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.
