It contains All projects need to have a `config.h` file that sets things like the matrix size, product name, USB VID/PID, description and other settings. In general, use this file to set essential information and defaults for your keyboard that will always work. +The `config.h` files can also be placed in sub-folders, and the order in which they are read is as follows: + +* `keyboards/top_folder/config.h` + * `keyboards/top_folder/sub_1/config.h` + * `keyboards/top_folder/sub_1/sub_2/config.h` + * `keyboards/top_folder/sub_1/sub_2/sub_3/config.h` + * `keyboards/top_folder/sub_1/sub_2/sub_3/sub_4/config.h` + * `users/a_user_folder/config.h` + * `keyboards/top_folder/keymaps/a_keymap/config.h` + * `keyboards/top_folder/sub_1/sub_2/sub_3/sub_4/post_config.h` + * `keyboards/top_folder/sub_1/sub_2/sub_3/post_config.h` + * `keyboards/top_folder/sub_1/sub_2/post_config.h` + * `keyboards/top_folder/sub_1/post_config.h` +* `keyboards/top_folder/post_config.h` + +The `post_config.h` file can be used for additional post-processing, depending on what is specified in the `config.h` file. For example, if you define the `IOS_DEVICE_ENABLE` macro in your keymap-level `config.h` file as follows, you can configure more detailed settings accordingly in the `post_config.h` file: + +* `keyboards/top_folder/keymaps/a_keymap/config.h` + ```c + #define IOS_DEVICE_ENABLE + ``` +* `keyboards/top_folder/post_config.h` + ```c + #ifndef IOS_DEVICE_ENABLE + // USB_MAX_POWER_CONSUMPTION value for this keyboard + #define USB_MAX_POWER_CONSUMPTION 400 + #else + // fix iPhone and iPad power adapter issue + // iOS device need lessthan 100 + #define USB_MAX_POWER_CONSUMPTION 100 + #endif + + #ifdef RGBLIGHT_ENABLE + #ifndef IOS_DEVICE_ENABLE + #define RGBLIGHT_LIMIT_VAL 200 + #define RGBLIGHT_VAL_STEP 17 + #else + #define RGBLIGHT_LIMIT_VAL 35 + #define RGBLIGHT_VAL_STEP 4 + #endif + #ifndef RGBLIGHT_HUE_STEP + #define RGBLIGHT_HUE_STEP 10 + #endif + #ifndef RGBLIGHT_SAT_STEP + #define RGBLIGHT_SAT_STEP 17 + #endif + #endif + ``` + +?> If you define options using `post_config.h` as in the above example, you should not define the same options in the keyboard- or user-level `config.h`. + ### `rules.mk` The presence of this file means that the folder is a keyboard target and can be used in `make` commands. This is where you setup the build environment for your keyboard and configure the default set of features.
