Peripheral SPI[edit | edit source]
The Serial Peripheral Interface (SPI) is a full-duplex, synchronous, four-wire serial communication block.
Description[edit | edit source]
The SPI interface available on ETRA SOM is based on STM32MP1 SoC.
The SPI port supports the following standards and features:
- full-duplex synchronous transfers on three lines
- half-duplex synchronous transfer on two lines (with bidirectional data line)
- simplex synchronous transfers on two lines (with unidirectional data line)
- 4-bit to 32-bit data size selection
- multi master or multi slave mode capability
- hardware or software management of SS for both master and slave
- configurable SS signal polarity and timing, MISO x MOSI swap capability
- two 16x or 8x 8-bit embedded Rx and TxFIFOs with DMA capability
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
