Not sure how that is possible assuming you have a standard OSSC L336 remote, but you could try entering remote binding function by holding PCB KEY0 (near GPIO1 connector) during power-on. Also, are you sure the remote is on OSSC mode (press 'TV')? Recent versions of the remote have OSSC Pro and Framemeister keycodes programmed into DVB and HIFI slots which would be detected as valid IR codes (i.e. LED blink) but without any binding/functionality.

I'm trying to test the display lag with a 1920x1440 source.

I've reached out to @chriz2600 to see if it's possible to overclock it's FPGA, but according to the documentation, 1920x1200 is the highest it supports.

How can I lag test with the DE10-Nano and a sensor like you mentioned?

Thanks.

It wasn't a problem with the mode, it works fine on my OSSC.

It was a remote binding issue, completing a binding fixed it, I'm thinking that this is a cheap "clone" remote.

https://videogameperfection.com/forums/ ... -ir-codes/

Although, I just started putting in garbage remote codes when I couldn't figure out the key, this started at "scanline_alignm", what button is that as I want to redo the binding with the correct "later" mappings, a google on "OSSC scanline alignm" brings up nothing, is there a list of the mapping names and which button they correspond to?

Update: I found a 2nd OSSC remote in the cupboard. Question, is there an easy way to go back to the default OSSC remote codes on the de10, I'm guessing reimaging the SD will work but anything easier?

Thanks again.

At the moment documentation for many special keys is lacking. "scanline_alignm" corresponds to scanline alignment option in the menu which is explained in wiki.

You can either delete settings.bin from the SD card, or enter remote binding setup function and then press PCB KEY1 which should open a prompt to load default mappings.

In reality it'd likely work beyond that official limit, but without any guarantees on stability. The HDMI transmitter in DE10-Nano is similarly 'limited' to 165MHz (1920x1200@60), but in many case it's possible get 240MHz (2560x1440@60RB) to run just fine.

You'd need to connect a suitable sensor to one of the free GPIOs and port lag tester functionality from OSSC or create your own.

Thanks!

I can't see any rotation options, I was looking forward to that for my arcade boards?

Oh, I don't have enough knowledge to do that but maybe you can add it as a feature request or someday if the OSSC Pro is released?

Thanks for the information though!

Marqs, will the line drop function make it's way over to original OSSC?

Edit: I also am experiencing a weird issue with dexx. It’s the only HDMI Device I own that won’t play nice with my connection chain to my Sony KV-HR36M31, a HD CRT that has inputs for RGBHV and component, but no HDMI input.

Connection chain: DE10 Hdmi out > vention HDMI to VGA > five breakout cable > RGBHV inputs on the TV.

Expected outcome: TV displays the video and reproduces the audio coming from dexx, just like other HDMI devices
Actual: nothing is displayed on the TV and no sound is heard.

Troubleshooting (all give same result of no video/audio being output by display)
- try CRT mode
- try DFP mode
- try line multiplier modes
- cycle through all dexx resolution modes

Interesting findings:
- swapping dexx with OSSC 1.5 with firmware 0.90-aud. Works as expected.
- swapping vention HDMI to VGA, with Portta HDMI to comoonenet. Works as expected.

The findings point to either a) the vention has a weird dac (AG6200-MCQ - I thinks it’s a ‘Q’, the font is very difficult to read even under 10x magnification due what looks like a poor quality printing job), b) the breakout cable is weird in some way or c) there is something missing from the dexx/de10 nano signal.

If more info about the TV (it uses the AX-1 chassis) or other devices can help, let me know and I’ll find the relevant info.

It's not planned as original OSSC could only do that in very limited way, basically just 480p->480i.

Sounds like the HDMI frontend chip doesn't like the incoming signal for some reason. Perhaps worth checking if DVI mode would work.

Will do. My TV just decided yesterday to stop working so will be a while until I can test. My DIY OSSC started playing up a few days ago too so I can’t test with that either. When it rains it pours…

I'll be following this thread closely.
I’m using capture to play retro consoles on PC with RetroArch and ReShade shaders, so this device would be an instant buy. Ideally, it’d have support for component and 480p (or better, for 360 and PS3). The software side on PC would need a lot of work, but we have to start somewhere. :)

Also, can I use the 20x2 LCD (NHD-0220CW) or do I need to use the 16x2 (NHD-0216CW) ?

Has anybody designed any 3D printable cases for the DExx + DE10-Nano?

Yes, I used the "NHD-0220CW-AB3". Edit: I almost forgot that I did need to obscure the IR receiver on the DExx PCB since the wider LCD's footprint overhangs that side of the board when mounted the only way I figured I could use it; there were no problems using the remote. I may have also reversed or bent the LCD's header pin angle, but I think that would be as obvious a decision for any assembler in my "I need to use what I bought" predicament, as it was for me.

Edit 2023-07-12:Sorry this is so much later, but collectively these pictures should be worth four-thousand words:

Sorry, I didn't look for one, although it would be nice to limit my room's major dust collection. ;)

I see there was a GitHub commit yesterday, any new features in there, I'm not enough of a coder to work out what changed?

Sorry for late update. For some reason I haven't received notifications from this topic. Firmware updates from OSSC Pro are merged to DExx from time to time and changelog is posted on wiki and VGP forums. Reverse LPF and Hybrid scanlines were added in v0.67. Next update will include loadable Shadow masks (Mister format) and HDR flag toggle.

TV has been repaired, and now the dexx is displaying an image on the TV as expected. I haven't investigated whether these two events may be related, the TV repair was just replacing a couple ICs on the d board, something to do with shitty engineering of the power regulation on late-era Sony CRTs. Anyway, working as expected now so maybe just a weird issue in the TV.

ETA: found the source of the problem. My HDMI to VGA adapter can't connect to the De-10's HDMI socket properly. Problem goes away when an adapter is added between the HDMI2VGA and the de10.

Btw, line-tripled 240p on a HD CRT looks amazing. Add some scanlines via the dexx and it's as authentic of a HD retro experience as you can get imo.

Also, if there is some testing I can help with, let me know. Have the HD CRT and a flat panel available.

Can someone recommend a component over scart adapter to use with Dexx?
