Struct imxrt_hal::lpspi::Disabled

pub struct Disabled<'a, const N: u8> { /* private fields */ }

An LPSPI peripheral which is temporarily disabled.

Implementations

impl<'a, const N: u8> Disabled<'a, N>

pub fn set_mode(&mut self, mode: Mode)

👎Deprecated since 0.5.5: Use Lpspi::set_mode to change modes while enabled.

Set the SPI mode for the peripheral

pub fn set_clock_hz(&mut self, source_clock_hz: u32, clock_hz: u32)

Set the LPSPI clock speed (Hz).

source_clock_hz is the LPSPI peripheral clock speed. To specify the peripheral clock, see the ccm::lpspi_clk documentation.

pub fn set_watermark(&mut self, direction: Direction, watermark: u8) -> u8

👎Deprecated since 0.5.5: Use Lpspi::set_watermark to change watermark while enabled

Set the watermark level for a given direction.

Returns the watermark level committed to the hardware. This may be different than the supplied watermark, since it’s limited by the hardware.

When direction == Direction::Rx, the receive data flag is set whenever the number of words in the receive FIFO is greater than watermark.

When direction == Direction::Tx, the transmit data flag is set whenever the the number of words in the transmit FIFO is less than, or equal, to watermark.

pub fn set_sample_point(&mut self, sample_point: SamplePoint)

Set the sampling point of the LPSPI peripheral.

When set to SamplePoint::DelayedEdge, the LPSPI will sample the input data on a delayed LPSPI_SCK edge, which improves the setup time when sampling data.
