    uart.control_485

    -
    uart.control_485(UART.GPIOn, direction)
-
    -

    该方法用于控制485通信方向，串口发送数据之前和之后进行拉高拉低指定GPIO，用来指示485通信的方向。

    -

    参数描述：

    -
      -

    • GPIOn - 需要控制的GPIO引脚号，参照[Pin模块](machine.Pin.md)的引脚定义，int类型。

      -
      • -

    • direction - 引脚电平变化，int类型，说明如下：
      1表示引脚电平变化为：串口发送数据之前由低拉高、发送数据之后再由高拉低
      0表示引脚电平变化为：串口发送数据之前由高拉低、发送数据之后再由低拉高

      -
      • -
    -

    返回值描述：

    -

    成功返回整型值0，失败返回整型值-1。

    -

    -
    from machine import UART
    uart1 = UART(UART.UART1, 115200, 8, 0, 1, 0)
