Nodemcu-esp8266 development (vscode+platformio+arduino framework): Part 1 -- establishment of engineering template -template

First, build the development environment ：https://blog.csdn.net/felix_tao/article/details/113092886

First step ： Build a new project .

1） Project name Name：template

2） Development board Board：NodeMCU 1.0（ESP-12E Module）

3） frame Framework：Arduino

The second step ： Copy in routine Blink Code to src->main.cpp in .

1） find Blink Routine path C:\Users\felix\.platformio\packages\framework-arduinoespressif8266\libraries\esp8266\examples\Blink

2） Use Nodepad++ open , Copy the code inside to src->main.cpp in , Be careful ：main.cpp Do not delete the header file in .

Blink Routine code ：

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)
}

3） stay Blink Add serial port printing on the basis , The sorted code is as follows .

Macro definition #define LED_BUILTIN 2, It can be added or not , Because in pins_arduino.h There will also be definitions in .

Be careful ： Macro definition added #define LED_BUILTIN 2, It is impossible to jump to the definition , Need to be commented out , To jump .

main.cpp Code ：

#include <Arduino.h>

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

void setup()
{
  // put your setup code here, to run once:
  Serial.begin(115200);// Serial port baud rate configuration 
  pinMode(LED_BUILTIN, OUTPUT);// Set the pin to output mode 
}

void loop()
{
  // put your main code here, to run repeatedly:
  Serial.print("Hello world!\r\n");// Serial printing 

  // control LED Light flashing 
  digitalWrite(LED_BUILTIN, HIGH);// close LED The lamp 
  delay(1000);
  digitalWrite(LED_BUILTIN, LOW); // open LED The lamp 
  delay(1000);
}

pins_arduino.h Code （ It doesn't need to be modified ）：

#ifndef Pins_Arduino_h
#define Pins_Arduino_h

#define PIN_WIRE_SDA (4)
#define PIN_WIRE_SCL (5)

static const uint8_t SDA = PIN_WIRE_SDA;
static const uint8_t SCL = PIN_WIRE_SCL;

#ifndef LED_BUILTIN
#define LED_BUILTIN 2
#endif
#define LED_BUILTIN_AUX 16  

static const uint8_t D0   = 16;
static const uint8_t D1   = 5;
static const uint8_t D2   = 4;
static const uint8_t D3   = 0;
static const uint8_t D4   = 2;
static const uint8_t D5   = 14;
static const uint8_t D6   = 12;
static const uint8_t D7   = 13;
static const uint8_t D8   = 15;
static const uint8_t D9   = 3;
static const uint8_t D10  = 1;

#include "../generic/common.h"

#endif /* Pins_Arduino_h */

platformio.ini Code ：

modify VSCODE Serial port monitor baud rate , Add the code ：monitor_speed = 115200   #VSCODE Serial port monitor baud rate

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

[env:nodemcuv2]
platform = espressif8266
board = nodemcuv2
framework = arduino
monitor_speed = 115200   #VSCODE Serial port monitor baud rate 

The third step ： compile 、 download 、 function .

1） After downloading the code successfully , You can see the LED Light flashing .

2）VSCODE Open the serial port monitor , You can see the print Hello world!.
