Hi,
I am using a simple graphics application VertexColors.c in gpu_sdk_v1.00 from freescale. It has main(), init(),render(),resize() as the function blocks. and the flow of calls is like
1.main() => init() (i.e. main() is calling init())
2.init() => resize()
3.after init(), main() => render()
and then eglSwapBuffers(egldisplay, eglsurface) is called.
And now to direct it to /dev/fb1 i assume i have to include:
int fd_fb,result;
//Applying color key
struct mxcfb_color_key color_key;
color_key.color_key = 0x0;
color_key.enable = 1;
if ((fd_fb = open("/dev/fb1", O_RDWR, 0)) < 0)
{
return 0;
}
if ( ioctl(fd_fb, MXCFB_SET_CLR_KEY, &color_key) < 0) {
printf("Error in applying Color Key\n");
}
struct mxcfb_loc_alpha loc_alpha;
ioctl(fd_fb, FBIOBLANK, FB_BLANK_NORMAL);
loc_alpha.enable = 1;
loc_alpha.alpha_in_pixel = 1;
result = ioctl(fd_fb, MXCFB_SET_LOC_ALPHA, &loc_alpha);
if (result < 0)
{
printf("fb ioctl MXCFB_SET_LOC_ALPHA fail\n");
//goto err1;
}
ioctl(fd_fb, MXCFB_WAIT_FOR_VSYNC, 0);
ioctl(fd_fb, FBIOBLANK, FB_BLANK_UNBLANK);
close(fd_fb);
Please correct me if i am wrong or if i am missing any details. But, i wonder where to include this piece of code in the given application.
Thanks in advance.
