By setting `RGB_MATRIX_CUSTOM_USER` (and/or `RGB_MATRIX_CUSTOM_KB`) in `rules.mk`, new effects can be defined directly from userspace, without having to edit any QMK core files.
By setting `RGB_MATRIX_CUSTOM_USER = yes` in `rules.mk`, new effects can be defined directly from your keymap or userspace, without having to edit any QMK core files.
To declare new effects, create a new `rgb_matrix_user/kb.inc` that looks something like this:
To declare new effects, create a `rgb_matrix_user.inc` file in the user keymap directory or userspace folder.
`rgb_matrix_user.inc` should go in the root of the keymap directory.
`rgb_matrix_kb.inc` should go in the root of the keyboard directory.
?> Hardware maintainers who want to limit custom effects to a specific keyboard can create a `rgb_matrix_kb.inc` file in the root of the keyboard directory, and add `RGB_MATRIX_CUSTOM_KB = yes` to the keyboard level `rules.mk`.
To use custom effects in your code, simply prepend `RGB_MATRIX_CUSTOM_` to the effect name specified in `RGB_MATRIX_EFFECT()`. For example, an effect declared as `RGB_MATRIX_EFFECT(my_cool_effect)` would be referenced with:
