nILS Posted August 19, 2003 Report Share Posted August 19, 2003 Hi!When I test my SID (Core stuffed with 16F) with the SID_V2 test program, I get that wonderful chord at startup. ;D After that, I should according to µcApps be able to play notes on Channels 1-3. Whenever I sent notes to the core, all I get's a clicking sound. One "click" for note on, another one for the note off event. ??? Has anybody ever come across the same problem? Any ideas?

TK. Posted August 20, 2003 Report Share Posted August 20, 2003 Hi nILS,maybe you've changed the sound parameters via CC? However, your SID is working now! It's time to try the original firmware which sounds much cooler :)Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
nILS Posted August 20, 2003 Author Report Share Posted August 20, 2003 Hey, if you say it's working - that's good ;DOk, will try the original firmware and see what it does! Quote Link to comment Share on other sites More sharing options...
nILS Posted August 20, 2003 Author Report Share Posted August 20, 2003 ??? Ok, since the SID played that beautiful song with the test program it appears to work. So, I assume that the problem I have is a software problem. I still only get that clicking sound no matter what I do. I tried playing some notes on channel 1 using JSynth (tried Presets, too), MidiOX and my keyboard - all I hear is "click"... :( Quote Link to comment Share on other sites More sharing options...
TK. Posted August 21, 2003 Report Share Posted August 21, 2003 Which data do you receive on a "Patch request"?F0 00 00 7E 46 00 01 00 F7(use the send/receive function of the MIDIOx SysEx tool)Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
nILS Posted August 21, 2003 Author Report Share Posted August 21, 2003 Hmmmm, I just noticed - my Core doesn't send ANY SysEx at all. Not even with the test_tx program. It used to give me some SysEx with that, and the SID_V2 still works, too! ??? What 's up with that? MidiOx is configured correctly though (tested with my Roland Synth) and the MidiOut on the Core is hooked up correctly, too... Strange. Any idea, TK?/edit: Some add. info Quote Link to comment Share on other sites More sharing options...
TK. Posted August 21, 2003 Report Share Posted August 21, 2003 Does the tx test send other events than SysEx data? -> you've activated the SysEx filter in MIDI-OxDid you check the pinning of the MIDI socket? -> exchanged cablesDid you check the output signals with a LED? http://www.ucapps.de/howtodebug/midi_out_led.gifNOTE: this simple LED circuit helps to indicate the outgoing signal, but it consumes some power - you have to disconnect the LED before connecting the MIDI Out of your MIDIbox with the MIDI In of your PC!Best Regards, Thorsten.

nILS Posted August 21, 2003 Author Report Share Posted August 21, 2003 For some unknown reason the core sends "volume" with the test tx again =) The SID firmware still doesn't give me any results though.I checked the pinning on the midi socket - all correct. Any more ideas?Thanks for your time, TK! Quote Link to comment Share on other sites More sharing options...
TK. Posted August 22, 2003 Report Share Posted August 22, 2003 No, with these inputs (sometimes working, sometimes not) it's impossible to give usefull tips into the right direction. First try to find the root cause why your hardware is so unstable - check the solderings, cables, etc... and use the verify function of IC-Prog to ensure that the firmware has been burned correctly into the PIC.Best Regards, Thorsten.

nILS Posted August 22, 2003 Author Report Share Posted August 22, 2003 I followed your advice and checked everything again - didn't find anything. But since the last time the problem of something not working occured, everything seems fine - except for the Core not working with the SID firmware. The PIC is burnt right, too. So, everything seems to be stable now ;) BUT as I said, the firmware doesn't work. To me it seems the problem could be that the Core is not really getting the MIDI IN right. Is there a test program to check that?Sorry, that I can't give you some more information that would sort some sources of the problem out... :( Quote Link to comment Share on other sites More sharing options...
TK. Posted August 22, 2003 Report Share Posted August 22, 2003 you could use the RxTx test:http://www.ucapps.de/howtodebug/test_rxtx.hex.zipit just forwards incoming events to the MIDI OutBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Guest domas Posted August 22, 2003 Report Share Posted August 22, 2003 Does that FW work wit 18f? Quote Link to comment Share on other sites More sharing options...
TK. Posted August 23, 2003 Report Share Posted August 23, 2003 No, the PIC18F isn't code compatible to the PIC16F...however, the bootloader provides all the functions which are necessary to test the MIDI IO: it sends a SysEx string after power-on (MIDI-Out test) and it reacts on incoming upload requests (MIDI-In test)Best Regards, Thorsten.

nILS Posted August 23, 2003 Author Report Share Posted August 23, 2003 After a lot more testing and checking I'm down to that:The hardware is all ok.The PIC is burnt correctlyThe software on my computer is set up correctlyThe cables are okSID_V2 workstest_tx workstest_rxtx does NOT do anythingthe sid firmware does NOT do what it's supposed to. Clicking sound for every MidiEvent. Sound does NOT come up, when the MidiIn cable is disconnected - MidiIn seems to work. The click is louder when the MidiOut cable is connected. I hope this helps a little. I really don't have any clue what the problem might be... Quote Link to comment Share on other sites More sharing options...
nILS Posted August 23, 2003 Author Report Share Posted August 23, 2003 Since the MidiIn goes directly thru the Optocoupler: How likely is it, that I fried or somehow killed it? Quote Link to comment Share on other sites More sharing options...
TK. Posted August 23, 2003 Report Share Posted August 23, 2003 could you please record the clicking sound? I guess that it doesn't come from the SID, but from your MIDI port, and the reason could be that the optocoupler isn't connected correctly. But I need an audible impression to realize what is going on there.Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Trapstate Posted August 23, 2003 Report Share Posted August 23, 2003 He already did, only in his previous thread. I'll give the link already, if you don't mind nILS ;)http://www.brennsoft.net/temp/shhk.mp3 Quote Link to comment Share on other sites More sharing options...
nILS Posted August 23, 2003 Author Report Share Posted August 23, 2003 I'll try to record it, BUT: The signal is really low, so when I try to record it, I have to turn the volume up so much that all I get is static. I'll try to figure something out. I ordered a new optocoupler just in case. Should be here on Tuesday... Quote Link to comment Share on other sites More sharing options...
TK. Posted August 23, 2003 Report Share Posted August 23, 2003 Alright - this is not the SID, this is digital noise from the MIDI In port - possibly the optocoupler is still ok, the error must be between optocoupler and PIC.Just follow these instructions:http://www.midibox.org/cgi-bin/yabb/YaBB.cgi?board=troubleshooting;action=display;num=1055726526;start=1#1especially check the polarity of the 6N138, the 1N4148 diode and the MIDI cableBest Regards, Thorsten.

nILS Posted August 23, 2003 Author Report Share Posted August 23, 2003 Ok, I will check all that! Here is the audio file: http://www.brennsoft.net/temp/click.mp3Thanks again! Quote Link to comment Share on other sites More sharing options...
nILS Posted August 24, 2003 Author Report Share Posted August 24, 2003 Done with all the testing:I confirmed once more, that all the parts are mounted right. They are.Checks with the LED: LED lights up, but does not dim or flicker, no matter what. (SysEx stream, Midi Events ).When I connect the LED directly to the MidiIn it lights up for every Event. So the signal gets lost somewhere in the Core, I guess?! Optocoupler gone?! Quote Link to comment Share on other sites More sharing options...
nILS Posted August 24, 2003 Author Report Share Posted August 24, 2003 Just saw that: Trapstate: He already did...That was a different sound ;) That was the "sshhh k". I only got that, when I sent patches to the SID via JSynth. Thanks anyways! ;D Quote Link to comment Share on other sites More sharing options...
Trapstate Posted September 3, 2003 Report Share Posted September 3, 2003 Did you already solve it nILS? You connected the led to the output of the optocoupler? In that case it looks like the problem is somewhere near the optocopler, if you're sure everything is connected ok and there's no short I would try replacing the optocoupler.

nILS Posted September 5, 2003 Author Report Share Posted September 5, 2003 No, the problem still occurs. I ordered a new opto coupler, but since I'm moving to another city right now, I don't have the time to test it right away. I think it's the opto coupler, too. We'll see ;) Quote Link to comment Share on other sites More sharing options...
