Full duplex SPI emulation for STM32F4 microcontrollers, software expansion for STM32Cube (AN4678)

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.

主要特性

  • 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
