Greetings guys,
I am trying to compile a pretty simple program that supposedly will
flash some of the EVM's LEDS (Basic I2C interfacing).
When I try to compile this on either the EMV or via the crosscompiler on
my host machine I get a several screenfuls of complaints.
I have checked my installation of MV, and ensured that the path is
correct in my .bashrc file. Is there anything else I need check before
trying a reinstall?
Regards,
Andrew

int i2cfile;

return -1;
}
if (ioctl(i2cfile, I2C_SLAVE, i2c) < 0)
{
perror(__FUNCTION__);
fprintf(stderr, "error setting address %i\n", errno);
close(i2cfile);
return -1;
}
buf[0]=a;
buf[1]=d;
ret=write(i2cfile, buf, 2);
close(i2cfile);
return 0;
}
int main(void)
{
write_i2c(0x38, 0,0xAA);
}
