Module stm32_hal2::spi

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.

SpiMode
