access to 11 GPIO pins, and one analog-to-digital converter (ADC) pin with 10 bit resolution. The board has a built-in voltage regulator and you can power up the module using the mini USB socket or the Vin pin.
其中GPIO2引脚是TX1,GPIO8是RX1。请注意,由于GPIO8被用于连接闪存芯片,串行端口1只能使用GPIO2来向外发送串行数据。 I²C ESP8266只有软件模拟的I²C端口,没有硬件I²C端口。也就是说我们可以使用任意的两个GPIO引脚通过软件模拟来实现I²C通讯。ESP8266的数据表(datasheet)中,GPIO2标注为SDA,GPIO14标注...
