  • The STM32 microcontrollers are able to emulate parallel synchronous communication through GPIOs using the embedded DMA IP.

    The X-CUBE-PARAL-COM software solution developed on STM32Cube offers an implementation of such parallel synchronous interface on STM32L476G and STM32F429I discovery boards. It can easily be ported on other platforms.

    主要特性

    • Timeout detection of end of transmission
    • CRC check of transmitted data
    • STM32L476G discovery board implementation features
      • Storage of transmitted data in STM32L476 internal SRAM
      • Up to 10MHz transmission clock
      • Data frame length limited by internal SRAM size and DMA 16bit counter (65530 data transmitted)
    • STM32F429I discovery board implementation features
      • Storage of transmitted data in external SDRAM
      • Up to 7.82MHz transmission clock
      • Data frame length limited by external SDRAM size
