一、描述你遇到的问题
uart1可以正常发送数据但是无法接收数据。将 GPIO16（uart1 rx）初始化为 PIN_MODE1（UART1_RX_MODE）后，将逻辑分析仪接到 usb 转串口模块的 tx 引脚，同时将 usb 转串口模块的 TX 引脚接到 GPIO16 并对其发送数据，从逻辑分析仪看 GPIO16 引脚始终为高电平，但是断开 usb转串口模块与 ws63 gpio16 引脚的连接，确认串口模块是可以正常发送数据的。使用官方的 uart数据传输例程，将 uart bus id 设置为2可以正常接收 Hello BearPi 数据，但是使用 uart1 则无法正常接收数据。
二、你具体做的所有步骤结果截图
代码：
逻辑分析仪抓取波形：
