[−][src]Struct nrf52832_hal::nrf52_hal_common::spim::Spim
Interface to a SPIM instance
This is a very basic interface that comes with the following limitations:
- The SPIM instances share the same address space with instances of SPIS,
SPI, TWIM, TWIS, and TWI. You need to make sure that conflicting instances
are disabled before using
Spim
. See product specification, section 15.2. - The SPI mode is hardcoded to SPI mode 0.
- The frequency is hardcoded to 500 kHz.
- The over-read character is hardcoded to
0
.

Read from an SPI slave
This method implements a complete read transaction, which consists of the master transmitting what it wishes to read, and the slave responding with the requested data.
Uses the provided chip select pin to initiate the transaction. Transmits
all bytes in tx_buffer
, then receives bytes until rx_buffer
is full.
Both buffer must have a length of at most 255 bytes.
pub fn write(
&mut self,
chip_select: &mut P0_Pin<Output<PushPull>>,
tx_buffer: &[u8]
) -> Result<(), Error>
[src]
pub fn write(
&mut self,

) -> Result<(), Error>
Write to an SPI slave
This method uses the provided chip select pin to initiate the
transaction, then transmits all bytes in tx_buffer
.
The buffer must have a length of at most 255 bytes.
