Unable to implement SPI communication using mikroc library

[umair]

I want to implement spi protocol between two pic18f4550 using mikroc library but cant? I am sending data from master to slave and displaying both controller output on uart. Please help me in removing error in my code…

Here is my code

MASTER CODE:

/*MASTER CODE*/

     sbit chipselect at RD0_bit;

     sbit chipselect_Direction at TRISD0_bit;

     sbit SDO at RC7_bit;

    sbit SDO_Direction at TRISC7_bit;

    sbit SDI at RB0_bit;

    sbit SDI_Direction at TRISB0_bit;

    sbit SCK at RB1_bit;

    sbit SCK_Direction at TRISB1_bit;

 

 

char senddata1='1';

char senddata2='2';

char senddata3='3';

char senddata4='4';

char senddata5='5';

 

 

void main() {

     ADCON0 = 0x3C; // Disabling the ADC module which is multiplexed with SPI pins

     ADCON1 = 0x0F; // Disabling the ADC module which is multiplexed with SPI pins

     CMCON = 0x00; // Disabling the COMPARATOR module which is multiplexed with SPI pins

     SPPCON = 0x00; // Disabling the SERIAL PERIPHERAL CONTROL module which is multiplexed with SPI pins

     chipselect_Direction=0;

     SDI_Direction=1;

     SDO_Direction=0;

     SCK_Direction=0;

     chipselect=0;

 

     UART1_Init(9600);

     delay_ms(100);

     SPI1_Init();

     delay_ms(100);

     do{

     SPI1_Write(senddata1);

     UART1_Write(senddata1);

     delay_ms(1000);

     SPI1_Write(senddata2);

     UART1_Write(senddata2);

     delay_ms(1000);

     SPI1_Write(senddata3);

     UART1_Write(senddata3);

     delay_ms(1000);

     SPI1_Write(senddata4);

     UART1_Write(senddata4);

     delay_ms(1000);

     SPI1_Write(senddata5);

     UART1_Write(senddata5);

     delay_ms(1000);

     }while(1);

 

 

}

 

SLAVE CODE:

/*SLAVE CODE*/

 

sbit chipselect at RA5_bit;

sbit chipselect_Direction at TRISA5_bit;

sbit SDO at RC7_bit;

sbit SDO_Direction at TRISC7_bit;

sbit SDI at RB0_bit;

sbit SDI_Direction at TRISB0_bit;

sbit SCK at RB1_bit;

sbit SCK_Direction at TRISB1_bit;

 

short readdata;

short readdata1;

 

void main() {

     ADCON0 = 0x3C; // Disabling the ADC module which is multiplexed with SPI pins

     ADCON1 = 0x0F; // Disabling the ADC module which is multiplexed with SPI pins

     CMCON = 0x00; // Disabling the COMPARATOR module which is multiplexed with SPI pins

     SPPCON = 0x00; // Disabling the SERIAL PERIPHERAL CONTROL module which is multiplexed with SPI pins

     chipselect_Direction=1;

     //SDI_Direction=1;

     //SDO_Direction=0;

     //SCK_Direction=1;

     UART1_Init(9600);

     delay_ms(200);

     SPI1_Init();

     delay_ms(100);

     do{

     readdata1=SPI1_Read(readdata);

     UART1_Write_Text(readdata1);

     readdata1=SPI1_Read(readdata);

     UART1_Write(readdata1);

     readdata1=SPI1_Read(readdata);

     UART1_Write(readdata1);

     readdata1=SPI1_Read(readdata);

     UART1_Write(readdata1);

     readdata1=SPI1_Read(readdata);

     UART1_Write(readdata1);

     }while(1);

 

}

Please help me
