- rows are now 0..6, cols now 0..D (matching the pics Fredrik posted of
his first flippable PCB)
- either rows or columns can now be the driving pins. the option is in
".../keyboard/.../options.h"
before, if you pressed a key, then shifted layers, then released it, the
first layer's press() would be called, and the 2nd layer's release()
would be called, causing keys to stick, and probably other errors. now,
the layer that the key was on when it was pressed is kept track of, and
the proper release() is called.
also, layers can be shifted per key now, instead of just for the whole
board at once
i also changed how keyboard-private includes are handled. "private"
stuff is now in its own file, instead of being nested in an extra
`#ifdef`.
and i think that's it. i'm pretty tired right now, so there may be
errors, but it seemed to work all right with cursory tests.
- added high-level (logical) led macros, so that the top level firmware
doens't need to know what numbers leds are (or how many there are)
- left low-level (processor specific) led macros in
keyboard/.../teensy-2-0.h , where they were
- put non processor|layout specific led macros in keyboard/.../led.h
- put layout specific led macros into keyboard/.../layout/*.h (with
default empty macro definitions in keyboard/.../layout.h)
also
- cleaned up some typos and such
- moved the debounce time macro to 'keyboard/ergodox.h', since it's
technically keyboard (keyswitch) specific
aggregate changes for PCB update
- documentation updated to reflect that the columns are now the driving
pins, and the columns are the read pins. both are still treated as
open drain.
- macros for led pins 1 and 2 were swapped
- update functions now cycle through columns->low, read rows
- added a matrix macro to map from how we want the key layouts
represented, to how things are scanned into the matrix
also, mcp23018_init() needs fixing: `twi_stop()` needs to be at the end
of transmission blocks. i wouldn't think that would be necessary, but
it seems to be the only thing that'll make it work, and it also seems
consistent with the protocol diagram in the datasheet (lol, imagine
that), so i think that's what i'll have to do. not as though it matters
much i guess, since it's a single master / single slave system anyway, i
was just hoping not to release the bus till i was finished..
- fixed some includes (`uint8_t` comes from a header, not the language)
- put code from some of the .h files into .c files
- now using open drain logic (hi-Z or GND) on both chips instead of
driving the row pins high on the teensy, or using a pull-up resistor
on the row pins with the mcp23018
- put `return 0;` at the end of some functions that weren't void
- fixed/updated some documentation; esp. the row assignments for the
mcp23018
- generalized the unused/row/column pin assignment and init code using
macros, so they'll be much easier to move around if necessary
- fixed a redefinition error in "lib/usb/keyboard-usage-page.h"
