Detailed Description

Function Documentation

void analogout_free ( dac_t * obj )

Release the analogout object.

Note: This is not currently used in the mbed-drivers

Parameters

obj	The analogout object

Initialize the analogout peripheral.

Configures the pin used by analogout.

Parameters

obj	The analogout object to initialize
pin	The analogout pin name

const PinMap* analogout_pinmap ( void )

Get the pins that support analogout.

Return a PinMap array of pins that support analogout. The array is terminated with {NC, NC, 0}.

float analogout_read ( dac_t * obj )

Read the current voltage value on the pin.

Parameters

obj	The analogin object

Returns: A floating-point value representing the current voltage on the pin, measured as a percentage

uint16_t analogout_read_u16 ( dac_t * obj )

Read the current voltage value on the pin, as a normalized unsigned 16bit value.

Parameters

obj	The analogin object

Returns: An unsigned 16-bit value representing the current voltage on the pin

Set the output voltage, specified as a percentage (float)

Parameters

obj	The analogin object
value	The floating-point output voltage to be set

Set the output voltage, specified as unsigned 16-bit.

Parameters

obj	The analogin object
value	The unsigned 16-bit output voltage to be set
