature
It’s like installing windows 3.11. You have to install DOS before you install W 3.11. Same with Midibox. Upload MIOS first http://www.ucapps.de/mios/mios_update_v1_9f.zip and next upload SID app. You’re using PIC18F*, right? Sou you have to upload 2 apps, not just 1. Are there any questions?
sorry i cant past the errors cause the core is like freezed i cant upload nothing :-[
That’s fine, we need the errors from mios studio. You need a burner to erase the PIC completely, but normally it is not necessary - the bootloader has restrictions in it’s code that prevent you from overwriting it, so it should always remain functional, and send an upload request, which will allow you to reinstall MIOS, and your app.
We’ll start at the beginning - disconnect everything from your core except power and midi - no LCD, no DIN/DOUT/SID/etc
Try to upload MIOS to the core by the usual procedure, and paste the results:
Well, the idea of removing the LCD to test, is that seeing as you see weird glitches on the LCD, maybe you’ve soldered it incorrectly and it’s screwing up the rest of the core…
If you’re not getting an upload request, I’d normally say to start with the MIDI troubleshooting on ucapps… It’s hard to say now, because it was working before, which suggests a working core, but you’ve simply made it impossible to know, by changing too many things at one go. Maybe you’ve fried something through a change, maybe something failed, maybe it was a bad code upload… Mystery. I would recommend you follow and read the link in my signature about troubleshooting, to avoid such problems in future.
Well, you say the core is frozen and you can’t upload, but you mentioned error messages. That doesn’t add up. If it’s truly frozen, it won’t do anything, and that includes returning an error. Can you please describe exactly the error messages to us? Pretend that we have no idea, because we can’t see it. Give lots of detail.
Similarly, you also said something about it giving you a welcome message. If it gets that far, it should have sent an upload request, which takes me back to the beginning of my message - do the MIDI Troubleshooting on ucapps.
And remember to do one thing at once. If you think, that your PSU gives too low voltage, check it, change, but don’t do anything else. If you’re sure, that your PSu works good, check something else. Cause if you’re trying to fix 2 things at once, you can fix a thing but screw another one:) Maybe you should write on your local forum to find someone with uC programmer? You know, I had problems with my core module too. I’m a rather nervous one, so I built another core module (that worked flawless) and then began to debug my old one. I’ve found a cold joint that caused all my problems. Maybe you should check for bad joints? But remember - 1 thing at once!
apologize …I’m analogic and i love schematics , flow charts , lists, i’m a robot!!
