Member Enumeration Documentation

enum modm::platform::Dac::Channel : uint8_t
strong

The DAC has two output channels, Channel1 and Channel2

Member Function Documentation

void modm::platform::Dac::disableChannel ( Channel  chan)
static

Disable DAC output for the given channel

Parameters
chanThe channel to be disabled
Precondition
The DAC clock must be enabled with initialize()
void modm::platform::Dac::enableChannel ( Channel  chan)
static

Enable DAC output for the given channel

Parameters
chanThe channel to be enabled
Precondition
The DAC clock must be enabled with initialize()
void modm::platform::Dac::enableOutputBuffer ( Channel  chan,
bool  enable 
)
static

Control the output buffer setting

Parameters
chanThe channel to enable/disable the output buffer on
enabletrue to turn on the output buffer, false to turn it off
Precondition
The DAC clock must be enabled with initialize()
void modm::platform::Dac::initialize ( )
static

Initialize the D/A converter.

Enables the RCC clock output for the DAC

void modm::platform::Dac::setOutput ( Channel  chan,
uint16_t  value 
)
inlinestatic

Set the output voltage for a DAC channel

Parameters
chanThe channel to set
valueThe 12-bit DAC output value, range 0-4095.
Precondition
The DAC clock must be enabled with initialize()
void modm::platform::Dac::setOutput1 ( uint16_t  value)
inlinestatic

Set output value for Channel1

Equivalent to setOutput(modm::platform::Dac::Channel1, value)

Parameters
valueThe 12-bit DAC output value, range 0-4095
Precondition
The DAC clock must be enabled with initialize()
void modm::platform::Dac::setOutput2 ( uint16_t  value)
inlinestatic

Set output value for Channel2

Equivalent to setOutput(modm::platform::Dac::Channel2, value)

Parameters
valueThe 12-bit DAC output value, range 0-4095
Precondition
The DAC clock must be enabled with initialize()
