Trait Implementations

impl<'a> Adc<'a> for Adc<'a>

type Channel = Channel

The chip-dependent type of an ADC channel.

fn sample(&self, channel: &Self::Channel) -> Result<(), ErrorCode>

Request a single ADC sample on a particular channel. Used for individual samples that have no timing requirements. All ADC samples will be the raw ADC value left-justified in the u16.

fn sample_continuous( &self, _channel: &Self::Channel, _frequency: u32 ) -> Result<(), ErrorCode>

Request repeated ADC samples on a particular channel. Callbacks will occur at the given frequency with low jitter and can be set to any frequency supported by the chip implementation. However callbacks may be limited based on how quickly the system can service individual samples, leading to missed samples at high frequencies. All ADC samples will be the raw ADC value left-justified in the u16.

fn stop_sampling(&self) -> Result<(), ErrorCode>

Stop a sampling operation. Can be used to stop any simple or high-speed sampling operation. No further callbacks will occur.

fn get_resolution_bits(&self) -> usize

Function to ask the ADC how many bits of resolution are in the samples it is returning.

fn get_voltage_reference_mv(&self) -> Option<usize>

Function to ask the ADC what reference voltage it used when taking the samples. This allows the user of this interface to calculate an actual voltage from the ADC reading.

fn set_client(&self, client: &'a dyn Client)

impl<'a> AdcHighSpeed<'a> for Adc<'a>

Not yet supported

fn sample_highspeed( &self, _channel: &Self::Channel, _frequency: u32, buffer1: &'static mut [u16], _length1: usize, buffer2: &'static mut [u16], _length2: usize ) -> Result<(), (ErrorCode, &'static mut [u16], &'static mut [u16])>

Capture buffered samples from the ADC continuously at a given frequency, calling the client whenever a buffer fills up. The client is then expected to either stop sampling or provide an additional buffer to sample into. Note that due to hardware constraints the maximum frequency range of the ADC is from 187 kHz to 23 Hz (although its precision is limited at higher frequencies due to aliasing).

• channel: the ADC channel to sample
• frequency: frequency to sample at
• buffer1: first buffer to fill with samples
• length1: number of samples to collect (up to buffer length)
• buffer2: second buffer to fill once the first is full
• length2: number of samples to collect (up to buffer length)

fn provide_buffer( &self, buf: &'static mut [u16], _length: usize ) -> Result<(), (ErrorCode, &'static mut [u16])>

Provide a new buffer to send on-going buffered continuous samples to. This is expected to be called after the samples_ready callback.

• buf: buffer to fill with samples
• length: number of samples to collect (up to buffer length)

fn retrieve_buffers( &self ) -> Result<(Option<&'static mut [u16]>, Option<&'static mut [u16]>), ErrorCode>

Reclaim buffers after the ADC is stopped. This is expected to be called after stop_sampling.
