First let me answer some questions to Michael: Yes, I burned v1.2 bootloader myself. I burned it with Mikroelektronika EasyPic development board. I ordered componets from Mike's midishop. I ordered 2 PIC's, just in case. I also tried by disconecting that ground wire from midi out of the core - but that didn't help. And now, something completely diferent: MIOS is on the PIC!!! LCD says "Ready." How? So far I used dell notebook with extern sound card - TASCAM US122 As I saw on this forum, sometimes sound card could make problems, so I decided to try it on other card - Sound Blaster Live on my PC - it worked first time. Now I'm killing my self because I didn't try this before, and saved you and myself a lot of trouble. Anyway - I'm not still sure if the sound card is the problem - maybe it is different java installed. I'll experiment some more this weekend and when I see what was the reason, I'll post it on forum to save someone else of loosing so much time. Anyway, I'm very happy that mios is on the PIC, and I'm going to programm it now for a while. Thank you all for all suggestions, and please forgive me if I missguided you. I'll be back Ante

Answer to moebius : - I tried by disconecting whole midiout - that was easier for me. Then I used Mios Studio to upload mios without conformation from the core - just sent packages every 1000ms - That didn't help. But I'll try to disconect just the ground toonight. Thanks Ante

Of course it is ok. Answers: I bought stuff from Mike's shop. Midi plugs are not mounted - they are connected with 20cm long wires to the core. I checked and rechecked every single connection. I'll take picture toonight - I'm at work now. Java version: jre-1_5_0_06-windows-i586-p.exe Hear you Thanks Mark

Yes I tried with 9V as well as with 12V 2A - it seemed all right to try with that - all the voltages were ok - 5.06V Also I forgot to mention that I have two PIC 18f452- and two opto couplers - on all combinations I get the same behaviour. So I guess it is not problem with those components. Thanks Ante

Hi Mark. I'm a bit confused about your last post. I did everything from that procedure before. I'm pretty much sure that there is nothing wrong with procedure, nor with Mios Studio - because I tested it with that loopback test - hex file that I burned on pic. Every message that was sent from midi studio to pic was again received in mios studio. That should mean that Mios Studio works. Anyway, I tried MidiOx - and the similar thing happened - pic didn't respond in right way - like it was def or sth. Don't think that I'm ungratefull or something. I'm very happy that I have a place (this forum), where I can get help, and please continue to help me with any suggestion. :)

I tried other power suply's, but no luck: 9V battery 2A power adapter. I also tried midiox - same trouble - bootstrap loader just keep emitting that upload request message. I'lll put here just parts of log - whole log would be to big: SYSX: F0 00 00 7E 40 00 01 F7 0003C1FC 2 -- F0 Buffer: 8 Bytes System Exclusive SYSX: F0 00 00 7E 40 00 01 F7 0003D140 2 -- F0 Buffer: 8 Bytes System Exclusive SYSX: F0 00 00 7E 40 00 01 F7 000C2313 MOX 7 F0 Buffer: 1184 Bytes System Exclusive SYSX: F0 00 00 7E 40 00 02 01 00 01 00 0D 7B 62 5F 00 45 0F SYSX: 7F 7F 76 39 7C 0F 57 35 4F 61 3D 33 6B 01 73 21 1E 5D SYSX: 26 1A 0A 0D 49 71 50 4E 6A 00 2D 04 7A 71 07 68 3C 56 SYSX: 42 3E 43 03 45 6C 7F 78 2C 2E 6B 7E 11 00 38 39 7B 4F SYSX: 57 45 4F 5D 3D 3E 6C 7D 6F 6B 77 67 6F 1E 5F 2E 3E 7B SYSX: 75 01 70 17 6F 28 13 01 3F 7A 41 38 0C 07 54 24 00 5C SYSX: 71 3C 1F 7D 6B 0B 62 7F 6E 78 5F 37 7E 79 45 7B 7F 77 SYSX: 5C 2F 57 7F 3E 62 40 7E 0B 7E 14 09 70 60 31 20 5F 00 SYSX: 48 00 08 07 35 4D 6F 14 50 05 34 02 74 07 3E 60 2F 61 SYSX: 32 5E 52 1D 40 67 43 05 57 4F 24 19 59 06 60 1D 4F 13 .... ....

every two seconds. I'm sorry that it wasn't power related issue, because I hopped that it was. I'll try toonight with pc power supply anyway. If you see something in this log please tell mee (it is midiox sysex log).

Ok I'll try to find some better suply too - how about pc power supply - connected at J2? It is 500mA - I forgot to write that in last post. Also I disconected LCD after initial trouble - so it isn't causing trouble. Thanks Ante

Hi Mark Thanks for the encouragement. No there is no other message - only that upload request every two seconds. My power source is cheap (4-5Euro) power adapter that can give diferent DC voltages on output. I tried it on 6V and 7.5V setting on J1 pins in the core. When it is set to 6V - it gives 5.06 at the core, and when it is set to 7.5V it gives something above 5.1V. I'm not ready to give up just yet :) Ante

Hi Michael Which suggestions - I thought I did it all: If i didnt make right connections - neither of two loopback tests would work. Yes - I get stuff out of mios studio, with that loopback test. Actually I didn't try midiox - I'll try that toonight. Thanks again for your help Ante

I tried all tests from Midi Debug section at ucapps that doesn't involve extra parts - like extra led. I specially tried two loopback tests: 1. conecting Rx and Tx when PIC is not in its case, and that one worked fine: all that I sent from mios studio I also received in mios studio. 2. uploaded sw_loopback_test hex file with hardware burner on pic. This loopback also worked fine: all that I sent was received in mios studio. Yesterday I was checking resistance with multimeter when voltage is applied to the core and I saw two possible strange things: 1. Resistance between Rx and Tx is about 6k 2. Resistance of that Diode D1 on MIDI IN was 4k in one direction, and 16k in other. Is there something wrong there? I tried to diferent optocouplers, and tried uploading without one. In all cases there was an error: received unexpected upload request, because bootloader (I burned bootloader_v1_2_pic18f452 because v1.1 that came with PIC from Mikes shop showed same signs) sent that upload request signal every two seconds. So it seems that PIC hasn't received anythigng. But when I try to measure voltage between Rx and Tx - it is very low when nothing is sent, it is about 100mV when bootloader sends that upload request, and it is about 2V when Mios studio sends packages to PIC. That also looks strange to me. Is it? I think the problem is not related with power supply because even though I use cheap adapter - it is connected on J1 and the voltage is 5.06V all the time, with and without the PIC - and with and without optocoupler. It is measured on all points suggested by ucapps. Thanks for all help so far I'm open for any suggestion

I wonder have you been able to fix that board from Mike's shop? I'm having exactly same problems now and don't know what to do. Please help if you have solution. Thanks

Here I am again. I removed similar topic from programming section on request of audiocommander. Sorry about that, but as you see, nobody answered me here on this subject. I searched this forum little more, and I saw that problems I'm having could be due to bad optocoupler, wrong resistor on optocoupler, bad power, etc. I'm going home now, so I'll check those things. Thanks

I'm sure that I uploaded pic burner, because I get that sysex message every 2 seconds - that says "Pic burner is alive" I cannot upload anything but burner (nor MIOS, nor app) - with mios studio - all I get on "IN" window in mios studio is that "alive signal" from pic burner. Because there is no confirmation message from burner, I think neither package gets through to pic. I thought that I could do all of that with hardware burner, so I did like this: burned pic burner, then burned mios, than burned app. But it seems that every burning overwrites everything that was before on pic. So I'm stuck with mios studio to burn mios and app, and I cannot get it working. I also tried it without lcd, but MIOS won't upload neither. Let me just repeat that I tried burning that loop test - with hardware burner. When I tried it in Mios Studio - everything works ok - whatever I send to pic, I get in mios studio in "IN" window. This means that all midi conections are ok, right? Please help, because I don't know what else to do. How should I upload MIOS? Thanks

Hi Here is some more info: I uplaoded MIOS with hardware programmer, but nothing works. On LCD upper row is fully drawn (there are no characters - just every character rectangle is drawn), and second row is empty - nothing is drawn. When I try to build simple mios application that writes something on lcd or sends midi event - nothing happens. I tried puting it in diferent places, like in Init() or DISPLAY_Tick() or MPROC_NotifyTimeout(), but nothing happens - I get nothing at In window of MIOS Studio. BUT when I upload sw_loopback_test hex file - than everything works - everything that I send from mios studio, I get back instantly. I hope that this helps. Please somebody, help me Thanks

I'm true newby to this midibox stuff, so if you could please help me I would apretiate it very much. I bought stuf from Mike's shop, and soldered everything, checked all voltages, conected PIC, installed mios studio, but I cannot upload MIOS. Bootstrap loader works fine I think because it keeps sending me that Sysex message every 2 seconds. My conclusion is that midiout of Core module works fine, but when I try to upload hex file of newes MIOS, I keep getting the same error message in Mios studio: Error: received unexpected upload request. In "IN" window of Mios studio, I keep getting the same Sysex message - so I think Midi In of the Core module isn't working. Midiout of of my sound card works fine because when I start upload of hex file - led light blinks. Also I checked voltage between two pins of the midi cable that are conected to core - the voltage changes in exact moment when packets are sent. Polarity is correct. I checekd everything from the ucaps page about midi troubleshooting. Also I bought new optocoupler 6N138, but nothing helps. Only one strange thing I noticed is that resistance on diode is about 6k in one direction, adn about 18 k in other direction - should it be infinite (this is when core module is not connected to power source)? I'm pretty sure that Midi IN of the core isn't working, but I cannot figure why. Please help Antimon
