* initial commit * fixup init_rows and read_rows routine * fixup matrix based on Marcus's tracing info * add a temporary keymap * add notes * use a standard tkl ansi keymap * turn on that last column * backslash and backspace row left to fix * reorg from backslash to pgdn * got the matrix done but the backspace location at K4N is still suspect * add reset info into readme * add qmk configurator support * add community layout support * remove uneeded keymap readme * add a new column just for the reset switch * change copyright dates * add cautionary message to readme as we don't know about the lighting condition yet * Update keyboards/duck/orion/v3/v3.c Co-Authored-By: fauxpark <fauxpark@gmail.com> * Update keyboards/duck/orion/v3/v3.c Co-Authored-By: fauxpark <fauxpark@gmail.com> * Update keyboards/duck/orion/v3/v3.c Co-Authored-By: fauxpark <fauxpark@gmail.com> * change bootloader comments
