Struct embassy_stm32::opamp::OpAmp

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

OpAmp driver.

Implementations

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

pub fn new(opamp: impl Peripheral<P = T> + 'd, speed: OpAmpSpeed) -> Self

Create a new driver instance.

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

pub fn buffer_ext( &'d mut self, in_pin: impl Peripheral<P = impl NonInvertingPin<T> + Pin>, out_pin: impl Peripheral<P = impl OutputPin<T> + Pin> + 'd, gain: OpAmpGain ) -> OpAmpOutput<'d, 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 buffer_int( &'d mut self, pin: impl Peripheral<P = impl NonInvertingPin<T> + Pin>, gain: OpAmpGain ) -> OpAmpInternalOutput<'d, T>

Configure the OpAmp as a buffer for the provided input pin, with the output only used internally, and enable the opamp.

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

The returned OpAmpInternalOutput struct may be used as an ADC input. The opamp output will be disabled when it is dropped.
