Struct Cordic

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

CORDIC driver

Implementations

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

pub fn new(peri: impl Peripheral<P = T> + 'd, config: Config) -> Self

Create a Cordic driver instance

Note:
If you need a peripheral -> CORDIC -> peripheral mode,
you may want to set Cordic into [Mode::ZeroOverhead] mode, and add extra arguments with Self::extra_config

pub fn set_config(&mut self, config: Config)

Set a new config for Cordic driver

pub fn extra_config( &mut self, arg_cnt: AccessCount, arg_width: Width, res_width: Width, )

Set extra config for data count and data width.

pub fn reconfigure(&mut self)

Disable IRQ and DMA, clean RRDY, and set ARG2 to +1 (0x7FFFFFFF)

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

pub fn blocking_calc_32bit( &mut self, arg: &[u32], res: &mut [u32], arg1_only: bool, res1_only: bool, ) -> Result<usize, CordicError>

Run a blocking CORDIC calculation in q1.31 format

Notice:
If you set arg1_only to true, please be sure ARG2 value has been set to desired value before.
This function won’t set ARG2 to +1 before or after each round of calculation.
If you want to make sure ARG2 is set to +1, consider run .reconfigure().

pub async fn async_calc_32bit( &mut self, write_dma: impl Peripheral<P = impl WriteDma<T>>, read_dma: impl Peripheral<P = impl ReadDma<T>>, arg: &[u32], res: &mut [u32], arg1_only: bool, res1_only: bool, ) -> Result<usize, CordicError>

Run a async CORDIC calculation in q.1.31 format

Notice:
If you set arg1_only to true, please be sure ARG2 value has been set to desired value before.
This function won’t set ARG2 to +1 before or after each round of calculation.
If you want to make sure ARG2 is set to +1, consider run .reconfigure().

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

pub fn blocking_calc_16bit( &mut self, arg: &[u32], res: &mut [u32], ) -> Result<usize, CordicError>

Run a blocking CORDIC calculation in q1.15 format

Notice::
User will take respond to merge two u16 arguments into one u32 data, and/or split one u32 data into two u16 results.

pub async fn async_calc_16bit( &mut self, write_dma: impl Peripheral<P = impl WriteDma<T>>, read_dma: impl Peripheral<P = impl ReadDma<T>>, arg: &[u32], res: &mut [u32], ) -> Result<usize, CordicError>

Run a async CORDIC calculation in q1.15 format

Notice::
User will take respond to merge two u16 arguments into one u32 data, and/or split one u32 data into two u16 results.

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

check input value ARG1, SCALE and FUNCTION are compatible with each other

pub fn check_f64_arg2(&self, arg: &f64) -> Result<(), ArgError>

check input value ARG2 and FUNCTION are compatible with each other

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

pub fn check_f32_arg1(&self, arg: &f32) -> Result<(), ArgError>

check input value ARG1, SCALE and FUNCTION are compatible with each other

pub fn check_f32_arg2(&self, arg: &f32) -> Result<(), ArgError>

check input value ARG2 and FUNCTION are compatible with each other

Trait Implementations
