如何直接写入linux framebuffer?
看看FBIOPUT_VSCREENINFO,ioctl和mmap
(我有代码,但没有此电脑,对不起)
编辑:这应该让您开始
//open file descriptor and get info inf fdScreen = open( "devicename", O_RDWR ); fb_var_screeninfo varInfo; ioctl( fdScreen, FBIOGET_VSCREENINFO, &varInfo ); //set resolution/dpi/color depth/.. in varInfo, then write it back ioctl( fdScreen, FBIOPUT_VSCREENINFO, &varInfo ); //get writable screen memory; unsigned short here for 16bit color unsigned short* display = mmap( 0, nScreenSize, PROT_READ | PROT_WRITE, MAP_SHARED, fdScreen, 0 );
