Well, here's where i'm standing. I measured the midi out from my usb adapter, and found out that the voltage is very low to make the optocoupler run. I'm taking one of these ways: I'll find an optocoupler that needs less input signal to run, or i'll get a soundcard. Thanks a lot for your help, i'm very grateful. And again, i'll let you know how things are around here.

my mistake, sorry. i noticed that message changed because of the device id...

Ok, tried to upload via sysexbox, and it seemed nothing changed. I try the to upload via miostudio, and the message has changed. it's now Received unexpected MIOS SysEx message = 00007E400001F7 expected = 00007E4001. Have i given a step forward or backwards?

But if i use a basic config, it should always be 0, right? I came to the conclussion that my core is not receiving midi data. I tried to upload mios via sysex, using hex2syx and sysexbox, and it happens exactly tha same. going to check the rx path again. Thanks a lot for your help, i'll let you know how it worked later

But i have read around that if i dont change it, it will always be 0, right? As i'm a newbie, i tried to stay away from that stuff, cuz i'm starting with a basic kit, and i won't use more than one core.

I use mios_v1_9f_pic18f452.hex, which i think it's the last version. The thing is, when the upload starts, shouldn't the "upload request every 2 secs" stop?

i will join the chat. I meant miostudio reported te upload, but when i reset the core, nothing new happened

Tried it, nothing happened. Still the same...

Ok, nils. You say that i should only plug the core's midi in, and send mios w/o smart mode?

hi dave, i'll check the led thing, though i did something similar. I'll tell you later how it went. I'm using 6N138. Thanks a lot!

It cancels the upload, whether i use smart mode or not, on the 16th msg!

Hi nILS Podewski. I did check both the optocoupler and the tracks, several times, 4 to be exact. Also bought another pic, and programmed with bootloader, still happens the same. I also uploaded w/o smart mode, and happens exactly the same! Thanks, regards

Hi people, how are you? My name's Julian, and i'm a newbie from Argentina. I'll start by telling you all about my problem I made my own pcbs, according to the files I downloaded. I soldered all the stuff, burned the bootloader to my pic 18F452 with the pic burner (design also listed in main site). Till this point, we're cool. Now, the problem comes when i try to upload mios with miostudio. I plug a power supply, nice, strong and filtered. Got my 9V, got my lcd, one line black and the other blank. And when i start checking midi in and out pages, i realized that it keeps sending and receiving upload requests every 2 secs. This, i think it should stop at the time mios starts uploading, but it doesn't, making the upload to cancel on the 16th message! I tried every single thing listed on the forum, and every test, midi, core, everything, but it keeps working this way. I have some expertise in electronics, that is soldering, making pcbs, measuring voltages and all the stuff, so i managed to check the pcb, compare it with the circuit, i also checked for solderings, and i also went through all the board, and measured every single track for shorts. I dont know where to head to from here, so please, i need some help. I would really really appreciate it. Best regards for all
