How to set GPIO direction in beaglebone black in android using c code.....????
Hi,Friends,...
I'm Trying this code for set GPIO Direction For BBB in android ,compilation
completed successfully But*Output NO
Change*......
What are you expecting to change? If this is a normal GPIO pin, the direction
will be already set to 'in' when you export it.
*Code:-
void input1(int pin)
{
char buf[10];
char buf2[50] = "/sys/class/gpio/gpio";
FILE *in,*indir;
in = fopen("/sys/class/gpio/export", "w");
fseek(in,0,SEEK_SET);
fprintf(in,"%d",47);
fflush(in);
sprintf(buf,"%i",pin);
strcat(buf2,strcat(buf,"/direction"));
indir = fopen(buf2, "w");
fseek(indir,0,SEEK_SET);
fprintf(indir,"in");
fflush(indir);
fclose(in);
fclose(indir);
}
Thank you.....
*
