For the `x` coordinate, the value `0` is the leftmost position, whereas the value `1` is the rightmost position. +For the `y` coordinate, `0` is at the top and `1` at the bottom. + +Here is an example setting the cursor in the middle of the screen: + +```c +digitizer_t digitizer; +digitizer.x = 0.5; +digitizer.y = 0.5; +digitizer.tipswitch = 0; +digitizer.inrange = 1; +digitizer_set_report(digitizer); +``` + +The `tipswitch` member triggers what equates to a click when set to `1`. The `inrange` member is required for the change in coordinates to be taken. It can then be set to `0` in a new report to signal the end of the digitizer interaction, but it is not strictly required. + +Once all members are set to the desired value, the `status` member needs its bitmask `DZ_UPDATED` to be set so the report is sent during the next main loop iteration. diff --git a/keyboards/handwired/onekey/keymaps/digitizer/keymap.c b/keyboards/handwired/onekey/keymaps/digitizer/keymap.c new file mode 100644 index 0000000000..6b304e86fe --- /dev/null +++ b/keyboards/handwired/onekey/keymaps/digitizer/keymap.c @@ -0,0 +1,38 @@ + /* Copyright 2021 QMK + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation, either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
