WeMos D1开发板以ESP8266WIFI开发板为基础，使用Arduino开发板的设计，工作电压为3.3V设计出来的开发板，这个开发板仅仅是使用了Arduino uno的布局设计，并不是Arduino的开发板。
下面是关于这块开发板的说明书：
总结下：
此开发板芯片为ESP8266（32位），缓存比Arduino Uno大，并且包含11个数字IO引脚以及1个模拟输入引脚，使用Micro-B type USB线进行连接。
下面是引脚方面的说明！
所有的引脚都需要跑到3.3V上，并且除了D0口其他口都支持interrupt/PWM/I2C/one-wire。
下面是在Arduino IDE中部署其开发环境
软件需要如下3个：
CH340G USB to UART driver: https://www.wemos.cc/downloads
Python 2.7: https://www.python.org/downloads/release/python-2713/
Arduino 1.8.2: https://www.arduino.cc/en/Main/Software
在Arduino的目录下新建2个文件夹esp8266com及esp8266
在Github上下载其库文件：
将压缩包放到esp8266目录下，然后解压：
将里面的文件移到到esp8266中，再将Arduino-master与Arduino-master.zip删掉。
最后变成这个样子即可！
打开CMD然后执行如下命名：
python get.py此命令将会下载开发板所需要的工具，一切正常，且安装好将会是这样的。
这样就完成了安装！！！
使用Arduino IDE时要选中正确的开发板，Toos>Board中选择"WeMos D1 R2 & Mini"即可：
下面是几个示例代码：
Blink
-
/*
-
ESP8266 Blink by Simon Peter
-
Blink the blue LED on the ESP-01 module
-
This example code is in the public domain
-
-
The blue LED on the ESP-01 module is connected to GPIO1
-
(which is also the TXD pin; so we cannot use Serial.print() at the same time)
-
-
Note that this sketch uses LED_BUILTIN to find the pin with the internal LED
-
*/
-
-
void setup() {
-
pinMode(LED_BUILTIN, OUTPUT);
// Initialize the LED_BUILTIN pin as an output
-
}
-
-
// the loop function runs over and over again forever
-
void loop() {
-
digitalWrite(LED_BUILTIN, LOW);
// Turn the LED on (Note that LOW is the voltage level
-
// but actually the LED is on; this is because
-
// it is active low on the ESP-01)
-
delay(
1000);
// Wait for a second
-
digitalWrite(LED_BUILTIN, HIGH);
// Turn the LED off by making the voltage HIGH
-
delay(
2000);
// Wait for two seconds (to demonstrate the active low LED)
-
}
查看下芯片的ID，这里串口打印频率要选择115200
-
/* Get Chip ID
-
* wemos.cc
-

*/
-
-
void setup() {
-
Serial.begin(
115200);
-
}
-
-
void loop() {
-
Serial.println(
"");
-
Serial.println(
"");
-
Serial.println(
"Check ID in:");
-
Serial.println(
"https://www.wemos.cc/verify_products");
-
Serial.
printf(
"Chip ID = %08Xn", ESP.getChipId());
-
Serial.println(
"");
-
Serial.println(
"");
-
delay(
5000);
-
}
运行一个简单的Web Server
-
#include <ESP8266WiFi.h>
-
#include <WiFiClient.h>
-
#include <ESP8266WebServer.h>
-
#include <ESP8266mDNS.h>
-
-
const
char* ssid =
"........";
-
const
char* password =
"........";
-
-

-
-
const
int led =
13;
-
-
void handleRoot() {
-
digitalWrite(led,
1);
-
server.send(
200,
"text/plain",
"Hello from esp8266!");
-
digitalWrite(led,
0);
-
}
-
-
void handleNotFound(){
-
digitalWrite(led,
1);
-
String message =
"File Not Foundnn";
-
message +=
"URI: ";
-
message += server.uri();
-
message +=
"nMethod: ";
-
message += (server.method() == HTTP_GET)?
"GET":
"POST";
-
message +=
"nArguments: ";
-
message += server.args();
-
message +=
"n";
-
for (
uint8_t i=
0; i<server.args(); i++){
-
message +=
" " + server.argName(i) +
": " + server.arg(i) +
"n";
-
}
-
server.send(
404,
"text/plain", message);
-
digitalWrite(led,
0);
-
}
-
-
void setup(void){
-

-
digitalWrite(led,

-
Serial.begin(
115200);
-
WiFi.begin(ssid, password);
-
Serial.println(

-
-
// Wait for connection
-
while (WiFi.status() != WL_CONNECTED) {
-
delay(
500);
-
Serial.print(
".");
-
}
-
Serial.println(

-
Serial.print(

-

-
Serial.print(

-
Serial.println(WiFi.localIP());
-
-

-
Serial.println(

-
}
-
-
server.on(

-
-
server.on(

-
server.send(
200,
"text/plain",
"this works as well");
-
});
-
-
server.onNotFound(handleNotFound);
-
-
server.begin();
-
