Very simple question: what is an object that can low pass filter floats (not ~)? is there a searchable database on pd objects? googling only found this http://en.flossmanuals.net/PureData/ListofObjects cheers, Martin ___ Pd-list@iem.at mailing list

Hello all, hello Roman, I try your method with X+Y=1 and 0X1 and 0Y1 and your description for the patch. So i get this patch. It seems that i get strange result, no ? Or i miss something ? ++ Jack patch.pd Description: Binary data Le 8 oct. 08 à 15:58, Roman Haefeli a écrit :

[PD] digital write problem in Pduino

2008-10-08 Thread Derek Holzer
Hey all, I'm using the new Pduino 0.4beta2 and Firmata0.4beta3 with Pd-Extended 0.39 and 0.40 and an Arduino NG (Atmega16 IC) to control 10 separate LEDs via the Digital Write pins 2-12. Each has the possibility to blink at a different speed. What I've discovered is that if I have more than 6

Maybe with 8 or more LEDs you are pulling too much current and the board is resetting or doing flakey things because its power supply is glitching. Especially if you are powering it from USB. Martin Derek Holzer wrote: I'm using the new Pduino 0.4beta2 and Firmata0.4beta3 with Pd-Extended

Hi Martin, I checked the draw of each LED, and it's about 15 mA. Should be enough when the Arduino can take 300 mA, but like I said the problem persists even when all my electronics are disconnected. And so far I've only tested it with one LED plugged in, trying each channel individually.

Attached is a diagnostic patch which demonstrates the problem. This problem can be demonstrated using only the Arduino board with a single LED (plus current reducing resistor of 1.5K) connected from pin 2 to GND. At 7 simultaneous [metro]s, the on-board LED at Pin 13 starts to blink, even

There were bugs in that version. They have been fixed in the version of Firmata that is included in Arduino 0012. Burn that version to your Arduino and use the regular Pduino pd patches. Once I get a spare moment, I'll update the Pduino .zip on my page. .hc On Oct 8, 2008, at 11:59 AM,

I'll take a look and see what I can find. You could also write an Arduino firmware using Firmata as a library, then just support the things you need to have working. Perhaps the timing of the analogIns or something like that are interfering. Look at the examples in Arduino, like
