Backlight on/off

In main.c (st2205tool/setpic/main.c), replace int main() function with following function:

int main(int argc, char **argv) {
    st2205_handle *h;
    int y;
    if (argc<2) {
	printf("Usage: %s /dev/sdX pic.png [on|off]\n",argv[0]);
	exit(0);
    }
    h=st2205_open(argv[1]);
    if (h==NULL) {
	printf("Open failed!\n");
	exit(1);
    }
    printf("Found device: %ix%i, %i bpp\n",h->width,h->height,h->bpp);

    y=sendpic(h,argv[2]);
    if (!y) {
        //p'rhaps a dir?
	DIR *dir;
	struct dirent *dp;
	char fn[2048];
	dir=opendir(argv[2]);
	if (dir==NULL) {
	    //Nope :/
	    printf("Couldn't open %s.\n",argv[2]);
	    exit(1);
	}
	while ((dp = readdir (dir)) != NULL) {
	    strcpy(fn,argv[2]);
	    strcat(fn,"/");
	    strcat(fn,dp->d_name);
	    sendpic(h,fn);
	}
    }
    if (strcmp(argv[3],"off")==0) {
	st2205_backlight(h, 0);
    } else if (strcmp(argv[3],"on")==0) {
	st2205_backlight(h, 1);
    }
    st2205_close(h);
    return(0);
}

It works great here.

I'll incorporate a similar function the next revision :) -Sprite tm
