Welcome to pyFirmata’s documentation!¶
Contents:
pyFirmata¶
- class pyfirmata.pyfirmata.Board(port, layout, baudrate=57600, name=None)¶
Base class for any board
- add_cmd_handler(cmd, func)¶
Adds a command handler for a command.
- exit()¶
Call this to exit cleanly.
- get_firmata_version()¶
Returns a version tuple (major, mino) for the firmata firmware on the board.
- get_pin(pin_def)¶
Returns the activated pin given by the pin definition. May raise an InvalidPinDefError or a PinAlreadyTakenError.
Parameters: pin_def – Pin definition as described in TODO, but without the arduino name. So for example a:1:i.
- iterate()¶
Reads and handles data from the microcontroller over the serial port. This method should be called in a main loop, or in an Iterator instance to keep this boards pin values up to date
- pass_time(t)¶
Non-blocking time-out for t seconds.
- send_sysex(sysex_cmd, data=[])¶
Sends a SysEx msg.
Parameters: - sysex_cmd – A sysex command byte
- data – A list of 7-bit bytes of arbitrary data (bytes may be already converted to chr’s)
- servo_config(pin, min_pulse=544, max_pulse=2400, angle=0)¶
Configure a pin as servo with min_pulse, max_pulse and first angle. min_pulse and max_pulse default to the arduino defaults.
- setup_layout(board_layout)¶
Setup the Pin instances based on the given board-layout. Maybe it will be possible to do this automatically in the future, by polling the board for its type.
- class pyfirmata.pyfirmata.Pin(board, pin_number, type=2, port=None)¶
A Pin representation
- disable_reporting()¶
Disable the reporting of an input pin
- enable_reporting()¶
Set an input pin to report values
- mode¶
Mode of operation for the pin. Can be one of the pin modes: INPUT, OUTPUT, ANALOG, PWM or SERVO (or UNAVAILABLE)
- read()¶
Returns the output value of the pin. This value is updated by the boards Board.iterate() method. Value is alway in the range 0.0 - 1.0
- write(value)¶
Output a voltage from the pin
Parameters: value – Uses value as a boolean if the pin is in output mode, or expects a float from 0 to 1 if the pin is in PWM mode. If the pin is in SERVO the value should be in degrees.
