Arduino for esp8266串口功能简介
串口
该对象的工作方式与常规Arduino的工作方式大致相同。除了硬件
FIFO（TX和RX为128字节）之外，还有一个额外的可定制的256字节RX缓冲区。此软件缓冲区的大小可由用户更改。建议在更高的接收速度下使用更大的容量。NodeMcu上有两组串口，Serial和Serial1。Serial使用UART0，默认对应引脚是GPIO1（TX–D10）和GPIO3（RX–D9）
- 该方法根据需要更改
RX缓冲区大小。这应该在 之前调用。size参数应至少足够大，以便在读取之前保存收到的所有数据。::setRxBufferSize(size_t size)::begin() - 对于仅传输操作&
