                ADC

ADC class is used to access analog inputs usually driven by sensors.

Instance Methods

__init__(self, agent)
Constructs an ADC object.

int

read_pin_raw(self, pin)
Reads and returns the value on the specified analog input pin.

list of ints

read_raw(self)
Reads and returns the value (0 - 0xFFFF) on all analog input pins.

list of floats

read(self)
Reads and returns the value (0 - Vref) on all analog input pins.

float

read_pin(self, pin)
Reads and returns the value on the specified analog input pin.

Inherited from Module: do_op

Inherited from object: __delattr__, __format__, __getattribute__, __hash__, __new__, __reduce__, __reduce_ex__, __repr__, __setattr__, __sizeof__, __str__, __subclasshook__

Properties

input_pin_count
The no.

Inherited from Analog: vref

Inherited from object: __class__

Method Details

init(self, agent)
(Constructor)

Constructs an ADC object.

Parameters:

agent (Agent) - the agent interface object

Raises:

ProtocolError - If communication with agent fails or if data sent or received is corrupted

Overrides: object.__init__

read_pin_raw(self, pin)

Reads and returns the value on the specified analog input pin. The returned value represents the analog input as quantized levels in the range 0 to 0xFFFF.

Returns: int: the value read from the pin

See Also: ADC.read_pin

read_raw(self)

Reads and returns the value (0 - 0xFFFF) on all analog input pins.

Returns: list of ints: the values read from the analog pins

read(self)

Reads and returns the value (0 - Vref) on all analog input pins.

Returns: list of floats

the data read from the pins.

Raises:

ProtocolError - If communication with agent fails or or if data sent or received is corrupted

read_pin(self, pin)

Reads and returns the value on the specified analog input pin. The returned value represents the analog input as a value in the range 0 to Vref.

Returns: float: the value read from the pin

Property Details

input_pin_count

The no. of input pins available in this module.

Get Method:: _get_input_pin_count(self)
