Device Connection - Open port succeeds, but device can not connect

Herbert — Wed, 03 Feb 2010 12:08:33 +0000

Hello,

I use the Software "OptimusMiniUsageSample" to connect to the OptimusMiniThree device.

When I run the SW, sometimes the device can not be connected.
But, the condtion
if( gle == ERROR_SUCCESS && m_objPort.Open( (LPSTR)szValueData ) )
in function COptimusMini::Open() succeeds.

Question:
Why does it happen that the port is opened, but the device can not connect?

Device Driver:
OptimusMiniConfInstaller.msi, date: 2009-04-28

Thanks in advance,
Herbert

More than one Mini3 on the same computer

kent1 — Fri, 08 Aug 2008 10:27:17 +0000

Hi everybody,

I was wondering if we could plug and manage more than one Optimus Mini 3 keyboard on the same PC?
I have not seen any clue about this question in the samples code or in the doc.

If not, is this feature planned in a near future?

Thanks,

Quentin

Are there any plans of finishing this past the beta version. It seems like development is stagnant.

Detecting when OM3 button released?

abirkill — Sun, 16 Mar 2008 20:06:18 +0000

Hey guys,

Is there any way of detecting when a button is released on the OM3? Currently I'm just waiting until I get no more 'button pressed' data packets, but that causes some lag (I'm having to wait ~80ms, as when all three buttons are held down that's the typical delay between individual button update messages).

Anyone figured out a neat way around this?

Cheers!

OMC Improvements/Suggestions thread

eburnett — Thu, 29 Nov 2007 19:14:46 +0000

A thread started to spearhead potential new ideas for the almighty OMC.. all praise the OMC.

To start it off:

It would be nice to allow each modifier "set" in a given layout the ability to rotate automatically before the user's eyes. ie: by default a layout would remain "static" and wait for modifier key-presses to change sets, but introducing an option so that by pressing a certain key the OM3 would stop/start a cycle through that layout's sets at a determined interval in seconds.

In the GUI it could be as minimal as a checkbox enabling/disabling cycling of modifier sets, with a textfield allowing the user to specify the pause time in seconds and the keyboard key to initiate the cycling.

Thoughts?

Any luck with the Widget API?

Plugin Improvements/Suggestions thread

eburnett — Thu, 29 Nov 2007 19:05:29 +0000

Apologies in advance if the admins here would rather not have such a focused thread.. but the more ideas get exposed the more likely it is we'll see them actually introduced, so.

To start it off:

G-mail notifier - would be nice if one could choose "do nothing" under the On button press preference, for security reasons (someone walking by when I'm not there, etc)

Informer - would be nice if one could specify a shorter duration than 1 min for reloading the URL. ie: a textfield allowing one to specify the Update time in seconds.

Thoughts?

Request: Widgets API

eburnett — Thu, 29 Nov 2007 18:53:36 +0000

Forgive me if it's already been released but I haven't seen any discussion about it since user Biseptol mentioned he'd be releasing it back in May '07.

As a new owner of 2 OM3's I feel the only way we'll start seeing rapid plugin development for a product like this is if JS/CSS/HTML-based plugins can be created easily.

Support for SVG under IE

stevew — Wed, 28 Nov 2007 03:11:28 +0000

Has anyone been able to display a web page that is SVG?
We have an application that shows tabular information via JSP and
HTML which works fine and can be displayed on OptimusMiniThree.
We have another application that requires scalable graphics so
we use dynamically generated SVG. All that is visible on
both the LCD and the configurator is the IE header but no content.
Thanks, Steve

Re: Gamma correction?

Death9 — Mon, 15 Oct 2007 22:32:50 +0000

Yes I see what you mean now about how bright it is!
But have a look at the attached bmp.
If you display this on the PC you can see that it's set up correctly for a 565 display and that the gradient at the bottom from dark red to red-white is smooth.
Now, if you display this on the mini3 you can see a point when red turns into white and the gradient is broken.
Turning the gamma correction off brings the gradient back correct but now its too bright (that's why the gamma is there). So, what can be done?

Thanks,
Death9

Re: Gamma correction?

Death9 — Thu, 11 Oct 2007 21:33:31 +0000

Hi MoKo,

No, I'm not working with the MiniLib but I will give it a try and see if I can reproduce my problem (then fix it).

I have put the formula for the gamma and colour temperature into my PC program and the colours all come out looking fine.
I can only guess that the OLED has an odd colour curve or something else is going on in the configurator.

I shall also put the image I'm having trouble with on my site (when I get time) so you can see what I mean.

Thanks for your support,
Death9

Re: Gamma correction?

MoKo — Thu, 11 Oct 2007 08:38:57 +0000

if you are working with OptimusMiniLibrary, you can disable them both in OptimusMini.h.

// Enables gamma correction support with default gamma set to 0,65
#define FEATURE_GAMMA
// Enables color temperature correction support with default temperature set to 8500
#define FEATURE_COLOR_TEMPERATURE

But I think you overestimated OLED color reproduction capabities. Even the darkest color (1 red 1 blue 1 green) is very bright on OLED, thus it's difficult to get a high quaility gradient, especially at dark part.

Gamma correction?

Death9 — Wed, 10 Oct 2007 22:50:45 +0000

Hi all.
So the screen is 16bit 565 format. I have some gradients in red (dark red to white) that look awful. They start to band heavily towards the white part and then look like they over saturate. I've converted my image to 565 format and put some dither on but it still looks bad. I understand that there is a white balance and gamma correction post process to the screen, perhaps these are causing my problem. Does anyone have any ideas or thoughts on the subject?

Thanks,
Death9

OptimusVIEW Toolkit for LabVIEW

gmiles — Thu, 13 Sep 2007 18:32:02 +0000

INVENTEERING is developing a LabVIEW Toolkit to work with the Optimus mini three keyboard.

Re: Brightness Question?

MoKo — Tue, 04 Sep 2007 15:34:43 +0000

Yes, it's described at OptimusMiniProtocol.doc.
It might change in future releases, but's true for all existing versions.

Re: Show OLED refresh

MoKo — Tue, 04 Sep 2007 15:31:14 +0000

Yes, please look at OptimusMiniHelper.h / OptimusMiniHelper.cpp for FEATURE_PING

// Enables device "ping" every second. If the device receive nothing in about 12 seconds,
// it turns displays off, which is useful after reset or if software terminated abnormally.

Show OLED refresh

gmiles — Tue, 04 Sep 2007 08:28:31 +0000

I have also noticed that it seems that I need to set a Show OLED # at least once every 10 seconds to keep the screens on. I use "Show OLED 0" to keep the screens on. I assume this is sort of a watchdog to turn of the screens if the program looses contact with the OM3. Is this true or is there another way to keep the screens on?

Brightness Question?

gmiles — Tue, 04 Sep 2007 08:22:14 +0000

It appears that only the valuse 20,40,60 affect the brightness. Is this true and is it going to stay this way in the future?

Re: 3 key driver is realy SideShow driver ?

Jim — Mon, 03 Sep 2007 01:05:41 +0000

Hi MoKo,
i wanted to send byte to my device support the SideShow.I consulted the OM3SideShowBasicDriverSources code that download from the web.
I used SetupDiGetClassDevs,SetupDiEnumDeviceInterfaces and others API to get the device handle in the DeviceDisplayInitialization code, but can success.
You used g_OM.Init() to get the device handle and send byte to the device in the DeviceDisplayInitialization code,why are you can success ?
Thanks!
Jim

still unclear

"First try our compiled binary SideShow driver, and if it also does not work, report."

Does Configurator work?
Does our compiled binary SideShow driver work?

Please, use Windows Vista and Windows Server Longhorn x86 Checked Build Environment.

Or fix this paranoid warnings. ^___^

MoKo — Mon, 20 Aug 2007 08:52:08 +0000

Prolific driver is also included in Configurator software installation package.
If OM3 works with Configurator, that means Prolific driver is installed correclty.
Thus SideShow driver also should work (don't forget to exit configurator before installing it).
First try our compiled binary SideShow driver, and if it also does not work, report.

Re: 3 key driver is realy SideShow driver ?

Jim — Tue, 14 Aug 2007 03:19:06 +0000

Hi Pretender,

i download the prolific driver from http://optimus.freshsite.de/read.php?24,106.
I download the OptimusMiniConfInstaller.msi from http://www.artlebedev.com/everything/optimus-mini/downloads/ .

The configurator software can work,but i do not think the prolific driver have function.
The configurator software can work as same if i don't install the prolific driver .

Re: 3 key driver is realy SideShow driver ?

Pretender — Mon, 13 Aug 2007 09:34:14 +0000

Did you install prolific driver too?
Is configurator software works?

3 key driver is realy SideShow driver ?

Jim — Mon, 13 Aug 2007 02:29:27 +0000

Hi all,
My os is vista ultimate.
I download the source code of the 3 key driver,when i debuging the code ,i can not get the value of the "PortName",as follows,

szPorts=_T("SYSTEM\\CurrentControlSet\\Enum\\USB\\Vid_067b&Pid_2303");
szDevParameters=_T("\\Device Parameters");
I change the vid and pid to my device's vid and pid.

LONG gle = ::RegQueryValueEx( hDevParams, _T("PortName"), NULL, NULL, szValueData, &dwValueDataSize );
I can find the "PortName" form the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_1816&PID\7898\01\Device Parameters.

About codes in the OptimusMini.cpp\BOOL COptimusMini::Open()

I do not know how the SideShow dirver to work ,who can help me ?
Thanks.

One of the (very nice) Art Lebedev developers pointer me toward their web page for developers (here: ) which has the Mac and Windows mini 3 SDKs and example code.

Thanks!

Where did you get this Xcode template? I'd love to start playing around creating Mac mini 3 plugins, but cannot locate an SDK or examples...
