| uint32_t keyboardGetLEDFlags | ( | ) |
Return the current active LED flags.
Definition at line 333 of file keyboard.c.
| void keyboardInit | ( | struct object * | obj | ) |
Initializes the keyboard.
This function initializes the keyboard controller and requests the keyboard IRQ.
Definition at line 282 of file keyboard.c.
| void keyboardSend | ( | uint8_t | cmd | ) |
Send a command to the keyboard controller.
This function will wait till the keyboard input buffer is empty and then send the command to the controller.
| cmd | The command you want to send |
Definition at line 307 of file keyboard.c.
| void keyboardSetLEDFlags | ( | uint32_t | flags | ) |
Set LED Flags.
Take a look at the keyboard LED flags for more information.
| flags | The flags to set |
Definition at line 322 of file keyboard.c.
| void processScancode | ( | int | extended, |
| uint8_t | scanCode, | ||
| bool | keyUp | ||
| ) |
Handles key presses after the scancode was decoded.
This function translates the scancode into keycode and afterwards to characters depending on the loaded keyboard layout. Moreover it will track the state of modifier keys like capslock or shift.
| extended | Is this a standard or 1 / 2 byte extended scancode? |
| scanCode | The value of the scancode |
| keyUp | Is the key pressed or released? |
Definition at line 100 of file keyboard.c.
| uint8_t extendedKeyCodes[128] |
Maps the multi byte scan codes to an internal keycode
