WeMos D1開發板以ESP8266WIFI開發板為基礎，使用Arduino開發板的設計，工作電壓為3.3V設計出來的開發板，這個開發板僅僅是使用了Arduino uno的布局設計，并不是Arduino的開發板。

下面是關于這塊開發板的說明書：

總結下：

此開發板芯片為ESP8266（32位），緩存比Arduino Uno大，并且包含11個數字IO引腳以及1個模擬輸入引腳，使用Micro-B type USB線進行連接。

下面是引腳方面的說明！

所有的引腳都需要跑到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中部署其開發環境

軟件需要如下3個：

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的目錄下新建2個文件夾esp8266com及esp8266

在Github上下載其庫文件：

將壓縮包放到esp8266目錄下，然后解壓：

將里面的文件移到到esp8266中，再將Arduino-master與Arduino-master.zip刪掉。

最后變成這個樣子即可！

打開CMD然后執行如下命名：

python get.py

此命令將會下載開發板所需要的工具，一切正常，且安裝好將會是這樣的。

這樣就完成了安裝！！！

使用Arduino IDE時要選中正確的開發板，Toos>Board中選擇"WeMos D1 R2 & Mini"即可：

下面是幾個示例代碼：

Blink

/*ESP8266 Blink by Simon PeterBlink the blue LED on the ESP-01 moduleThis example code is in the public domainThe 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 seconddigitalWrite(LED_BUILTIN, HIGH); // Turn the LED off by making the voltage HIGHdelay(2000); // Wait for two seconds (to demonstrate the active low LED) }

查看下芯片的ID，這里串口打印頻率要選擇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); }

運行一個簡單的Web Server

#include <ESP8266WiFi.h> #include <WiFiClient.h> #include <ESP8266WebServer.h> #include <ESP8266mDNS.h>const char* ssid = "........"; const char* password = "........";ESP8266WebServer server(80);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){pinMode(led, OUTPUT);digitalWrite(led, 0);Serial.begin(115200);WiFi.begin(ssid, password);Serial.println("");// Wait for connectionwhile (WiFi.status() != WL_CONNECTED) {delay(500);Serial.print(".");}Serial.println("");Serial.print("Connected to ");Serial.println(ssid);Serial.print("IP address: ");Serial.println(WiFi.localIP());if (MDNS.begin("esp8266")) {Serial.println("MDNS responder started");}server.on("/", handleRoot);server.on("/inline", [](){server.send(200, "text/plain", "this works as well");});server.onNotFound(handleNotFound);server.begin();Serial.println("HTTP server started"); }void loop(void){server.handleClient(); }

ssid填寫wifi名，password填寫wifi密碼
