That sounds like a great idea.
How about a real open source USB pic programmer (USB2 would be even
better?). If done well it could even be made MPLAB compatable (I
currently use the Warp13, serial version which is great, but serial)
because soon enough Microchip will release a Linux port (or someone will
get it running properly with WINE). The problem is, if it's worth
doing, it's worth doing well, so it should support pretty much all
devices and maybe even eeprom. Schematics, software and firmware for
the onboard microcontroller/s should be available for free, with kits
and prebuilt units available in the US, EU and Australia for a
reasonable price.
Just my $0.02, not that I have any right to comment as I don't have the
skills to be able to contribute :(
I hope something good comes of this, it would be really nice to see.
Justin.
