Hi,
 Could I know how can I control the AC line(230V-13A)( I mean cut off and on) with the help of SSR relay and which rating relay should I use?I want to control it. I mean when I sentt signal to on, line will on, when sent off, the line will be cut off

thank you brothers....It works

It's going to loop in a microseconds and it will continue looping..but every 15 times, the data is reset to 0

ah....sry brother...I cannot understand...let's say if this is my program...How can i Stop at 15th loop(making datastore 0)?I mean I want to continue the loop but I want to reset the datastore to 0.

Code:

float KWH;
      KWH=(float) pow/1000/60;
      Serial.print("Total energy usage for 1 min=");
      Serial.println(KWH,2);
      
    
      
      datastore= datastore + KWH;
      //float finaldata=datastore+KWH;
      Serial.print("DATA=");
      Serial.println(datastore,2);

Hi everybody,
        Newbie here. How can I make to do something when the program loops 15 times.My program is I am calculating the data, when the data is 15 times runned, i want to reset to 0.

Hi everybody,
       May I know how to use the interrupt function on Arduino Uno. It's like I want to give a 15 min interrupt.

I also got it from vendor .All I do is read the data sheet and managing for the code based on the data sheet.But I'm also still on the way so we can help each other out.

@Tom BTW What's this line also...Thanks a lot

Code:

data.value = 1; //This is the default value from datasheet, just using it as an example.

@Paradigm yes,I'm on the same boat as you.   and I used Energy IC diagram as in the data sheet page 42 to join the Arduino Uno....working out on the program..

@Tom  Thanks for the correction.. How can I print the voltage?I mean when I print out,the voltage value remains at 0.Should this line be in the loop?

Code:

unsigned long voltage = SPI_read(4);//Instantaneous Voltage Channel 1

ouch...  How can I repair the Write and Read Functions?Is my Initializing part(syncing and conversion) correct?

The program is not working..but it can compile...that line is to be able to make 32 bits into 1 line

Hi everybody,
         Currently i'm now trying to get a data from my energy ic chip CS5464....but I dun know why my program is not working.Help me please..thanks a lothttp://www.cirrus.com/en/pubs/proDatasheet/CS5464_F3.pdf

Code:

#include <SPI.h>

int CS = 10;


union FourByte{
    struct {
      unsigned long value:24; //24bit register values go in here
      byte command:8; //8bit command goes in here.
    };
    byte bit8[4]; //this is just used for efficient conversion of the above into 4 bytes.
};

void setup(){
  SPI.begin();
  SPI.setBitOrder(MSBFIRST);
  SPI.setDataMode(SPI_MODE0);
 
  Serial.begin(9600);
  pinMode(CS, OUTPUT);
  digitalWrite(CS, HIGH);
  //Page
  //example of reading data
 // unsigned long voltage = SPI_read(0x04);//Instantaneous Voltage Channel 1
 
  //example of writing data
  union FourByte INI;
  INI.command = 0b11111111; //Write to config register
  INI.value = 0xFFFFFE; //This is the default value from datasheet, just using it as an example.
  SPI_write(INI);
 
 
  union FourByte data;
  data.command = 0b11101000; //Write to config register
  data.value = 0xFFFFFE; //This is the default value from datasheet, just using it as an example.
  SPI_write(data);
}

void loop(){
  unsigned long voltage = SPI_read(0x04);
  Serial.print("Voltage=");
  Serial.println(voltage);
  delay(1000);
}

void SPI_write(union FourByte data) {
  digitalWrite(CS,LOW); //Using CS pin, so sync1/sync0 bytes not needed
  for(char i = 3; i >= 0; i--){
    SPI.transfer(data.bit8); //transfer all 4 bytes of data - command first, then Big Endian transfer of the 24bit value.
  }
  digitalWrite(CS,HIGH);
}

unsigned long SPI_read(byte command){
  digitalWrite(CS,LOW); //SS goes low to mark start of transmission
  union FourByte data = {0xFEFEFE,command}; //generate the data to be sent, i.e. your command plus the Sync bytes.
  for(char i = 3; i >= 0; i--){
    data.bit8 = SPI.transfer(data.bit8); //send the data whilst reading in the result
  }
  digitalWrite(CS,HIGH); //SS goes high to mark end of transmission
  return data.value; //return the 24bit value recieved.
}

I changed to this...but still not working...

Code:

#include <SPI.h>

int CS = 10;


union FourByte{
    struct {
      unsigned long value:24; //24bit register values go in here
      byte command:8; //8bit command goes in here.
    };
    byte bit8[4]; //this is just used for efficient conversion of the above into 4 bytes.
};

void setup(){
  SPI.begin();
  SPI.setBitOrder(MSBFIRST);
  SPI.setDataMode(SPI_MODE0);
  
  Serial.begin(9600);
  pinMode(CS, OUTPUT);
  digitalWrite(CS, HIGH);
  //Page
  //example of reading data
 // unsigned long voltage = SPI_read(0x04);//Instantaneous Voltage Channel 1
  
  //example of writing data
  union FourByte INI;
  INI.command = 0b11111111; //Write to config register
  INI.value = 0xFFFFFE; //This is the default value from datasheet, just using it as an example.
  SPI_write(INI);
  
  
  union FourByte data;
  data.command = 0b11101000; //Write to config register
  data.value = 0xFFFFFE; //This is the default value from datasheet, just using it as an example.
  SPI_write(data);
}

void loop(){
  unsigned long voltage = SPI_read(0x04);
  Serial.print("Voltage=");
  Serial.println(voltage);
  delay(1000);
}

void SPI_write(union FourByte data) {
  digitalWrite(CS,LOW); //Using CS pin, so sync1/sync0 bytes not needed
  for(char i = 3; i >= 0; i--){
    SPI.transfer(data.bit8[i]); //transfer all 4 bytes of data - command first, then Big Endian transfer of the 24bit value.
  }
  digitalWrite(CS,HIGH);
}

unsigned long SPI_read(byte command){
  digitalWrite(CS,LOW); //SS goes low to mark start of transmission
  union FourByte data = {0xFEFEFE,command}; //generate the data to be sent, i.e. your command plus the Sync bytes.
  for(char i = 3; i >= 0; i--){
    data.bit8[i] = SPI.transfer(data.bit8[i]); //send the data whilst reading in the result
  }
  digitalWrite(CS,HIGH); //SS goes high to mark end of transmission
  return data.value; //return the 24bit value recieved.
