Hi,

I think a lot of people would already have seen this. It looks like it is now available.

Could make an interesting input/status device.

I have bought one for use in my car. My PC is controlled by an encoder and soft switches, and use girder for all display, control and logic puposes.

What I would like to do is send "soft switch titles" and alerts such as speed camera, traffic etc. you could then press the traffic alert and get the full story on the main LCD screen.

Anyway, would be interested in anyone elses ideas and girder solutions for the device.

I just received my black version 2.0....

It took at bit of fiddling with drivers, to get it going under vista (no problems with xp)
but it's working ok now...

I'll build a simple Girder plugin for it over the weekend (they supply C++ code, so it's not so hard (famous last words))....
you won't be able to use the supplied optimus configurator software at the same time!!)

I've connected it via a usb extender and 20m cat 5 cable and plan to 'nail' it to my wall to control lights+central heating

first comments :

* I don't hear any 15Khz noise (a problem older versions were supposed to have)

* I have some concerns about the lifespan of oled displays in general..
(I heard it's especially the blue leds in oled displays that are the problem?), I want to dim the display after some timeout
(but not turn it off, the supplied software simply switches off the displays if you don't move the mouse for x minutes, I don't like that...)

* I don't like the fact that an all-black device comes with a molded transparent copper braided usb cable.. I'll rip it out and replace it with a black one...

They use an 18-series pic processor as a controller

plugin is finished...

see picture

this was created using the gd library with the following code :



local im = gd.createTrueColor(96, 96)
local black = im:colorAllocate(0, 0, 0)
local blue = im:colorAllocate(0, 0, 255)
local white = im:colorAllocate(255, 255,255)
im:filledRectangle(0, 0, 96, 96, white)
im:stringFT(black, "d:\\windows\\fonts\\arial.ttf", 30, math.rad(45), 20,90, "Hello")
print (optimusmini.ShowPicture(1,im:gdStr()))

local im = gd.createFromJpeg("c:\\test2.jpg")
im:stringFT(blue, "d:\\windows\\fonts\\comic.ttf", 30, 0, 0,50, "From")
print (optimusmini.ShowPicture(2,im:gdStr()))

local im = gd.createFromJpeg("c:\\test.jpg")
im:stringFT(black, "d:\\windows\\fonts\\verdana.ttf", 20, 0, 0,50, "Girder")
print (optimusmini.ShowPicture(3,im:gdStr()))


It takes about 1/3 of a second to send a 96x96 pixel, 24 bit colour image to a button.

pressing a button results in a girder event...

I'll publish the plugin once Ron gives me an official plugin id...

note that the gd library needs to be fixed, to allow truecolour png files to be loaded from disk...

wow i hope you're able to release this soon. i've been using am OM3 for a custom kitchen pc i've put together and have been severely disappointed with the supplied software. i've already got Girder running the brains of the computer so this would be great.

<baited breath on>!

just an id for events or also for a config page?

just for the plugin, there's no config page..

(also, please don't forget about my rfxcom receiver plugin that I sent you. You haven't made the plugin and config id that I used for that, official yet. please add those to the list as well, or if they are already taken, please give me some official id's)

Mike,

this is a c++ plugin, not a lua based one...

shouldn't it have a lower number than 10042 ?


thanks for confirming config id 125 and PluginID = 10041 for the rfxcom receiver stuff...

Is it possible to run more than one of these devices from a single pc/girder instance?

theoretically it's possible, (each optimus is exposed as a virtual com port)

but, the girder plugin doesn't support this yet,
and I don't have time to add this functionality at the moment ...

(the source code is included, if anyone wants to implement this)


the official plugin thread is here, by the way :
