Struct Qspi

pub struct Qspi { /* private fields */ }

The QSPI driver interface.

Implementations

impl Qspi

pub fn new(_rcc: &mut RCC, qspi: QUADSPI, size: u8, adsize: u8) -> Self

Initialize and configure the QSPI flash driver.

• size is log2(flash size in bytes), e.g. 16 MB = 24.
• adsize is the number of bytes needed to specify the address (1, 2, 3, or 4).

pub fn read_all<B>( &mut self, data: Pin<B>, transaction: QspiTransaction, dma: &Handle<<RxTx<QUADSPI> as Target>::Instance, Enabled>, stream: <RxTx<QUADSPI> as Target>::Stream, ) -> Result<Transfer<RxTx<QUADSPI>, B, Started>, Error>

where B: Deref + 'static, B::Target: AsSlice<Element = u8>,

DMA read. Wrapper around the HAL DMA driver. Performs QSPI register programming, creates a DMA transfer from peripheral to memory, and starts the transfer. Caller can use the DMA wait API to block until the transfer is complete.

pub fn write_all<B>( &mut self, data: Pin<B>, transaction: QspiTransaction, dma: &Handle<<RxTx<QUADSPI> as Target>::Instance, Enabled>, stream: <RxTx<QUADSPI> as Target>::Stream, ) -> Result<Transfer<RxTx<QUADSPI>, B, Started>, Error>

where B: Deref + 'static, B::Target: AsSlice<Element = u8>,

DMA write. Wrapper around the HAL DMA driver. Performs QSPI register programming, creates a DMA transfer from memory to peripheral, and starts the transfer. Caller can use the DMA wait API to block until the transfer is complete.

pub fn read( &mut self, buf: &mut [u8], transaction: QspiTransaction, ) -> Result<(), Error>

Polling indirect read. Can also be used to perform transactions with no data.

pub fn write( &mut self, buf: &[u8], transaction: QspiTransaction, ) -> Result<(), Error>

Polling indirect write.
