Hello, I'm looking for NEEK Standard System configuration (EP3C25) (like: http://www.nioswiki.com/@api/deki/files/115/=neek_ocm_spi.zip) with a VGA Controller (like: http://forum.niosforum.com/forum/index.php?act=attach&type=post&id=57) already implemented and connected. Has somebody tried this controller on NEEK ? I have problems making the connection with the top level entity. Thanks in advance D.

Some little advices would be grateful. D.

What exactly is the question ? What does work and what does not work ? What kind of Linux are <you intending to use (MMU or not) ? Did you try and of the prebuilt NEEK Linux binary distributions ? Do they work ? Did you compile a Linux-distr yourself ? Does it work ? -Michael

Hi, I have uClinux (no-MMU) running on the NEEK. I tried some prebuilds and currently running self compiled uClinux-dist without problems. As for my project I would like to run my applications and show them on a external monitor. Now I'm trying to extend the Standard System (http://www.nioswiki.com/@api/deki/files/115/=neek_ocm_spi.zip) with the VGA controller. I upgrated and generated the system with the vga controller component in SOPC Builder already. Problem: I don't exactly know how to merge the vga controller with the top level entity / assigne pins to the VGA DAC. Moreover the VGA DAC is located on the daughtercard which is connected over HSMC connector with the CIII Board. Some hinds how to do the connections would be great. Regards, D.

Hi, Are you asking the method of Pin Assignment ? Please select Menu Bar : Assignments-->Pin Planner after the compilation. Or please visit Altera site and watch online demo. http://www.altera.com/education/demonstrations/online/design-software/basic/onl-fpga-cpld-design.html Kazu

Thank you for your reply. Actually I wanted to know which pins between the vga controller and the CIII Board / HSMC connecter have to be set / are involved. As for the system, I attached a picture of bottom end of the system structure (Symbol File) - sysfile.jpg. I also attached a picture showing a part of the HSMC schematics - hsmc maxii2210.jpg. Especially I want to know how and where to place the outputs for RGB on the HSMC. Regards, D.

Thank you Kazu.

I'm going to try the "video pipeline" like the one for LCD display, but altering and adapting for the VGA. I assume this would work out for the vga part.

I also going to try the methode with the VGA controller and connecting the encoded output to the HSMC.

Hi all, I wish you a Happy New Year!

I would like to ask for help with some explanation of the VGA controller (http://forum.niosforum.com/forum/index.php?showtopic=3165) (http://forum.niosforum.com/forum/index.php?showtopic=3165%29).

I once again attached the picture which shows the bottom of block diagram of the top lvl entity - sysfile.jpg

I would like to know what the outputs m1_/m2_from_the_vga_controller mean and where do I have to place the assignments, respectively.

Furthermore I do not exactly know the difference between the output sync_n_from_the_vga_controller and sync_t_from_the_vga_controller.

Any advice would be appreciated.

Regards,
D.

Hi,

I have put the VGA controller aside due to some complications and trying the video pipeline method for controlling the external monitor.

How do I get 10-bit wide output of the VGA Data with the components which are also used to control the LCD display (8-bit output data) of the NEEK? Actually thats my problem at the moment.

I will be grateful for some advice.

D.
