Field Documentation

◆ cond

kbd_cond_t kbd_state_t::cond

The latest raw condition of the keyboard.

◆ kbd_repeat_key

uint8 kbd_state_t::kbd_repeat_key

Key that is repeating.

◆ kbd_repeat_timer

uint64 kbd_state_t::kbd_repeat_timer

Time that the next repeat will trigger.

◆ key_queue

uint32 kbd_state_t::key_queue[KBD_QUEUE_SIZE]

Individual keyboard queue.

You should not access this variable directly. Please use the appropriate function to access it.

◆ matrix

uint8 kbd_state_t::matrix[MAX_KBD_KEYS]

Key array.

This array lists the state of all possible keys on the keyboard. It can be used for key repeat and debouncing. This will be non-zero if the key is currently being pressed.
