HID parsing for Pd
by Hans-Christoph Steiner 24 Jan '06

24 Jan '06

So I had a meeting with Tom Igoe (ITP/NYU professor and co-author of Physical Computing) yesterday to discuss how to make generic Pd support for sensorboxes. We agreed that the best approach would be to propose a standard protocol for sensorboxes to support, regardless if they are USB, serial, parallel, etc. (MIDI would probably have to be distinct). We also agreed that HID makes a lot of sense as the standard protocol. (OSC might be a better choice too. Maybe. But then you loose the possibility of emulating mice, joysticks, etc. and having them "just work") (It was funny, during the meeting, we'd discuss various ideas, and come to a conclusion. More than once, I said, "oh wait, the MultIO already does this...".) So in order to make this work, on the Pd side of things, there would need to be an object that can interpret raw HID data and output in the same format as [hid]. This object would not need to have the same limitations that the USB HID implementations have, it could have different MAX values that the USB Usage Pages or the Linux input.h types. Anyone know of some USB HID parsing code to start with? (On a related OT question, how hard would it be to port MultIO/PIC code to Arduino/ATMEL?) .hc ________________________________________________________________________ ____ As we enjoy great advantages from inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously. - Benjamin Franklin

Hi, question on the [ascseq] object. Is there any reason why it wont parse space (32)? Thanks, Timon.

GEM Pause video
by Jonathan Goodwin 24 Jan '06

24 Jan '06

Is there a way to pause a video file being played back through GEM? (OS X) I'm currently using a Playstation controller to trigger video playback, which I am stopping/starting by routing a signal to a toggle controlling the "auto $1" playback message. (This is all the same as in the GEM help files.) But doing this causes the video to go back to the beginning each time, rather than pause it. Thanks, Jonathan

PiDiP on Athon64?
by John Harrison 24 Jan '06

24 Jan '06

I noticed that the effectv site mentions support only for Intel IA-32 architecture. Does this apply to PiDiP, then, as well? So...if I use PiDiP, for example, on an Athon machine, am I going to get inferior or unwanted performance? -John

Sound still not working.
by RG 24 Jan '06

24 Jan '06

hello list. The problem with my audio in pd still isn't solved. so I took some screenshots of the settings. -- this one is what's under the "Media" menu item in the main PD window: http://img376.imageshack.us/img376/4224/mediamenu9ip.jpg -- this next one is the actual audio settings for PD: http://img485.imageshack.us/img485/3884/pdaudiosettings0yj.jpg -- the final picture shows my system sound settings: http://img25.imageshack.us/img25/6899/systemaudiosettings0bo.jpg Also, just a note: The systems sounds work fine. it was actually kinda weird. I was workin on some PD stuff, and I tested a sound, then worked for a long while, then went to test the sound again, and it didn't work. I did everything i could think of but nothing was working, so I posted to the list, and so far, none of those solutions have worked So that's my current situation. no sound, and no idea of how to get sound. Thanks for all your help, RG

RE: [PD] program control

Hello, in response: >What not build the DVD playback stuff into a Gem patch? I don't really know how to use gem. I'm not even sure if it's installed correctly. I would love to learn how to use it though. >Why would you want to use your dvd player?? hmmm maybe this wasn't clear enough in the original message. I am in college, and the dorm I live in doesn't have enough room for a TV and DVD player to be permanently setup. so.. I use my computer to play my dvds. I want to use the joystick to control the movie because the desk is across the room, and even though it's only 5 steps, controlling the volume (and other controls) without having to get up would be a great help. >PS: I think you can use mplayer (linux) and drive it with a joystick as >you suggest. I am running off of WinXP (unfortunately). so I assume that program wouldn't work for me. thanks, RG -----Original Message----- From: B.

hi list. i'd suggest to use an external recorder for video. Personally, I dont find the quality of recording with [pdp_rec~] statisfying. How restricted does pidip appears to be? and why? real rebels drink vegetable juice, cider or tea, and absolutely not coloured sugar water. best regards daniel .
