6.2.4.5.1. mpp fb 接口使用
mpp fb 接口操作示例:
int main(void)
{
struct aicfb_screeninfo 9nfo = {0};
struct mpp_fb *fb;
int zero, ret;
mpp_fb_probe();
fb = mpp_fb_open();
if (!fb)
return -1;
// enable lcd panel
ret = mpp_fb_ioctl(fb, AICFB_POWERON, &zero);
if (ret)
return -1;
ret = mpp_fb_ioctl(fb, AICFB_GET_SCREENINFO, &info);
if (ret)
return -1;
// clear framebuffer
memset(info.framebuffer, 0x00, info.smem_len);
mpp_fb_close(fb);
return 0;
}
