  • The X-CUBE-SPI-EMUL embedded software provides an emulated simplex or full-duplex SPI in the master and slave modes.

    The SPI emulator is needed in applications that require more SPIs.
    The X-CUBE-SPI-EMUL embedded software also offers two examples of communication between a hardware and a software SPI.
    For more details refer to the application note AN4678.

    主な特徴

    • Simplex/full-duplex, synchronous, serial communication
    • Master and slave operations
    • SPI clock up to 6 MHz in full-duplex mode with CPU operating at 168 MHz
    • Programmable data word length: 8 and 16 bits
    • Programmable clock polarity and phase
    • Programmable data order with MSB-first or LSB-first shifting
    • Flexible GPIO usage: all GPIOs can be configured as SPI MOSI/MISO
    • Status flags/interrupt
