Re: How to start using ADE7758

Hi hmani,

I like to know how make the communication between PIC18f2550 and ADE7758. On page 17 of the datasheet has a basic circuit of protection. I use the pins: 2, 3, 4, 11, 12, 13, 18, 19, 20, 21, 22, 23 and 24 to start communication SPI. This is correct?

My code:

function in file comunication.h:

unsigned char packetSetRegisterRead(unsigned char address){

  //Configurando pacote

  unsigned char packet = 0x00;

  packet = address;

  packet &= 0b01111111;

  //Enviando o pacote

  return WriteSPI(packet);

}

#include <comunication.h>

#define slave1 PORTAbits.RA5

void main()

//My information

          unsigned char infoEnableComunication = COMPMODE; //MODE;

//Reception date

          unsigned char dado = 0x00;

          //Set the slave

          TRISAbits.TRISA5 = 0; //Pin Slave - output

          //Set of the sck, sdi and sdo

          TRISBbits.TRISB1 = 0; //SCK

          TRISBbits.TRISB0 = 1; //SDI

          TRISCbits.TRISC7 = 0; //SDO

          TRISAbits.TRISA2 = 1; //IRQ

          //Set SPI

     OpenSPI(SPI_FOSC_16, MODE_00, SMPEND); //Open SPI

          //disable the slave

          slave1 = 1;

while(1){

     //Slave enable

     slave1 = 0;

     packetSetRegisterRead(infoEnableComunication);

     slave1 = 1;

      slave1 = 0;

      Delay10KTCYx(50);

      if (DataRdySPI()) dado = ReadSPI();

      slave1 = 1;

     }

}

What is the problem in my code?
