LenweTasasartir Posted March 24, 2008 Report Share Posted March 24, 2008 Hi guys!I've changed MIDI interface to working one, and I'm possible continue creating my MB-SID.Let's begin from LCD:When I power everything on, black bar appears on LCD and after some time it goes blank or... It displays something what's on the photos.Datasheet: http://sklep.avt.pl/photo/_pdf/BTHQ_22005VSS.pdfAnd SID:I've napierzaza Double SID module with 2x8580's. Testtone runs well, sounds clear, has 1kHz. But if I change app to sid synt, and play something on keyboard it sounds strange. In sounds.mp3 I've attached recording which contains 6 ocataves played from low to high.Have anybody has any idea?sounds.mp3DSCN4154.JPGDSCN4155.JPGDSCN4156.JPGsounds.mp3 Quote Link to comment Share on other sites More sharing options...
TK. Posted March 25, 2008 Report Share Posted March 25, 2008 Both is strange.LCD: you considered the 4bit interface (D0-D3 should not be connected)?LCD interconnection test done?Strange Sound: it's interesting that the waveform and volume (or ADSR setting?) changes while you are playing different notes. It could either be a powering problem, connection problem or firmware upload problem - hard to diagnose via remote, but let's start with the power problem: does it also sound so strange when the LCD (and especially the backlight) is *not* connected?Best Regards, Thorsten,.

LenweTasasartir Posted March 26, 2008 Author Report Share Posted March 26, 2008 Ok, LCD problem solved. E pin was partly disconnected in some way.On LCD interconnection test, after going out from E line test, LCD goes blank.After fixing second SID audio channel, I was going to check how this one sounds.Checked testtone - clear.If done SID interconnection test, i've lower volatages on A3 and A4 (3,5V, but I've uncalibrated multimeter...) , +5 at rest.Unfortunately when I'm trying to start MIDIboxSID app, it restarts on "Launching CS".Thanks for help ;)EDIT:Same without SIDs board.DSCN4166.JPG Quote Link to comment Share on other sites More sharing options...
