OzBlackKnight Posted June 13, 2017 Share Posted June 13, 2017 Is it possible to modify the GoDMD code to suit GRB panels? The actual panels are "Leeman A SMD RGB Full Color P4 LED Display" panels with a HUB 75 interface, but are obviously not really RGB as the colours are mixed up.

There seems to be a lot of GRB panels around so it might be worthwhile having a pinout with a simple tutorial available so the less technical amongst us can fix up their panels if they receive the wrong type.

Is it just the one cable from the Shield to the one panel that needs to be done, or does the cable connecting both panels together need to be modified as well??

Content Provider lucky1 Posted August 24, 2017 Content Provider Share Posted August 24, 2017 Just the cable from the controller to the panels. I will add a configuration option for this in the next firmware release. Link to comment Share on other sites More sharing options...

That would be great - how far off is the next firmware release? Link to comment Share on other sites More sharing options...

Content Provider lucky1 Posted September 12, 2017 Content Provider Share Posted September 12, 2017 The onscreen menu is accessed by holding the menu button on the shield during boot. Link to comment Share on other sites More sharing options...
OzStick Posted September 12, 2017 Share Posted September 12, 2017 Can't do that as my Shields don't have the button on them!! Link to comment Share on other sites More sharing options...

Looks like I'll stick to modding the cable to swap the wires over. Link to comment Share on other sites More sharing options...
Rappelbox Posted September 12, 2017 Share Posted September 12, 2017 Adding 2 buttons and 2 resistors is maybe 50 cents and 10 minutes effort. Link to comment Share on other sites More sharing options...

Just to reiterate, the PIN2DMD units I make up are for use with VPin ONLY, so I'd prefer to avoid adding any non-essential components to the Shields. As a point of interest, if anything is altered via the onscreen menu then how are the settings saved? On the Discovery board? If so, then can I use a "fully featured" shield to access the onscreen menu and make changes, then once the settings are saved swap over to a "barebones" shield?

Rappelbox Posted September 13, 2017 Share Posted September 13, 2017 Yes, you could copy settings from one sd-card to another. i see buttons as essential, the reason is the menu Link to comment Share on other sites More sharing options...
Content Provider lucky1 Posted September 13, 2017 Content Provider Share Posted September 13, 2017 You could do that but he next time you update the firmware the settings stored on the discovery board might get overwritten and then without buttons the user can´t adjust the panel type. So the button are in deed essential. Link to comment Share on other sites More sharing options...
OzStick Posted September 14, 2017 Share Posted September 14, 2017 So are the settings saved on the Discovery board, or an SD-Card? Link to comment Share on other sites More sharing options...
