pixel buffer vga in de2-115

hello, can anybody tell me how to send pixels to vga monitor. my code is:

alt_up_video_dma_dev* video;

for (i=0;i<rows,i++)

{

for (j=0;j<cols,j++)

{

color=(((img_R[i][j] >>8 ) & 0x0000F800)+ ((img_G[i][j] >>5 ) & 0x000007E0)(((img_B[i][j] >>3 ) & 0x0000001F));

alt_up_video_dma_draw(video,i,j,0);

}

}

the quality of the image displayed on the monitor is very bad, any clue?

    Hello rkaib

    Thank you for posting in the Intel Community.

    · What is the brand and model of your system?

    · Do you have all the updates provided by the Original Equipment Manufacturer (OEM) installed on the system?

    · What operating system do you have installed?

    Hope this helps.

      hello leonardo,

      I am almost done, my issue now is just how to read a custom IP core output data in eclipse (I have created an IPcore, included it in my design in quartus platform designer , added it in the verilog code with its connections)

      my problem now is how to detect it while in eclipse (I have looked into system.h file but it does not appear and I do not know how to retrieve its data in my c code). I am using DE2-115 board with quartus 18.1

      I hope I have been clear

      thanks.
