Re: [PD] pduino test patch: old analog/digital controls
Thanks Hans for making this thing clear - I'll try to find an adequate solution for the rewritten pduino-help asap! best ø On 11/03/2011 03:39 PM, Hans-Christoph Steiner wrote: That confusion originates from the Arduino numbering scheme itself, since it uses A0 for analog pins in analog mode, but then it uses a number when using the same pin for digital things. I think one way to represent this might be to allow the use of A0-A7 pin names in addition to the numbers, but then the confusing thing would be that the analog messages would then be [analog 14 0.2352(. So that's why I thought to try to use only the numbers, no A0-A7, and try to make that as understandable as possible. .hc On Nov 3, 2011, at 6:57 AM, olsen wrote: yo bonitos due to the pduino rewrite I've to reanimate this threat ;) I would like to remove the ambiguity and confusion about this old and new way of enabling the analog pins. old way of enabling the analog 0 pin is sending the following to the arduino object: [analogIns 0 1( enabling the same pin(analog 0) the new school way: [pinMode 14 analog( is this correct? if so what's a bit byte confusing for people is that in the new way pin 14 equals the analog 0 pin - guess this is a peculiarity of firmata? isn't there a possability to use f.e.

I'd believe it if GEM is fastest anyway, but the numbers shouldn't be made to be more dramatic than they deserve, so, that's why I'm asking. How many geos doesn't seem to matter much. A 'Gem gui object' could for example be a draggable geo with a texture, or a set of 5 geo's moving together when dragged. The cpu load caused by dragging is the same in both cases. The percentages in my small test were rough indications as seen in top, for Pd and Pd-extended processes. In OSX's Activity Monitor, the process WindowServer (not shown in top), does a few % as well for any mouse activity, that's what I saw only later. I've done a rather intensive attempt to do all gui's in Gem some time ago. It was promising, but there were a couple disadvantages as well. It's documented on the Pd forum: http://puredata.hurleur.com/sujet-5515-gem-alternative-guis A demo patch 'WaveRefinery.pd' is there (login, post #5), with animated pictogram buttons, toggles and xy-controls in a Gem window.

A 'Gem gui object' could for example be a draggable geo with a texture, or a set of 5 geo's moving together when dragged. The cpu load caused by dragging is the same in both cases. It's like that whenever the textures are already uploaded (and are not being reuploaded) and that there's a GPU that does nearly all of the work. In that case, all the CPU has to do is run the Pd/GEM objects, and when pix objects are idle, all that GEM does it tell the GPU what to do, so it's really fast, even when it's repetitive. But with certain «light» kinds of GPU, the work is split between the CPU and GPU (I don't know whether there are still new devices like that, but my 2005 laptop was like that and I only got a new one this year). A demo patch 'WaveRefinery.pd' is there (login, post #5), with animated pictogram buttons, toggles and xy-controls in a Gem window. It gives a nice impression of possibilities. When you try dragging a circle or square from its edge, it does not work (the click detection does not work, seems to be using a different radius). If you click inside, then the shape jumps so as to become centered, which is not what I'd expect. But it does seem like a quite good patch. __ | Mathieu BOUCHARD - téléphone : +1.514.383.3801 - Montréal, QC___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
