Public Instance Methods

get_identity() click to toggle source

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 :ref:`Isolator Bricklet <isolator_bricklet>` is always at position 'z'.

The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|

  send_request FUNCTION_GET_IDENTITY, [], '', 33, 'Z8 Z8 k C3 C3 S'
end
get_mode() click to toggle source

Returns the mode as set by BrickletAnalogOut#set_mode.

def get_mode
  check_validity

  send_request FUNCTION_GET_MODE, [], '', 9, 'C'
end
get_voltage() click to toggle source

Returns the voltage as set by BrickletAnalogOut#set_voltage.

# File lib/tinkerforge/bricklet_analog_out.rb, line 56
def get_voltage
  check_validity

  send_request FUNCTION_GET_VOLTAGE, [], '', 10, 'S'
end
set_mode(mode) click to toggle source

Sets the mode of the analog value. Possible modes:

  • 0: Normal Mode (Analog value as set by BrickletAnalogOut#set_voltage is applied)

  • 1: 1k Ohm resistor to ground

  • 2: 100k Ohm resistor to ground

  • 3: 500k Ohm resistor to ground

Setting the mode to 0 will result in an output voltage of 0 V. You can jump to a higher output voltage directly by calling BrickletAnalogOut#set_voltage.

# File lib/tinkerforge/bricklet_analog_out.rb, line 71
def set_mode(mode)
  check_validity

  send_request FUNCTION_SET_MODE, [mode], 'C', 8, ''
end
set_voltage(voltage) click to toggle source

Sets the voltage. Calling this function will set the mode to 0 (see BrickletAnalogOut#set_mode).

# File lib/tinkerforge/bricklet_analog_out.rb, line 49
def set_voltage(voltage)
  check_validity

  send_request FUNCTION_SET_VOLTAGE, [voltage], 'S', 8, ''
