Member Function Documentation
int _putc | ( | int | c ) | [virtual] |
Send a character.
- Parameters:
-
c character to be sent
- Returns:
- true if there is no error, false otherwise
Definition at line 449 of file USBKeyboard.cpp.
bool keyCode | ( | uint8_t | key, |
uint8_t | modifier = 0 |
||
) |
To send a character defined by a modifier(CTRL, SHIFT, ALT) and the key.
//To send CTRL + s (save) keyboard.keyCode('s', KEY_CTRL);
- Parameters:
-
modifier bit 0: KEY_CTRL, bit 1: KEY_SHIFT, bit 2: KEY_ALT (default: 0) key character to send
- Returns:
- true if there is no error, false otherwise
Definition at line 453 of file USBKeyboard.cpp.
uint8_t lockStatus | ( | ) |
Read status of lock keys.
Useful to switch-on/off leds according to key pressed. Only the first three bits of the result is important:
- First bit: NUM_LOCK
- Second bit: CAPS_LOCK
- Third bit: SCROLL_LOCK
- Returns:
- status of lock keys
Definition at line 445 of file USBKeyboard.cpp.
bool mediaControl | ( | MEDIA_KEY | key ) |
Control media keys.
- Parameters:
-
key media key pressed (KEY_NEXT_TRACK, KEY_PREVIOUS_TRACK, KEY_STOP, KEY_PLAY_PAUSE, KEY_MUTE, KEY_VOLUME_UP, KEY_VOLUME_DOWN)
- Returns:
- true if there is no error, false otherwise
Definition at line 485 of file USBKeyboard.cpp.
bool read | ( | HID_REPORT * | report ) | [inherited] |

report Report which will be sent (a report is defined by all data and the length)
- Returns:
- true if successful
Definition at line 34 of file USBHID.cpp.
bool sendNB | ( | HID_REPORT * | report ) | [inherited] |
Send a Report.
warning: non blocking

uint32_t | size, | ||
uint32_t | maxSize, | ||
int | timeout_ms | ||
) | [inherited] |
Write a certain endpoint.
Blocks until the report has been sent successfully, or until the timeout expires, whichever comes first.
- Parameters:
-
endpoint endpoint to write buffer data contained in buffer will be write size the number of bytes to write maxSize the maximum length that can be written on this endpoint timeout_ms timeout in milliseconds
- Returns:
- true if successful, false on error or timeout
