This firmware converts PS/2 keyboard protocol to USB.(It supports Scan Code Set 2.)
PD1
and Data on PD0
.(Recommended. Soarer’s converter compatible)PD1
and Data on PD0
.PD5
and Data on PD2
.To change pin configuration edit config.h and Makefile.
For TMK converter Rev.2:
$ make -f Makefile.rev2 clean
$ make -f Makefile.rev2 KEYMAP=plain
To program firmware push the button on converter and run:
$ make -f Makefile.rev2 KEYMAP=plain dfu
make -f Makefile.rev1
instead.jis
, spacefn
or your own in place of plain
.Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named keymap_<name>.c
and see keymap document(you can find in README.md of top directory) and existent keymap files.
Following three methods can be used to implement PS/2 signal handling.
This is expected to implemented with portable C code for reference.
Uses pin interrupt to detect falling edge of clock line.
Uses AVR USART engine to receive PS/2 signal.
To select method edit Makefile.
With V-USB you can use this converter on ATmega(168/328) but it doesn’t support NKRO at this time.
