I2C driver configuration

Implementations

impl Config

pub fn with_frequency(self, frequency: Rate) -> Self

Assign the given value to the frequency field.

pub fn frequency(&self) -> Rate

The I2C clock frequency.

Default value: 100 kHz.

pub fn with_timeout(self, timeout: BusTimeout) -> Self

Available on crate feature unstable only.

Assign the given value to the timeout field.

pub fn timeout(&self) -> BusTimeout

Available on crate feature unstable only.

I2C SCL timeout period.

Default value: disabled

pub fn with_software_timeout(self, software_timeout: SoftwareTimeout) -> Self

Assign the given value to the software_timeout field.

pub fn software_timeout(&self) -> SoftwareTimeout

Software timeout.

Default value: disabled.

pub fn with_scl_st_timeout(self, scl_st_timeout: FsmTimeout) -> Self

Available on crate feature unstable only.

Assign the given value to the scl_st_timeout field.

pub fn scl_st_timeout(&self) -> FsmTimeout

Available on crate feature unstable only.

Sets the threshold value for the unchanged period of the SCL_FSM.

Default value: 16.

pub fn with_scl_main_st_timeout(self, scl_main_st_timeout: FsmTimeout) -> Self

Available on crate feature unstable only.

Assign the given value to the scl_main_st_timeout field.

pub fn scl_main_st_timeout(&self) -> FsmTimeout

Available on crate feature unstable only.

Sets the threshold for the unchanged duration of the SCL_MAIN_FSM.

Default value: 16.

pub fn with_clock_source(self, clock_source: ClockSource) -> Self

Available on crate feature unstable only.

Assign the given value to the clock_source field.

pub fn clock_source(&self) -> ClockSource

Available on crate feature unstable only.

The clock source for the I2C peripheral.

Default value: ClockSource::default().

pub fn with_scl_sample_level(self, scl_sample_level: Level) -> Self

Available on crate feature unstable only.

Assign the given value to the scl_sample_level field.

pub fn scl_sample_level(&self) -> Level

Available on crate feature unstable only.

Selects whether the controller samples the SDA line while SCL is high or low.

Standard I2C devices change SDA while SCL is low and hold it stable while SCL is high, so the line is sampled while SCL is high by default (Level::High).

pub fn with_bus_arbitration(self, bus_arbitration: bool) -> Self

Available on crate feature unstable only.

Assign the given value to the bus_arbitration field.

pub fn bus_arbitration(&self) -> bool

Available on crate feature unstable only.

Enables I2C bus arbitration detection.

Default value: false.
