Stigmata Posted January 20, 2009 Report Share Posted January 20, 2009 Hi there!Been away for long time now...And I decide to rebuild my Sid v1.7303 to the new v2.And keep my old core V2, just for now...(I got the Pcb from Wilba but i haven´t got the time to rebuild my sid)And I have some questions, (it´s like start all over again).When I look at the new core V3 the PWM on J10 is connected to Pin #17 of PIC, do I need that?And when I look att my other core V2 (slave) I didn´t connect SC on J4 to Pin #28, why??? :o I think I left that for a reason....HmmmOn the slave cores do i need the R12 1k on J4?And another thing...on my master core i didn´t wire the J7:SO/PIC to the SID CLK pin.The SID running on the 1 MHz oscillator instead..Can I keep it like that?I just want do do this the easy way.... ;) Haven´t got so much time with 2 small children.....Like I said, been away for a loooong time..ThanksChristoffer Quote Link to comment Share on other sites More sharing options...
toneburst Posted January 20, 2009 Report Share Posted January 20, 2009 Welcome back. I'm in a similar position- been away a long time. Now I'm working on one of Wilba's MB-6582s, which is massively more ambitious than what I was working on before. And I seem doomed to make all the mistakes I made the first time, all over again (just trashed another LCD) :(I'm sure you'll do better than me though :)a|x Quote Link to comment Share on other sites More sharing options...
TK. Posted January 20, 2009 Report Share Posted January 20, 2009 Welcome back, Christoffer! :)Your questions are answered in detail here:http://www.ucapps.de/midibox_sid_manual_up.htmland here:http://www.ucapps.de/mbhp_sid_old.htmlThese are mainly quality improvementsWhen I look at the new core V3 the PWM on J10 is connected to Pin #17 of PIC, do I need that?...And another thing...on my master core i didn´t wire the J7:SO/PIC to the SID CLK pin.The SID running on the 1 MHz oscillator instead..Can I keep it like that?It's better to remove the oscillator, and to clock the SID module from the core. How you are doing this (via CORE:J10 or with a directly connected cable) doesn't matter.Without this modification, drum sounds could be triggered twiceOn the slave cores do i need the R12 1k on J4?no (only required if MBHP_IIC_MIDI or similar IIC devices which require clock stretching are connected)Best Regards, Thorsten.

Stigmata Posted January 24, 2009 Author Report Share Posted January 24, 2009 Done!!Works great! Thanks!Next thing is to remake the matrix, the old one working bad..The button i used for that is taken from and old code/cardreader lock...Christoffer Quote Link to comment Share on other sites More sharing options...
