Struct DMA1

pub struct DMA1 { /* private fields */ }

Expand description

DMA controller

See peripheral structure

Implementations§

impl DMA1

pub const PTR: const RegisterBlock = {0x40020000 as const stm32g030::dma1::RegisterBlock}

Pointer to the register block

pub const fn ptr() -> *const RegisterBlock

Return the pointer to the register block

pub unsafe fn steal() -> Self

Steal an instance of this peripheral

§Safety

Ensure that the new instance of the peripheral cannot be used in a way that may race with any existing instances, for example by only accessing read-only or write-only registers, or by consuming the original peripheral and using critical sections to coordinate access between multiple new instances.

Additionally, other software such as HALs may rely on only one peripheral instance existing to ensure memory safety; ensure no stolen instances are passed to such software.

Methods from Deref<Target = RegisterBlock>§

pub fn isr(&self) -> &ISR

0x00 - DMA interrupt status register

pub fn ifcr(&self) -> &IFCR

0x04 - DMA interrupt flag clear register

pub fn ch(&self, n: usize) -> &CH

0x08..0x6c - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

`n` is the index of cluster in the array. `n == 0` corresponds to `CH1` cluster.

pub fn ch_iter(&self) -> impl Iterator<Item = &CH>

Iterator for array of: 0x08..0x6c - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

pub fn ch1(&self) -> &CH

0x08..0x1c - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

pub fn ch2(&self) -> &CH

0x1c..0x30 - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

pub fn ch3(&self) -> &CH

0x30..0x44 - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

pub fn ch4(&self) -> &CH

0x44..0x58 - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers

pub fn ch5(&self) -> &CH

0x58..0x6c - Channel cluster: CCR?, CNDTR?, CPAR?, and CMAR? registers
