Modbus - Piezo Buzzer Bricklet¶

Basic Functions¶

BrickletPiezoBuzzer.beep¶

Function ID:	1
Request:	duration – Type: uint32, Unit: 1 ms, Range: [0 to 232 - 1]
Response:	no response

Beeps for the given duration.

BrickletPiezoBuzzer.morse_code¶

Function ID:	2
Request:	morse – Type: char[60]
Response:	no response

Sets morse code that will be played by the piezo buzzer. The morse code is given as a string consisting of "." (dot), "-" (minus) and " " (space) for dits, dahs and pauses. Every other character is ignored.

For example: If you set the string "...---...", the piezo buzzer will beep nine times with the durations "short short short long long long short short short".

Advanced Functions¶

BrickletPiezoBuzzer.get_identity¶

Function ID:	255
Request:	empty payload
Response:	uid – Type: char[8] connected_uid – Type: char[8] position – Type: char, Range: ['a' to 'h', 'z'] hardware_version – Type: uint8[3] 0: major – Type: uint8, Range: [0 to 255] 1: minor – Type: uint8, Range: [0 to 255] 2: revision – Type: uint8, Range: [0 to 255] firmware_version – Type: uint8[3] 0: major – Type: uint8, Range: [0 to 255] 1: minor – Type: uint8, Range: [0 to 255] 2: revision – Type: uint8, Range: [0 to 255] device_identifier – Type: uint16, Range: [0 to 216 - 1]

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here. 

Callbacks¶

BrickletPiezoBuzzer.CALLBACK_BEEP_FINISHED¶

Function ID:	3
Response:	empty payload

This callback is triggered if a beep set by beep is finished

BrickletPiezoBuzzer.CALLBACK_MORSE_CODE_FINISHED¶

Function ID:	4
Response:	empty payload

This callback is triggered if the playback of the morse code set by morse_code is finished.
