hmm thats no good! But i suspected as much. Oh well.

I have 2 of them from mouser also...

I'm still thinking about how to interface it, I must check girder out see if it is possible to emulate the knob movements when there is a change of key being held down....(encoder as I posted previously)

I can try to snap some pictures if you guys want....

Royn, you got that other thread we discussed the control in bookmarked? Could d with a link.

here ya go!

if you have some more info to give me about what you think would be the best way to interface this let me know... I'm thinking about it and would like to build this ASAP!

I'm also going to have to start looking for a good knob for this.... I wanted something i-drive like, or maybe like the volume knob on the BMW radios... discreete and easy to grip...

yeah, as i said over on the other thread. The AIMEE guys are looking into it but we have a lot on. And we dont have any hardware. I need to get looking for a knob too and design the LED lighting (don't ask - its gonna be a PITA!)

We are aiming for USB.

I was hoping someone would start on something like this (i'm still in design stage). Do you guys know of any front ends that will easily allow this kind of control/input, or will it have to be girder/make your own app.
I'm thinking that I don't want a touchscreen and learn how to do some skinning for one of the front ends, and make the whole thing work similar to the BMW system.

Frodo & AIMEE (as i am building one with the AIMEE guys!), dunno about the others

RR will support it too... probably very quickly if you send guino a sample he can add it in a matter of days!!!

but with girder it might be even a simpler solution!

I've only ever done really basic 2nd year uni level c programming, not got a grasp of this kind of stuff to do it within a reasonable amount of time, or quality.

I have a adapter which allows me to connect a playstation 1/2 pad to my pc, its detected as a USB HID device. I was thinking how difficult it would be to copy some sort of game controller support from an open source game and use that within a frontend. Not sure how difficult it would be though, probably more hassle then some with enough skills to do it from scratch.

Girder has a HID plugin which might prove useful. If you check ot the other thread about this then you will see some guy got the encoder to work with a hacked mouse scroll wheel - nice!

Damn this is confusing! We have 2 threads about the same device!!!! ARGH!

affie · 04-28-2005, 01:42 PM

I assumed girder could interact with HID devices, its just that I was hoping it would be natively supported in a front-end, rather than having a seperate piece of software.
I'm going to try to figure out the HID, but my programming skills in general are limited or specifically DirectInput (Windows - DirectX) / Linux HID are none existant. And maybe i'll get lucky and find some GPL'd HID code

.

At any rate, it seems like the HID devices have some sort of built in firmware that tell the OS what kind of functions it has. This means that if anyone created an encoder for the type of things we need it for, we will have to understand how to program firmware for our device/cotroller as well as support on the host (e.g. FrodoPlayer, AIMEE, etc).
