Detailed Description

Keyboard matrix internal APIs.

Field Documentation

drive_column

void(* input_kbd_matrix_api::drive_column) (const struct device *dev, int col)

Request to drive a specific column.

Request to drive a specific matrix column, or none, or all.

Parameters

dev	Pointer to the keyboard matrix device.
col	The column to drive, or INPUT_KBD_MATRIX_COLUMN_DRIVE_NONE or INPUT_KBD_MATRIX_COLUMN_DRIVE_ALL.

read_row

kbd_row_t(* input_kbd_matrix_api::read_row) (const struct device *dev)

Read the matrix row.

Parameters

dev	Pointer to the keyboard matrix device.

set_detect_mode

void(* input_kbd_matrix_api::set_detect_mode) (const struct device *dev, bool enabled)

Request to put the matrix in detection mode.

Request to put the driver in detection mode, this is called after a request to drive all the column and typically involves reenabling interrupts row pin changes.

Parameters

dev	Pointer to the keyboard matrix device.
enable	Whether detection mode has to be enabled or disabled.
