nodeMcu(esp8266)连接wifi(2.4G)/NodeMcu+oled(ssd1306)库例程

testCode

测试环境基于:vscode+platformIO IDE平台
( a awsome tool to develop almost all embedded boards)

testCode

the libraries:

<ESP8266WiFi.h>
<Arduino.h>

the funcitons:

WiFi.begin()
WiFi.status()
WiFi.localIP()

 #include <Arduino.h>
#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>
//#include <ESP8266HTTPClient.h>
//设置两个宏定义用于WiFi名和密码(修改为自身环境(比手机热点wifi)
#define WIFINAME "belldandy"
#define WIFIPW "11223344"
// nodemcu只能够链接到2.4G频段的wifi(或者说,默认是连不到5Ghz的WiFi的,这一点要注意!)
void setup()
{
    // put your setup code here, to run once:
    pinMode(LED_BUILTIN, OUTPUT);
    Serial.begin(115200);
    Serial.println("");
    WiFi.begin(WIFINAME, WIFIPW);
    Serial.print("Connecting wifi..");
    while (WiFi.status() != WL_CONNECTED)
    {
        delay(500);
        Serial.print(".");
    }
    Serial.println();
    Serial.print("Connected,IP Address:");
    Serial.println(WiFi.localIP());
}
 
void loop()
{
    // put your main code here, to run repeatedly:
    Serial.println("in loop()");
    delay(1e4);
}

platformIO bring you a brand embedded development experience.
