DExx-vd_isl remote Logitech Harmony

[Laurent]

Hello,

I am trying to make the DExx-vd_isl board working with a Logitech Harmony One+ remote.

I followed the tutorial for OSSC:
https://junkerhq.net/xrgb/index.php?title=Logitech_Harmony_and_OSSC

The green LED on the DE10nano is blinking when using the remote control, but most of the buttons are not assigned.

On the DExx-vd_isl board there is no BTN1 to enter the remote configuration, is there a way to it?

Maybe it is possible to use a USB keyboard instead?

Thanks for your help.

On DE10-Nano you need to hold down KEY0 (small tactile switch near GPIO1) instead during boot.

Thank you, it works!

Now I can use my N64 PAL RGB moded on my LG BX OLED TV 🙂

I just tried Mario, but it seems to be unstable : TV seems to resync randomly, some time I completely lost the signal and need to reboot everything.

I saw the PAL profiles for OSSC, can you load them on the DExx?

Did you use default adaptive LM mode or scaler? You might want to check this post which describes a small HW modification that can improve stability.

The included N64 presets are for NTSC, and it’s not possible to load OSSC profiles. It should be still easy to tune the existing preset for PAL if you know the correct sampling rate.

Thank you very much for your reply.
I tried the LM Pure/adaptative and Scaler, all of them are unstable.
I have done some testing, it seems that setting “Analog sync Vth” to 60mV (default:120) resolve the sync issue, so far Super Mario 64 is stable 🙂
Maybe I will do the soldering if it can improve the stability even further.

Do you have any advices to get more accurate colors? I lowered the settings “R/G/B gains” to 200 (default:324) but maybe it can be better.

Which RGB mod is installed on the machine? Sounds like there might be an issue with that if the colors are not accurate or sync stable with default settings.

I have a PAL FRA N64 with “official” RGB mod (missing CMS components soldered under the mainboard).
The problem may not come from the RGB mod but the PAL GameCube RGB cable I am using, which include some capacitors.

After trying all the settings, the best PQ I have obtained is with Scaler mode and “SL sharp” algorithm (resolution 1920×1440).
I think the picture is better than all the other scaling algorithms with post processing scan line enabled.
Thank you again for your help!
