Struct USART1

pub struct USART1 { /* private fields */ }

Universal synchronous asynchronous receiver transmitter

See peripheral structure

Implementations

impl USART1

pub const PTR: *const RegisterBlock = {0x40011000 as *const stm32f4_staging::stm32f429::usart1::RegisterBlock}

Pointer to the register block

pub const fn ptr() -> *const RegisterBlock

Return the pointer to the register block

pub unsafe fn steal() -> USART1

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.
