Nodemcu-esp8266 development board to build Arduino ide development environment

The first 1 Step ： install ardunio 1.8.13.

Download address ：https://www.arduino.cn/thread-5838-1-1.html

The first 2 Step ： Install serial driver CP210x_Windows_Drivers.

Download address ：https://cn.silabs.com/developers/usb-to-uart-bridge-vcp-drivers

The first 3 Step ： install ESP8266 plug-in unit , It is recommended to use method 2 for installation .
  1） Method 1 ：
    open ardunio IDE, file -> Preferences -> Additional development board management website , Fill in address ：http://arduino.esp8266.com/stable/package_esp8266com_index.json, Then determine .
    Next tool -> Development board XXX->“ Development board Manager ” Enter... In the search field of “esp8266”, If the previous management website prompts that there is an error in downloading , Then input. ESP8266 It can't be found .
  2） Method 2 ：
    On the website  https://www.arduino.cn/thread-76029-1-1.html, Download plug-ins 8266_package_2.6.4, Double click to install .
    If you have installed other versions esp8266sdk, Please delete first. , Reuse this installation package , Delete method ： Enter... In the file manager address field %LOCALAPPDATA%/Arduino15/packages, Enter by car , Then delete the esp8266 Folder .

The first 4 Step ： Tools -> Development board -> choice NodeMCU1.0(ESP-12E Module).

The first 5 Step ： Tools -> Select port COMxx.

The first 6 Step ： Run the example , file -> Example ->ESP8266->Blink.

The first 7 Step ： Compile and download , You can see on the development board LED Light flashing (LED Light at ESP-12E On module ), If the prompt cannot be opened COM mouth , There may be COM The port is occupied by the serial port .

Pin mapping ：

Write pins in the program "D4" And write pin 2（GPIO2） The effect is the same .

for example ：digitalWrite(D4, LOW) And digitalWrite(2, LOW) It's the same .

ESP8266->Blink Routine code ：

/*
  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
*/

// Use the development board ：nodemcu-esp8266(ESP-12E modular )
// Download port ： Tools -> port COM9
// Program function ： Flash two LED The lamp 

#define LED_BUILTIN      2   //ESP-12E The module itself LED, Corresponding GPIO2, Low level light 
#define LED_BUILTIN_AUX  16  //nodemcu-esp8266 The development board extends LED, Corresponding GPIO16, Low level light 

void setup() 
{
  pinMode(LED_BUILTIN, OUTPUT);     
  pinMode(LED_BUILTIN_AUX, 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
  digitalWrite(LED_BUILTIN_AUX, LOW);
  delay(1000);                      // Wait for a second
  digitalWrite(LED_BUILTIN, HIGH);  // Turn the LED off by making the voltage HIGH
   digitalWrite(LED_BUILTIN_AUX, HIGH);
  delay(2000);                      // Wait for two seconds (to demonstrate the active low LED)
}
