使用Linkit 7697打造遠端遙控智能燈座 - Part 2

這次手作了35 PCS課堂上使用，包括11月Maker Faire Taipei展覽樣品

和鎢絲燈泡一起打包過後，就像準備出貨，只是難看了點

工作桌凌亂不堪，但為了就是要學員一次就上手!

且準備了九支程式、電路圖說明與Layout走線，要在三小時完全學會

而且當天會有小鮮肉助教，把教材給他之後，我就可以喝飲料看漫畫了

希望之後完整系列課程結束，能讓大家多多關心自己家中的長輩 ^ ^

先前寫了一篇使用Linkit 7697打造遠端遙控智能燈座，這一篇是Part 2

以下程式可以按下d、a、b調光

操作影片在這

int pinLed = 14;

int PWM = 9; // PWM pin

int dimming = 40;  // Dimming level (0-128)  0 = ON, 128 = OFF

int flag1=0,flag2=0,flag3=0;

void setup(){

    Serial.begin(9600);

    pinMode(2, INPUT);

    pinMode(pinLed, OUTPUT);

    analogWrite(PWM, 55);  //setting PWM speed

    Serial.println("Hello");

}

void loop(){

   int switchStatus = digitalRead(2);

    String s = "";

 

    while (Serial.available()) {

    char c = (char) Serial.read();

        if(c!='\n')

        {

            s += c;

        }

        delay(1); 

    }

    if(s=="d"){

    flag1=1;

    flag2=0;

    flag3=0;

    dimming=40;

    Serial.println(s);

 }

    if(s=="a"){

     flag2=1;

     flag1=0;

     flag3=0;

     dimming=30;

     Serial.println(s);

 }

 if(s=="b"){

     flag3=1;

     flag2=0;

     flag1=0;

     Serial.println(s);

 }

   if(switchStatus==HIGH && flag1==1)

  {

   

   Serial.println("ddd");

  int dimtime = (65*dimming);    // For 60Hz =>65   

  delayMicroseconds(dimtime);    // Wait till firing the TRIAC   

  digitalWrite(pinLed , HIGH);   // Fire the TRIAC

  delayMicroseconds(8.33);         // triac On propogation delay

         // (for 60Hz use 8.33) Some Triacs need a longer period

  digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

     }

     if(switchStatus==HIGH && flag2==1)

  {

   

  Serial.println("aaa");

  int dimtime = (65*dimming);    // For 60Hz =>65   

  delayMicroseconds(dimtime);    // Wait till firing the TRIAC   

  digitalWrite(pinLed , HIGH);   // Fire the TRIAC

  delayMicroseconds(8.33);         // triac On propogation delay

         // (for 60Hz use 8.33) Some Triacs need a longer period

  digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

  }

  if(switchStatus==HIGH && flag3==1)

  {

   

  Serial.println("bbb");

  digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

  }

}

以下程式可做出AC呼吸燈泡模式

將%Localappdata%\Arduino15\packages\LinkIt\hardware\linkit_rtos\0.8.4\cores\arduino\wiring_interrupt.c

裡面的eint_config.debounce_time = 50; // debounce time unit: ms

50改為0

-->可以在C槽中找

操作影片在這

int pinLed = 14; //output pin

int flag = 0;

int dimming = 128;  // Dimming level (0-128)  0 = ON, 128 = OFF

int brightness = 40;    // how bright the LED is

int fadeAmount = 1;    // how many points to fade the LED by

void setup()

{

 pinMode(pinLed, OUTPUT);

 attachInterrupt(2, interrupt, RISING); //using interrupt

 Serial.begin(9600);

}

void loop()

{

if (flag == 1 )

{

// change the brightness for next time through the loop:

 brightness = brightness + fadeAmount;

 dimming=brightness;

 Serial.println(brightness);

 int dimtime = (65*dimming);    // For 60Hz =>65   

  delayMicroseconds(dimtime);    // Wait till firing the TRIAC   

  digitalWrite(pinLed, HIGH);   // Fire the TRIAC

  delayMicroseconds(8.33);         // triac On propogation delay

         // (for 60Hz use 8.33) Some Triacs need a longer period

  digitalWrite(pinLed, LOW);    // No longer trigger the TRIAC (the next zero crossing will swith it off) TRIAC

      // reverse the direction of the fading at the ends of the fade:

  if (brightness <= 10 || brightness >= 100)

  {

    fadeAmount = -fadeAmount;

  }

   flag = 0;

  }

}

void interrupt()

{

 flag = 1;

}

這次是初階課程，如果控制30顆燈泡同時閃爍或亮滅，會挺壯觀

但可惜的是，MQTT要等到進階課程才會教到  ^ ^
