Support for the Serial Peripheral Interface (SPI) bus peripheral. Provides APIs to configure, read, and write from SPI, with blocking, nonblocking, and DMA functionality.

Structs

Spi

Represents a Serial Peripheral Interface (SPI) peripheral.

SpiConfig

Configuration data for SPI.

Enums

BaudRate

Set the factor to divide the APB clock by to set baud rate. Sets SPI_CR1 register, BR field. On H7, sets CFG1 register, MBR field.

DataSize

These bits configure the data length for SPI transfers. Sets SPI_CR2 register, DS field.

ReceptionThresh

FIFO reception threshold Sets SPI_CR2 register, FRXTH field.

SlaveSelect

Used for managing NSS / CS pin. Sets CR1 register, SSM field. On H7, sets CFG2 register, SSOE field.

SpiCommMode

Select the duplex communication mode between the 2 devices. Sets CR1 register, BIDIMODE, and RXONLY fields.

SpiError

SPI error

SpiInterrupt

Possible interrupt types. Enable these in SPIx_CR2. Check and clear with SR. There is no explicit way to clear these.
