Struct OpAmp 

pub struct OpAmp<'d, T: Instance> { /* private fields */ }

OpAmp driver.

Implementations

impl<'d, T: Instance> OpAmp<'d, T>

pub fn new(opamp: Peri<'d, T>) -> Self

Create a new driver instance.

Does not enable the opamp, but does set the speed mode on some families.

pub fn buffer_ext( &mut self, in_pin: Peri<'_, impl NonInvertingPin<T> + Pin>, out_pin: Peri<'_, impl OutputPin<T> + Pin>, ) -> OpAmpOutput<'_, T>

Configure the OpAmp as a buffer for the provided input pin, outputting to the provided output pin, and enable the opamp.

The input pin is configured for analogue mode but not consumed, so it may subsequently be used for ADC or comparator inputs.

The output pin is held within the returned OpAmpOutput struct, preventing it being used elsewhere. The OpAmpOutput can then be directly used as an ADC input. The opamp will be disabled when the OpAmpOutput is dropped.

pub fn pga_ext( &mut self, in_pin: Peri<'_, impl NonInvertingPin<T> + Pin>, out_pin: Peri<'_, impl OutputPin<T> + Pin>, gain: OpAmpGain, ) -> OpAmpOutput<'_, T>

Configure the OpAmp as a PGA for the provided input pin, outputting to the provided output pin, and enable the opamp.

The input pin is configured for analogue mode but not consumed, so it may subsequently be used for ADC or comparator inputs.

The output pin is held within the returned OpAmpOutput struct, preventing it being used elsewhere. The OpAmpOutput can then be directly used as an ADC input. The opamp will be disabled when the OpAmpOutput is dropped.

Trait Implementations

impl<'d, T: Instance> Drop for OpAmp<'d, T>

fn drop(&mut self)

Executes the destructor for this type.
