DE0-Nano and DE2-115 add-on boards for Prop2 emulation are ready!

Yes, that's how we jump back to Chip's monitor

Thinking about what I can do with one cog...

Can coginit work on the cog calling it?

Cute DE2 board. Did you post a schematic?

Are the board interconnects Mictor (expensive)?

Thanks a ton Chip.

Schematics were posted some time ago.

ctwardell · 2013-03-08 06:39

Do we need updated software for the add-on boards?

Thanks,

C.W.

EDIT: Mine came today, really nice board.

@ C.W.,
Chip posted an updated DE0 firmware here

There will hopefully be one for the DE2 soon too

Most Excellent, Thanks!

You guys are welcome!

See if you can run these video demos:

simple_HDTV_1920x1080p.spin
simple_HDTV_1280x720p.spin
simple_NTSC_256x192.spin
simple_VGA_1280x1024.spin
simple_VGA_800x600.spin
simple_VGA_640x480.spin

Sapieha · 2013-03-08 13:04

Hi Chip.

On simple_VGA --- Have You even 800x600 and 640x480 ? config values

Hi Chip,

I programmed a Nano, and PNUT detects rev 32

BUT

I cannot get into the monitor

I hit space, enter, and nothing.

Any ideas?

Update:

Sapieha told me I have to strap pins 3-5 on the 26 pin connector; trying that now...

Remove the 8-pin flash chip. It has a program in it that just toggles some pins.

nutson · 2013-03-08 13:53

DE0-nano enters monitor o.k. after removing the flash chip. Thanks

Bill Henning · 2013-03-08 13:55

Thanks, that worked!

(DUH, I should have thought of pulling the flash chip...)

Demo VGA 1280x1024 works fine on DE0-nano. Start trying the DE2-115 now.

Sapieha · 2013-03-08 14:10

Hi Chip.

Why not use that 2 IO's to on-board PS2 instead on DE2-115

P42 no connection on DE0-Nano, LED10/SW10 on DE2-115
P43 no connection on DE0-Nano, LED11/SW11 on DE2-115

It took me a while to figure that out, too.

ctwardell · 2013-03-08 14:20

Removed the FLASH chip and all is well with my Nano.

The VGA demo works well.

Sapieha · 2013-03-08 14:25

Hi.

I don't have spare monitor that can use that 1080p

only one that can show 1024x768 and one 800x600

Have my DE2-115 configured and the VGA 1024x1280 demo running! Great work, thanks.

I don't have a TV in the office, but tried the NTSC demo with my el-cheapo Ulead USB video capture device and it works pretty well.

SIGMAC 15" 720p TVI

- 1280x1024 vga comes up as "unsupported mode" i.e. the SIGMAC does not like the timing
- 720p component video not tested yet
- 1080p component video not tested as it is a 720p TV
- NTSC video not tested yet

INSIGNIA 24" 1080p TV

- 640x480 vga now works, use 60Hz VESA mode with FREQA set as below
- 800x600 vga now works, use 60Hz VESA mode with FREQA set as below
- 1024x768 vga works, use 60Hz VESA mode with FREQA set as below
- 1280x1024 vga now works, use 60Hz VESA mode with FREQA set as below
- 1280x720 vga works, use 60Hz VESA mode with FREQA set as below
- 1920x1080 vga works, use 60Hz VESA mode with FREQA set as below
- 480p component video works, but there is some "dot crawl" on the vertical divisions between color bands
- 720p component video works, but there is some "dot crawl" on the vertical divisions between color bands
- 1080p component video works, but there is some "dot crawl" on the vertical divisions between color bands
- NTSC video works if "Auto Input Detect" is turned off, or component cable is not attached to Yr Yb

Video input works by just moving the Y cable to DAC0

FYI, the 24" TV does not document that it supports 1080p over component video, but it works just fine :-)

ViewSonic 1440x900 19" LCD VGA monitor (VA192wb)

- VGA 1280x1024 works, reports 104MHz dot clock / 58KHz HSync / 58Hz VSync
- VGA 800x600 mostly works, shows 8 bars, right 1/3 of screen black, reports 44Mhz dot clock / 43KHz VSync / 68Hz HSync
- VGA 640x480 works, shows 8 bars, right 1/5th screen black, reports 29MHz dot clock / 38KH VSync / 71Hz HSync

- 640x480 vga now works, use 60Hz VESA mode with FREQA set as below
- 800x600 vga now works, use 60Hz VESA mode with FREQA set as below
- 1024x768 vga works, use 60Hz VESA mode with FREQA set as below
- 1280x1024 vga now works, use 60Hz VESA mode with FREQA set as below

Here are the working FREQA values for modes at 60Hz VSync VESA modes:

640x480 use $0D80_0000
800x600 use $1510_0000
1024x768 use $22AA_0000
1280x1024 use $3A00_0000

I am guessing it has a really narrow range of horizontal sync timing that it accepts; I ran into this issue when writing drivers for Morpheus, with other monitors.

Good multisycns will display almost anything... cheap TV's not so much.

I am looking for documentation for what modes it will accept right now.

I could not find the documentation :-(

I wonder what the trouble is. All those signals are created to spec with accurate timing. There should be no magic about it.

Thanks!

Works on the 24" Insignia, some dot crawl every 8 scan lines or so

Here's a VGA 640x480 demo. Note that because there are minimal significant bits in the FRQA value, there is no dot crawl.

Bill Henning · 2013-03-08 18:02

Just tried the 640x480 and 800x600 .. neither worked on the 24" Insignia.

I'll try an Acer 19" multisync...
