Implementing an emulated universal asynchronous receiver transmitter on STM32F4 microcontroller series (AN4457)

ソフトウェア入手 データブリーフのダウンロード



The UART emulator is needed in applications that require more UARTs than the ones provided by STM32F4 microcontrollers.

The STSW-STM32156 firmware provides an emulated full-duplex UART which supports up to 9 data bits and up to115200 baud rates.

The STSW-STM32156 firmware also offers an example of communications between a hardware and a software UART.

For more details refer to application note AN4457.

  • 特徴

    • Full duplex, asynchronous communications
    • Full duplex mode up to 115200 bps
    • Data length (5 up to 9 bits)
    • Flexible GPIO use: all GPIOs could be configured as UART TX/RX
