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 or 7 LEDs blinking at different speeds, there is cross-talk between the channels causing the LEDs to blink at wrong intervals (but not in unison), including the onboard one on the Arduino board on Pin 13 which I'm not even sending messages to!
I don't believe it is an electrical problem, as the wiring is quite simple and I decoupled the outputs to the LEDs after the problem first occurred. In fact, the problem persists even when I remove any and all of my own electronics from the circuit!
The blink interval is something in the area of 200-500 miliseconds, certainly slow enough for the comport. Could it be trouble with some of the objects in the [arduino] abstraction?
Any and all suggestions appreciated, as this project needs to go out the door tomorrow morning! best, Derek

Hi, Derek,
One thought that occurred to me: it takes around 16-20 ms to send a message to the arduino and recieve a message back (which has to do with the FTDI chip). This is a round-trip time--I'm not sure what the delay time is like for data traffic going in one way. Perhaps those delays are adding up, when you've got 10 separate LEDs to control?
Have you considered making a test program on the arduino to blink the LEDs at different rates and see if the problem persists? That would isolate the communications from the actions performed.

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 when it has not been sent any messages. After that, a single LED on Pin 2 will start to blink sporadically, especially with more randomized [metro] intervals. If the [metro] controlling the LED on Pin 2 is switched off, it will continue to blink if other [metro]s are running.
Clearly this is a case of message collisions, even though the [comport] object does not report any TX-OVERRUNS.
I'm not too skilled with writing code for the Arduino, so I have no way of running something standalone right now to see if it can be isolated from the board.
I'd really like to have a solution or workaround to this problem, as it's quite an unexpected bug!!!!
thanks + best! Derek

I actually think you will want to code the metro on the arduino. Then, pass only messages to the arduino that will tell it how many ms are between blinks. You could also write routines for synchronizing a pair or more of LEDs, triggered my messages.
To code the metros, the arduino has a routine called millis() which returns the time since the arduino started up. So, I can envision a routine that looks a little like this: L1= time in ms between blinks of LED1 ; T1=time until next blink . . . L10= time in ms between blinks of LED10 ; T10=time until next blink
void loop() { now=millis(); if (now >= T1) { blink LED1; T1=T1+L1; } . . . if (now >= T10) { blink LED10; T10=T10+L10; } }
That's just a fuzzy idea of how I think you can code it. There's probably a bit more timing involved on the side of how long you want the LED's to blink, and of course the message passing/parsing it takes to be able to control everything.

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.

Problem remains the same after upgrade. Looks like I or probably a friend have to write some custom firmware for this project before tomorrow.

After that, a single LED on Pin 2 will start to blink sporadically, especially with more randomized [metro] intervals. If the [metro] controlling the LED on Pin 2 is switched off, it will continue to blink if other [metro]s are running.
Clearly this is a case of message collisions, even though the [comport] object does not report any TX-OVERRUNS.
I'm not too skilled with writing code for the Arduino, so I have no way of running something standalone right now to see if it can be isolated from the board.
I'd really like to have a solution or workaround to this problem, as it's quite an unexpected bug!!!!
thanks + best! Derek

Hi, Derek, One thought that occurred to me: it takes around 16-20 ms to send a message to the arduino and recieve a message back (which has to do with the FTDI chip). This is a round-trip time--I'm not sure what the delay time is like for data traffic going in one way. Perhaps those delays are adding up, when you've got 10 separate LEDs to control? Have you considered making a test program on the arduino to blink the LEDs at different rates and see if the problem persists? That would isolate the communications from the actions performed. Chuck

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 SimpleDigitalFirmata. They are
in File -> Sketchbook -> examples -> Library-Firmata

I am currently arduinoless, but once I get home tonight, I'll see if
I can find the root of the problem.

There were bugs in that version. They have been fixed in the

Once I get a spare moment, I'll update the Pduino .zip on my page. .hc On Oct 8, 2008, at 11:59 AM, Derek Holzer wrote: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 when it has not been sent any messages. After that, a
single LED on Pin 2 will start to blink sporadically, especially
with more randomized [metro] intervals. If the [metro]
controlling the LED on Pin 2 is switched off, it will continue to
blink if other [metro]s are running.Clearly this is a case of message collisions, even though the
[comport] object does not report any TX-OVERRUNS.I'm not too skilled with writing code for the Arduino, so I have
no way of running something standalone right now to see if it can
be isolated from the board.I'd really like to have a solution or workaround to this problem,
as it's quite an unexpected bug!!!!thanks + best! Derek

miliseconds, certainly slow enough for the comport. Could it be trouble with
some of the objects in the [arduino] abstraction?Hi, Derek, One thought that occurred to me: it takes around 16-20 ms to send a message to the arduino and recieve a message back (which has to do with the FTDI chip). This is a round-trip time--I'm not sure
what the delay time is like for data traffic going in one way. Perhaps
those delays are adding up, when you've got 10 separate LEDs to control? Have you considered making a test program on the arduino to
blink the LEDs at different rates and see if the problem persists? That
would isolate the communications from the actions performed.

Problem remains the same after upgrade. Looks like I or probably a friend have to write some custom firmware for this project before tomorrow.
Hello.
There's a very easy way to do this in custom firmware with raw arduino code, using a shift out chip very cheap and easy too find - 74HC595
there's a tutorial here - http://www.arduino.cc/en/Tutorial/ShiftOut
I used this a lot of times and actually I'm using right now in a project, and works very fine. Uses only 3 arduino digital outs.

I used this a lot of times and actually I'm using right now in a project, and works very fine. Uses only 3 arduino digital outs.
for example, in this beat sequencer... http://organismo.art.br/blog/?p=2618
Just in case anyone's curious, here's how the problem was solved. The task, if you recall, was independent control of 10 blinking LEDs from the digital outs of the Arduino. I ditched the Firmata and used some basic Arduino example code instead. LEDs draw about 8.5 mA each in the end (using Kingbright ultra bright reds with 330R resistor) so it's quite safe to run the whole thing from USB power even.
Arduino code and test patch attached.
best! Derek

Thanks for that patch, it was very helpful in tracking down the bug.
I figured it out and fixed it. Please try it again:

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 when it has not been sent any messages. After that, a
single LED on Pin 2 will start to blink sporadically, especially
with more randomized [metro] intervals. If the [metro] controlling
the LED on Pin 2 is switched off, it will continue to blink if
other [metro]s are running.Clearly this is a case of message collisions, even though the
[comport] object does not report any TX-OVERRUNS.I'm not too skilled with writing code for the Arduino, so I have no
way of running something standalone right now to see if it can be
isolated from the board.I'd really like to have a solution or workaround to this problem,
as it's quite an unexpected bug!!!!thanks + best! Derek

The blink interval is something in the area of 200-500 miliseconds, certainly slow enough for the comport. Could it be trouble with
some of the objects in the [arduino] abstraction?Hi, Derek, One thought that occurred to me: it takes around 16-20 ms to send a message to the arduino and recieve a message back (which has to do with the FTDI chip). This is a round-trip time--I'm not sure what
the delay time is like for data traffic going in one way. Perhaps those delays are adding up, when you've got 10 separate LEDs to control? Have you considered making a test program on the arduino to blink the LEDs at different rates and see if the problem persists? That would isolate the communications from the actions performed.

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
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.

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 or 7 LEDs blinking at different speeds, there is cross-talk between the channels causing the LEDs to blink at wrong intervals (but not in unison), including the onboard one on the Arduino board on Pin 13 which I'm not even sending messages to!
I don't believe it is an electrical problem, as the wiring is quite simple and I decoupled the outputs to the LEDs after the problem first occurred. In fact, the problem persists even when I remove any and all of my own electronics from the circuit!
The blink interval is something in the area of 200-500 miliseconds, certainly slow enough for the comport. Could it be trouble with some of the objects in the [arduino] abstraction?
Any and all suggestions appreciated, as this project needs to go out the door tomorrow morning! best, Derek -- derek holzer ::: http://www.umatic.nl ::: http://blog.myspace.com/macumbista ---Oblique Strategy # 95: "Is something missing?"

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. Seems more like message collisions, as Charles mentioned.
thx, D.
