Hi all , 

 

Where can i read details about functions like : 

 

alt_up_pixel_buffer_open_dev(); and alt_up_pixel_buffer_draw(); etc all that relate to vga SOC in UP . 

 

I have read Altera ip Cores for DE boards , but it does not any details or examples of how to use these functions e.g  

 

CHAR_BUFFER= alt_up_char_buffer_open_dev("/dev/video_character_buffer_with_dma_0"); 

 

where can i find /dev/video_character_buffer_with_dma_0 , i dont see any dev folder in my project ???? 

 

Regards ,
