This keycode, and the necessary modifiers (`trigger_mods`) must be pressed to activate this override. Set this to the keycode of the key that should activate the override. Set to `KC_NO` to require only the necessary modifiers to be pressed and no non-modifier. | +| `uint8_t trigger_mods` | Which mods need to be down for activation. If both sides of a modifier are set (e.g. left ctrl and right ctrl) then only one is required to be pressed (e.g. left ctrl suffices). Use the `MOD_MASK_XXX` and `MOD_BIT()` macros for this. | +| `layer_state_t layers` | This is a BITMASK (!), defining which layers this override applies to. To use this override on layer i set the ith bit `(1 << i)`. | +| `uint8_t negative_mod_mask` | Which modifiers cannot be down. It must hold that `(active_modifiers & negative_mod_mask) == 0`, otherwise the key override will not be activated. An active override will be deactivated once this is no longer true. | +| `uint8_t suppressed_mods` | Modifiers to 'suppress' while the override is active. To suppress a modifier means that even though the modifier key is held down, the host OS sees the modifier as not pressed. Can be used to suppress the trigger modifiers, as a trivial example. | +| `uint16_t replacement` | The complex keycode to send as replacement when this override is triggered. This can be a simple keycode, a key-modifier combination (e.g. `C(KC_A)`), or `KC_NO` (to register no replacement keycode). Use in combination with suppressed_mods to get the correct modifiers to be sent. | +| `ko_option_t options` | Options controlling the behavior of the override, such as what actions are allowed to activate the override. | +| `bool (*custom_action)(bool activated, void *context)` | If not NULL, this function will be called right before the replacement key is registered, along with the provided context and a flag indicating whether the override was activated or deactivated. This function allows you to run some custom actions for specific key overrides. If you return `false`, the replacement key is not registered/unregistered as it would normally. Return `true` to register and unregister the override normally. | +| `void *context` | A context that will be passed to the custom action function. | +| `bool *enabled` | If this points to false this override will not be used. Set to NULL to always have this override enabled. | + +### Reference for `ko_option_t` + +Bitfield with various options controlling the behavior of a key override. + +| Value | Description | +|------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| `ko_option_activation_trigger_down` | Allow activating when the trigger key is pressed down. | +| `ko_option_activation_required_mod_down` | Allow activating when a necessary modifier is pressed down. | +| `ko_option_activation_negative_mod_up` | Allow activating when a negative modifier is released. | +| `ko_option_one_mod` | If set, any of the modifiers in `trigger_mods` will be enough to activate the override (logical OR of modifiers). If not set, all the modifiers in `trigger_mods` have to be pressed (logical AND of modifiers). | +| `ko_option_no_unregister_on_other_key_down` | If set, the override will not deactivate when another key is pressed down.

Understanding this is essential to be able to take full advantage of all the options offered by key overrides. + +#### Activation + +When the necessary keys are pressed (`trigger_mods` + `trigger`), the override is 'activated' and the replacement key is registered in the keyboard report (`replacement`), while the `trigger` key is removed from the keyboard report. The trigger modifiers may also be removed from the keyboard report upon activation of an override (`suppressed_mods`). The override will not activate if any of the `negative_modifiers` are pressed. + +Overrides can activate in three different cases: + +1. The trigger key is pressed down and necessary modifiers are already down. +2. A necessary modifier is pressed down, while the trigger key and other necessary modifiers are already down. +3. A negative modifier is released, while all necessary modifiers and the trigger key are already down. + +Use the `option` member to customize which of these events are allowed to activate your overrides (default: all three). + +In any case, a key override can only activate if the `trigger` key is the _last_ non-modifier key that was pressed down. This emulates the behavior of how standard OSes (macOS, Windows, Linux) handle normal key input (to understand: Hold down `a`, then also hold down `b`, then hold down `shift`; `B` will be typed but not `A`). + +#### Deactivation + +An override is 'deactivated' when one of the trigger keys (`trigger_mods`, `trigger`) is lifted, another non-modifier key is pressed down, or one of the `negative_modifiers` is pressed down. When an override deactivates, the `replacement` key is removed from the keyboard report, while the `suppressed_mods` that are still held down are re-added to the keyboard report. By default, the `trigger` key is re-added to the keyboard report if it is still held down and no other non-modifier key has been pressed since. This again emulates the behavior of how standard OSes handle normal key input (To understand: hold down `a`, then also hold down `b`, then also `shift`, then release `b`; `A` will not be typed even though you are holding the `a` and `shift` keys). Use the `option` field `ko_option_no_reregister_trigger` to prevent re-registering the trigger key in all cases. + +#### Key Repeat Delay + +A third way in which standard OS-handling of modifier-key input is emulated in key overrides is with a ['key repeat delay'](https://www.dummies.com/computers/pcs/set-your-keyboards-repeat-delay-and-repeat-rate/). To explain what this is, let's look at how normal keyboard input is handled by mainstream OSes again: If you hold down `a`, followed by `shift`, you will see the letter `a` is first typed, then for a short moment nothing is typed and then repeating `A`s are typed. Take note that, although shift is pressed down just after `a` is pressed, it takes a moment until `A` is typed. This is caused by the aforementioned key repeat delay, and it is a feature that prevents unwanted repeated characters from being typed. + +This applies equally to releasing a modifier: When you hold `shift`, then press `a`, the letter `A` is typed. Now if you release `shift` first, followed by `a` shortly after, you will not see the letter `a` being typed, even though for a short moment of time you were just holding down the key `a`. This is because no modified characters are typed until the key repeat delay has passed. + + This exact behavior is implemented in key overrides as well: If a key override for `shift` + `a` = `b` exists, and `a` is pressed and held, followed by `shift`, you will not immediately see the letter `b` being typed. Instead, this event is deferred for a short moment, until the key repeat delay has passed, measured from the moment when the trigger key (`a`) was pressed down. + +The duration of the key repeat delay is controlled with the `KEY_OVERRIDE_REPEAT_DELAY` macro. Define this value in your `config.h` file to change it. It is 500ms by default. + + +## Difference to Combos + +Note that key overrides are very different from [combos](https://docs.qmk.fm/#/feature_combo). Combos require that you press down several keys almost _at the same time_ and can work with any combination of non-modifier keys. Key overrides work like keyboard shortcuts (e.g. `ctrl` + `z`): They take combinations of _multiple_ modifiers and _one_ non-modifier key to then perform some custom action. Key overrides are implemented with much care to behave just like normal keyboard shortcuts would in regards to the order of pressed keys, timing, and interacton with other pressed keys. There are a number of optional settings that can be used to really fine-tune the behavior of each key override as well. Using key overrides also does not delay key input for regular key presses, which inherently happens in combos and may be undesirable. diff --git a/docs/feature_oled_driver.md b/docs/feature_oled_driver.md index f3b659b1bc..c90aabb9c6 100644 --- a/docs/feature_oled_driver.md +++ b/docs/feature_oled_driver.md @@ -346,6 +346,10 @@ bool oled_scroll_left(void); // Returns true if the screen was not scrolling or stops scrolling bool oled_scroll_off(void); +// Inverts the display +// Returns true if the screen was or is inverted +bool oled_invert(bool invert); + // Returns the maximum number of characters that will fit on a line uint8_t oled_max_chars(void); diff --git a/docs/feature_rgb_matrix.md b/docs/feature_rgb_matrix.md index 08d5c9c4c6..f3e25f2f13 100644 --- a/docs/feature_rgb_matrix.md +++ b/docs/feature_rgb_matrix.md @@ -145,9 +145,22 @@ There is basic support for addressable RGB matrix lighting with the I2C IS31FL37 RGB_MATRIX_ENABLE = yes RGB_MATRIX_DRIVER = IS31FL3737 ``` +You can use between 1 and 2 IS31FL3737 IC's.

This is modelled on a remote procedure call, with the master invoking a function on the slave side, with the ability to send data from master to slave, process it slave side, and send data back from slave to master. + +To leverage this, a keyboard or user/keymap can define a comma-separated list of _transaction IDs_: + +```c +// for keyboard-level data sync: +#define SPLIT_TRANSACTION_IDS_KB KEYBOARD_SYNC_A, KEYBOARD_SYNC_B +// or, for user: +#define SPLIT_TRANSACTION_IDS_USER USER_SYNC_A, USER_SYNC_B, USER_SYNC_C +``` + +These _transaction IDs_ then need a slave-side handler function to be registered with the split transport, for example: + +```c +typedef struct _master_to_slave_t { + int m2s_data; +} master_to_slave_t; + +typedef struct _slave_to_master_t { + int s2m_data; +} slave_to_master_t; + +void user_sync_a_slave_handler(uint8_t in_buflen, const void* in_data, uint8_t out_buflen, void* out_data) { + const master_to_slave_t *m2s = (const master_to_slave_t*)in_data; + slave_to_master_t *s2m = (slave_to_master_t*)out_data; + s2m->s2m_data = m2s->m2s_data + 5; // whatever comes in, add 5 so it can be sent back +} + +void keyboard_post_init_user(void) { + transaction_register_rpc(USER_SYNC_A, user_sync_a_slave_handler); +} +``` + +The master side can then invoke the slave-side handler - for normal keyboard functionality to be minimally affected, any keyboard- or user-level code attempting to sync data should be throttled: + +```c +void housekeeping_task_user(void) { + if (is_keyboard_master()) { + // Interact with slave every 500ms + static uint32_t last_sync = 0; + if (timer_elapsed32(last_sync) > 500) { + master_to_slave_t m2s = {6}; + slave_to_master_t s2m = {0}; + if(transaction_rpc_exec(USER_SYNC_A, sizeof(m2s), &m2s, sizeof(s2m), &s2m)) { + last_sync = timer_read32(); + dprintf("Slave value: %d\n", s2m.s2m_data); // this will now be 11, as the slave adds 5 + } else { + dprint("Slave sync failed!\n"); + } + } + } +} +``` + +!> It is recommended that any data sync between halves happens during the master side's _housekeeping task_.
