Adc_8591
public Adc_8591( Sensor_port port, Connection* connection, unsigned char i2c_address );
- Constructor for the PCF8591 ADC chip
- Parameters:
port - [which sensor port to use]
*connection - [attach a connection]
i2c_address - [set the I2C address of the chip]
~Adc_8591
public ~Adc_8591();
get_type
public Sensor_type get_type();
- Get the sensor type
- Returns:
- ADC_8591_SENSOR
init
public void init( bool reply = false );
- Initiate the sensor
- Parameters:
reply - [true = require reply from NXT; false = no reply from NXT]
print
public std::string print();
- Get the sensor reading as a string
(init method will be called if the sensor has not been initialized)
- Returns:
- sensor reading as a string - "P0='some value' P1='some value' P2='some value' P3='some value'"
read
public int read( Result& result );
- Get value from all four AD ports
- Parameters:
&result - [must be of type Adc_ports - values are "stored" in result]- See Also:
Adc_ports
