Implementations

impl<'d, 'a, T: Instance> Cordic32<'d, 'a, T>

pub fn set_access_counts( &mut self, arg_count: AccessCount, res_count: AccessCount, )

Change arg_count and res_count without resetting ARG2.

This is a lightweight CSR update for switching between 1-arg and 2-arg modes within the same function configuration (e.g. after an initial 2-arg call sets ARG2, switch to 1-arg mode for the hot loop).

pub fn blocking_calc( &mut self, arg: &[Q32<31>], res: &mut [Q32<31>], ) -> Result<usize, CordicError>

Run a blocking CORDIC calculation in q1.31 format.

Uses arg_count and res_count from the current Config. If arg_count is One, ARG2 must have been set to the desired value beforehand (e.g. via a prior Two-arg call or [Self::reconfigure]).

pub async fn async_calc<'b, W, R>( &mut self, write_dma: Peri<'b, W>, read_dma: Peri<'b, R>, irq: impl Binding<W::Interrupt, InterruptHandler<W>> + Binding<R::Interrupt, InterruptHandler<R>> + 'b, arg: &[Q32<31>], res: &mut [Q32<31>], ) -> Result<usize, CordicError>

where W: WriteDma<T>, R: ReadDma<T>,

Run an async CORDIC calculation in q1.31 format.

Uses arg_count and res_count from the current Config. If arg_count is One, ARG2 must have been set to the desired value beforehand (e.g. via a prior Two-arg call or [Self::reconfigure]).
