Dear Justin Schoeman and all:
Thanks to Justin, I have some ideas of writing I2C for
my card. I've wrote a program just to open the i2c,
but the program didn't successfully go thru. The
following is my program:
//
#include <fcntl.h>
#include <stdio.h>
#include <linux/i2c.h>
#include <linux/i2c-dev.h>
int main()
{
int file;
printf("Opening device...\n");
if ((file = open("/dev/i2c-0",O_RDWR)) < 0)
{
printf("\nError:%d\n", file);
perror("open() failed");
}
printf("Done\n");
close(file);
}
//
The error message is like:
Opening device...
Error:-1
open() failed: No such device
Done
//
I already "cat" the bus and it said:
i2c-0 i2c bt848 #0 Bit-shift
algorithm
Does anyone know what I should do to fix it? My PCI
card is there, and a bt878 is on there. Thanks!!!
