Hello FC community, In the spirit of better late than never, I just wrote and published a proper user's manual for our DUART28 adapter:
https://www.freecalypso.org/pub/GSM/FreeCalypso/duart28-userman-latest.pdf https://www.freecalypso.org/pub/GSM/FreeCalypso/duart28-userman-latest.ps (PostScript is what my troff toolchain produces natively, whereas PDF - the format preferred by those who didn't grow up in the Golden Era of PostScript - is produced with ps2pdf tool which is a black box to me; I always publish both.) Those of you who have DUART28 adapters with your FCDEV3B or Caramel2 kits, now you can read the full details. :) If you feel that some info is missing from this user's manual and needs to be added, please post in this thread. No graphical schematics exist for this board (none were ever drawn - like most of my boards, the design was done in a text-based PCB HDL instead), but the design files that do exist are published: https://www.freecalypso.org/pub/GSM/FreeCalypso/duart28-design-r1.tar.bz2 The linked tarball includes non-graphical "schematic" source for the board, as well as PCB layout (done by Majenko, one of several hired contractors I have worked with over the years) in pcb-rnd and Gerber formats. Hasta la Victoria, Siempre, Mychaela aka The Mother _______________________________________________ Community mailing list Community@freecalypso.org https://www.freecalypso.org/mailman/listinfo/community
