Thanks to Hans Wedermeyer. , RJ Hamlett and Tomi

I thought it appropriate although a little late now to say thanks to Hans Wedermeyer, RJ Hamlett, and Tomi whose replies to a message posted on this board steered me in the right direction to a problem that had me pulling my hair out at times.

By the way i did use the spi hardware and can receive 64 bit data at 1M/bits/s (well thats what i tested up to) using int_ssp and read_spi().

Well thanks guys.

And i'd better thanks to the likes of PCM Programmer also because his previous replies have also been helpful to me.

And sorry to everone else for taking up space on this message board with an off topic post.

Why not post an example? I'm interested in moving 16 bytes of data in both directions at the same time.

Here is my code for receiving and displaying 32 bits of data, don't know about sending. All previous code on this board was really complex compared to this, maybe people are scared to give things away, hence private reply.

Sending and recieving data at the same time? Is it possible to do that with SPI. Let me know if you can do it.

Don't know if this is of any use to you but it works fine for my application.

Let me know what you think.

int rx[4];
int i=0;


void main()
{

lcd_init();


setup_spi(SPI_SLAVE | SPI_L_to_H | SPI_SS_DISABLED);

delay_ms(100); //stabilization time for PIC


disable_interrupts ( GLOBAL );
enable_interrupts ( GLOBAL );
enable_interrupts (INT_SSP);

delay_ms(100);

do
{

if(i==3){
printf(lcd_putc,"\f a: \%x \%x \%x \%x ",rx[0], rx[1], rx[2], rx[3]);
delay_ms(1000);
lcd_putc("\f");
i=0;
}

}
while(1);
}



#INT_SSP
spi_isr()
{
rx[i]=spi_read();

i++;

}
