In `config.h`, we set `ACTUATION_DEPTH_ADJUSTMENT` to `+1`, which puts the actuation point slightly deeper, making the keys less sensitive. + +If [hid_listen](https://www.pjrc.com/teensy/hid_listen.html) is running, `CAPS_LOCK + F9` prints the current RDAC setting and `CAPS_LOCK + F10` prints the default or base setting. `CAPS_LOCK + F11` and `CAPS_LOCK + F12` can be used to adjust the actuation point dynamically. Make only small adjustments and find your ideal setting. For example, if the base setting of your keyboard is 56 but you prefer a slightly lower actuation point at 58, you should set `ACTUATION_DEPTH_ADJUSTMENT` to `+2`. + +If something goes wrong during adjustment, for example keys not actuating anymore or actuating spontaneously, don't panic. Just unplug the keyboard and plug it back in. This will revert all your dynamic changes made with `F11` and `F12`. + +If you discover you have set a too high or low value for `ACTUATION_DEPTH_ADJUSTMENT`, you will need to recompile and reflash your keyboard. diff --git a/keyboards/fc980c/keymaps/actuation-point-example/config.h b/keyboards/fc980c/keymaps/actuation-point-example/config.h new file mode 100644 index 000000000..6c9893f42 --- /dev/null +++ b/keyboards/fc980c/keymaps/actuation-point-example/config.h @@ -0,0 +1,32 @@ +/* Copyright 2017 Balz Guenat + * + * 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.
