The STM32F4 SPI peripherals
As with other peripherals, STM32 microcontrollers often include several SPI peripherals; the number varies depending on the specific model. The STM32F411 microcontroller has five SPI peripherals, namely the following:
- SPI1
- SPI2
- SPI3
- SPI4
- SPI5
Key features
Here are some of the key features:
- Full-duplex and half-duplex communication: Supports simultaneous two-way communication (full-duplex) or one-way communication (half-duplex)
- Master/slave configuration: Each SPI peripheral can be configured as either a master or a slave device
- Flexible data size: Supports data sizes ranging from 4 to 16 bits
- High-speed communication: Capable of operating at speeds up to 42 MHz in master mode and up to 21 MHz in slave mode
- Direct Memory Access (DMA) support: DMA support for efficient data transfer without CPU intervention
- Negative SS (NSS) pin management: Hardware management of the NSS pin for multi-slave configurations...
