Detailed Description

Class that stores state and functions for interacting with the DS3502 I2C Potentiometer.

Member Function Documentation

begin()

bool Adafruit_DS3502::begin	(	uint8_t	i2c_address = DS3502_I2CADDR_DEFAULT,
		TwoWire *	wire = &Wire
	)

Sets up the hardware and initializes I2C.

Parameters

i2c_address	The I2C address to be used.
wire	The Wire object to be used for I2C connections.

Returns

True if initialization was successful, otherwise false.

getWiper()

uint8_t Adafruit_DS3502::getWiper

(

void

)

Gets the current value of the wiper register.

Returns

The 7-bit wiper value.

setWiper()

void Adafruit_DS3502::setWiper

(

uint8_t

new_wiper_value

)

Sets the potentiometer wiper to a new value.

Parameters

new_wiper_value

The new wiper value to set. Must be from 0-127

setWiperDefault()

void Adafruit_DS3502::setWiperDefault

(

uint8_t

new_wiper_default

)

Sets the Wiper and IVR (Initial Value Register) to the given value.

Parameters

new_wiper_default

The new wiper default to be set the wiper and default wiper value to. The wiper register will be set to the given value when written and when the device is powered on. Must be from 0-127
