### (2012-04-11)
|
|
|
|
|
As of now, it looks like we have a working 6-KRO keyboard firmware for a Teensy
|
|
|
|
|
2.0 with a MCP23018 I/O expander. It's scanning at ~167 Hz, most of which is
|
|
|
|
|
spent communicating over I²C. This should be fast enough, I think.
|
|
|
|
|
Slight improvements might be possible (without finding a microprocessor capable
|
|
|
|
|
of > 400 kHz I²C or using SPI, that is, which I imagine would speed things
|
|
|
|
|
up a lot - but it'd also be much less convenient). I'll attempt them if I see
|
|
|
|
|
the need.
|
|
|
|
|
|
|
|
|
|
Also, layers are implemented, but untested, as no keymaps are written to use
|
|
|
|
|
them yet. Implementing on-keyboard hardware remapping seems like it'd be very
|
|
|
|
|
possible too, but I'd need to try it (and learn how to programmatically store
|
|
|
|
|
stuff in program space) to see if it'd work; and I'm not sure of a good way to
|
|
|
|
|
do the interface, since different people will likely have different keycap
|
|
|
|
|
layouts on the ergoDOX.
|
|
|
|
|
|
|
|
|
|
Getting to N-KRO is a goal, but I honestly have no idea whether it'll be
|
|
|
|
|
accomplished. Ideally, I'd like a variable-KRO, where the keyboard is 6-KRO
|
|
|
|
|
till you press the 7th key (so if you're worried about compatibility, just
|
|
|
|
|
don't press more than 6 keys at a time). From what I've read, it might be
|
|
|
|
|
possible, but I just finished everything else (so I'm slightly tired), and the
|
|
|
|
|
USB spec is scary.
|
|
|
|
|
|
|
|
|
|
Discussions about the project as a whole are going on at the forum page (linked
|
|
|
|
|
in the title) so if you have any imput (or want to participate in the group
|
|
|
|
|
buy!), please stop by. :) .
