@gillspice
Yeah i used 100mhz
jackgassett
@jackgassett
perfect
it was probably the DAC that needed the higher clock.
I don't know much about the filter so maybe it did too.
gillspice
@gillspice
The filters need at least 12mhz
jackgassett
@jackgassett
ah, ok good.

I was thinking about your little papillio board, it would be cool to have a carrier board where you could plug a bunch of those in. Wouldnt be one chip to rule them all, but at least one board
jackgassett
@jackgassett
So I was thinking more about the next papilio boards.
I've actually been testing the Papilio Flex board over the last couple days and things look promising so far.
What I've been thinking is this:
take just the Spartan 6 and leave the mini pci express connector for memory to be added.
but don't break it out to a DIP form yet.
instead break it out to a mini pci express edge connections
so it essentially becomes a mini pci express board that can have another PCIe card stacked on top of it for memory expansion.
Then make breakout boards in various form factors for it.
One for GadgetBox, one for Papilio One form, one for Arduino form factor
and finally, I can make a DIP form factor, and it would actually be possible to make a DIP form factor that fits the SID chip socket.
so you buy the Papilio core seperately
and you can put that core into various motherboards.

@gillspice
I like it
jackgassett
@jackgassett
one logistics problem I have is that it is making me go broke trying to stock all the different Papilio boards.
It would be better to have one core module and have most of my inventory money tied up in that.
and then make lower cost motherboards.
gillspice
@gillspice
Seeed doesnt handle inventory for you?
jackgassett
@jackgassett
they buy some when I ask them to manufacture 100
but I have to buy 100 at a time
it recently changed with them going public and has caused a big headache for me.

@ jackgassett I am working on an interface board between the Midibox and Papilio Pro. It started out pretty simple with just a couple level shifters, but I figured it might as well share the outline of the papilio and with all that real estate I decided to add the audio output filters to it with a buffer and 2 of the PICs midibox currently uses to control the SIDs. My thought is that if the goal of using the STM32 to control them materializes the pics could just be depopped. The board is here: https://tools.upverter.com/eda/#designId=32fbede244e1a406

@jackgassett
Hey, it looks nice. :)
first time I've seen upverter in forever too. Looks like it has come a long way.

@gillspice
Working ln programming kne of the pics now

@gillspice
Just got all 4 SIDs in the papilio going being driven by the midibox through the board I milled.
gillspice
@gillspice
@jackgassett I want to get my designlab files for the midibox quad SID into github somewhere now that I have it working, where is a good place for it and what files do I need?
jackgassett
@jackgassett
hey
you should be able to use the archive option
tools/archive sketch
and it will put everything into a zip file for you
or if you want to add it to github...
just do the sketch directory.
gillspice
@gillspice
I had to modify the sid hdl though, just to change the clock source for the parallel interface
jackgassett
@jackgassett
ok, I think then you probably need to make a copy of the sid hdl
and rename it to something a little different
like parallel at the end.
and then include those files, the hdl and symbol files to your sketch directory.

@jackgassett just wanted to let you know I'm still working on the concept we discussed of eurorack modules to control chips, either FPGA implementations or real, I'm thinking of taking visual cues from the original device and using them for the modules. For example, use the C64 color scheme for SID control modules, NES color scheme for 2A03 modules, etc
starting with SID since there is the biggest head start there
Want to do SID, Atari POKEY, Atari TIA, OPL3 (Adlib/Soundblaster), Sega Genesis, NES
the FM stuff would make more sense to use real chips since NOS is available and not too expensive (and would be resource intensive to do in FPGA
the rest could be FPGA or real or a mix

I'm looking into some oddities with the MIDI controller. Doesn't seem to like to behave when on a bus with other devices and locks up, which is described by another forum member.
