Nodemcu-esp8266 development (vscode+platformio+arduino framework): Part 2 --blinker_ Hello_ WiFi (lighting technology - Mobile App control routine)

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

Secondly, complete the establishment of the project template ：https://blog.csdn.net/felix_tao/article/details/113282760

First step ： A copy of template engineering , And rename to Blinker_Hello_WiFi.

The second step ： open VSCODE-> file -> Add folder to workspace -> Select the project folder Blinker_Hello_WiFi-> Add to VSCODE in .

The third step ： Download lighting technology blinker Arduino library , And copy it to platformio arduino esp8266 Under the Library Directory of .

1） Open the url https://www.diandeng.tech/doc/getting-start-8266, find “ Download and install blinker Arduino library ”, Click download .

2） decompression blinker-library-master.zip after , Copy blinker-library-master To directory C:\Users\felix\.platformio\packages\framework-arduinoespressif8266\libraries Next .

Step four ： Copy Hello_WiFi The code in the routine goes to VSCODE Medium src->main.cpp Inside .

1） Open Directory C:\Users\felix\.platformio\packages\framework-arduinoespressif8266\libraries\blinker-library-master\examples\Blinker_Hello\Hello_WiFi.

2） use NotePad++ open Hello_WiFi.ino, Copy the code inside to src->main.cpp Inside ( All the original codes are deleted ).

3） Discovery tips #include <Blinker.h> Not included , close VSCODE, Open it again , I found that just now “ Prompt not included ” Vanished , This is because reopening VSCODE after , In the project .vscode->c_cpp_properties.json It automatically loads the header file containing , namely "C:/Users/felix/.platformio/packages/framework-arduinoespressif8266/libraries/blinker-library-master/src".

4） So you can adjust the order of the above steps , First copy the library file blinker-library-master, Reuse VSCODE Open the project , There is no need to close VSCODE Reopen , No matter what , remember ：.vscode->c_cpp_properties.json There is no need to make any changes to the documents inside , The software will automatically help us complete the addition of header files .

5）Hello_WiFi The routine code is as follows ：

#define BLINKER_WIFI

#include <Blinker.h>

char auth[] = "Your Device Secret Key";
char ssid[] = "Your WiFi network SSID or name";
char pswd[] = "Your WiFi network WPA password or WEP key";

//  New component object 
BlinkerButton Button1("btn-abc");
BlinkerNumber Number1("num-abc");

int counter = 0;

//  Press the key to execute the function 
void button1_callback(const String & state)
{
    BLINKER_LOG("get button state: ", state);
    digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
}

//  If unbound components are triggered , Then the content will be executed 
void dataRead(const String & data)
{
    BLINKER_LOG("Blinker readString: ", data);
    counter++;
    Number1.print(counter);
}

void setup()
{
    //  Initialize serial port 
    Serial.begin(115200);
    BLINKER_DEBUG.stream(Serial);
    BLINKER_DEBUG.debugAll();
    
    //  Initialization has LED Of IO
    pinMode(LED_BUILTIN, OUTPUT);
    digitalWrite(LED_BUILTIN, HIGH);
    //  initialization blinker
    Blinker.begin(auth, ssid, pswd);
    Blinker.attachData(dataRead);

    Button1.attach(button1_callback);
}

void loop() {
    Blinker.run();
}

Step five ： stay app Add devices to , obtain Secret Key.

1） download APP And install , Open the url https://www.diandeng.tech/doc/getting-start-8266, find “ Download and install blinker APP“, According to different mobile platforms , Download the corresponding APP And install .

2） Get into App, Click on the “+” Number , And then choose   Add equipment .

3） Click Select Arduino（ Independent equipment ）-> WiFi Access .

4） Select the service provider you want to access （ Alibaba cloud 、 Lighting technology 、 Tencent cloud 、OneNet）, Choose here ” Alibaba cloud “, It's mainly to connect with Xiao AI in the future ,“ Lighting technology ” I don't support Xiao AI .

5） Copy the application to Secret Key Go to the key column in the code .

Step six ： Modify the following code .

1） Modify the key 、wifi name 、wifi The password is your own .

char auth[] = "Your Device Secret Key";//Blinker APP Obtained in Secret Key( secret key )
char ssid[] = "Your WiFi network SSID or name";//wifi name 
char pswd[] = "Your WiFi network WPA password or WEP key";//wifi password 

2） Modifying initialization LED Default level .

//digitalWrite(LED_BUILTIN, HIGH);
digitalWrite(LED_BUILTIN, LOW);// Default on LED

3） The modified and sorted code is as follows ：

/* *****************************************************************  
 *  Program function ：
 * 1. Use the development board ：nodemcu-ESP8266( modular ESP-12E)
 * 2. Program function ： Use Blinker  mobile phone APP Add devices and bind , adopt APP Remote control the light on the development board 
 * 3. Routine documentation ：https://www.diandeng.tech/doc/getting-start-8266
 * *****************************************************************/

//#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 

#define BLINKER_WIFI
#define BLINKER_WITHOUT_SSL  //blinker By default, encryption is used for remote communication , But communication encryption will consume a lot of RAM, If you have no requirements for communication security ,
							 // You can add macros BLINKER_WITHOUT_SSL To get more available RAM,BLINKER_WITHOUT_SSL At present, it can only be used for ESP8266, Other devices RAM Enough for encrypted communication 

#include <Blinker.h>         // Using third party libraries 

char auth[] = "a3c936aa1b16";//Blinker APP Obtained in Secret Key( secret key )
char ssid[] = "Xiaomi_123";  //wifi name 
char pswd[] = "felix1234";   //wifi password 

//  New component object 
BlinkerButton Button1("btn-abc");// Component object , Want to be with APP In the component “ Data key name ” Agreement 
BlinkerNumber Number1("num-abc");

int counter = 0;// Counter 

//  Press the key to execute the function 
void button1_callback(const String & state)
{
    BLINKER_LOG("get button state: ", state);//APP Medium Monitor Control print information 
    digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));// control LED The light is on and off , Low level light , High level off 
}

//  If unbound components are triggered , Then the content will be executed 
void dataRead(const String & data)
{
    BLINKER_LOG("Blinker readString: ", data);
    counter++;
    Number1.print(counter);
}

void setup()
{
    //  Initialize serial port 
    Serial.begin(115200);
    BLINKER_DEBUG.stream(Serial);
    BLINKER_DEBUG.debugAll();
    
    //  Initialization has LED Of IO
    pinMode(LED_BUILTIN, OUTPUT);
    //digitalWrite(LED_BUILTIN, HIGH);
    digitalWrite(LED_BUILTIN, LOW);// Default on LED

    //  initialization blinker
    Blinker.begin(auth, ssid, pswd);
    Blinker.attachData(dataRead);

    Button1.attach(button1_callback);// Bind key callback 
}

void loop() {
    Blinker.run();
}

Step seven ： After modification , Compile 、 download , During the compilation process, we found that “ Yellow warning ”, Don't mind , The final compilation is “SUCCESS” Just OK.

After downloading successfully , You can see the LED It lights up , open VSCODE The serial monitor can see and print some information .

Step eight ： Using mobile phone APP Carry out remote control in the development board LED The lamp .

1） open APP, Due to unpaid , So I entered APP The interface is DIY Interface .

2） On the device list page , Click on the device icon , Enter the device control panel .

3） Enter the device control panel for the first time , The wizard page will pop up .

4） On the wizard page, click   Load examples , You can load the sample assembly .

5） Make sure the device is online , And then click ” Light me on ” You can control LED Light on and off .

6） because “ Let me count ” Unbound in code , So it triggers dataRead（） function .

thus , All processes are completed , Have fun ！
