Product overview

Description

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.

  • All features

    • 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
