31  Using Arduino / Project Guidance / Re: Pin 13 led circuit conflicts? on: August 12, 2011, 05:58:57 pm
Well as I told lefty, another discussion in a different section about possible shield ideas lead me to consider adding LED status circuits to each of the digital lines on my Cidekick project http://arduino.cc/forum/index.php/topic,67044.msg493322.html#msg493322 but I was trying to figure out how an isolation circuit would work for each pin or if it was even needed.

The idea was an LED shield that would show the status of each pin high or low and I was thinking RGB for the pwm pins rather than just fade.

The whole idea would only work if it it could be electronically transparent, meaning not affecting other circuits or uses to display the status and if it was low component count.

I would also only use it on outs and make it disconnect on pins being used as input.

Any thoughts, circuits, caveats?

I know I have seen problems talked about before but looking for pin 13 in search here is like looking up the word the on the internet.

?


Thanks Again Lefty, I should probably just put you and few others like westfw, grumpy mike, on some kind of retainer so I can repay you for all the help you guys supply.

The search term "pin 13" in the arduino forum search returns so much signal to noise because pin 13 is more commonly talked about in posts than any other pin on the arduino, that it is practically useless to try to search for that term, GRIN.

Can anyone give me examples or explain how the LED on pin 13 can conflict or mess up a project using that pin?

What about a status led on a PWM pin what would or could be the loss or conflict?

I know I have seen problems talked about before but looking for pin 13 in search here is like looking up the word the on the internet.

Thanks again lefty, just wanted to confirm.

Thanks lefty,This in replacement of the pullup resistor in the same configuration?
36  Development / Suggestions for the Arduino Project / Re: Regression between uno and uno R2 VALIDATED. HARDWARE PROBLEM CONFIRMED on: August 09, 2011, 02:08:49 pm
I had some communication with the arduino team, which by the way confirmed a R3 uno that will include a diod fix.

I, too, would like an open discussion on that matter. At least a public sign of activity on this topic would be a nice move. Silently correcting a problem is not really what an open source project should do imho.

Could someone describe the diode fix, can someone participating sum up?
37  Using Arduino / Project Guidance / Re: Most common Insertables, Boarduino, Ardweeny, RBBB...? on: August 09, 2011, 01:45:49 pm
Anyone have any common insertables that have been missed or not in the list?
38  Using Arduino / Project Guidance / Re: Most common Insertables, Boarduino, Ardweeny, RBBB...? on: August 08, 2011, 04:08:34 pm
I do have a few tqfp-adapters with chip, capacitors and crystal on top. Two are insertable, but whether it is most common ?

Yeah most common, was trying to figure out how many besides the boarduino, were being used by most people.

Looks like I have the pretty common list already.

Teensy from PJRC:

Thanks for the info, but Im mainly talking about ones that have arduino compatible pin outs, 14 digital 6 analog

The fio is pretty cool, I hadn't had much exposure to it.

Anyone have a picture of the fio inserted in a breadboard, all the pictures I could find were only the board it self.

What are the most common Arduino breadboard insertables, arduino compatibles that can be inserted into breadboards?

The ones I could think of were Boarduino from adafruit, both variants dc and usb, ardweeny from solarobotics, rbbb from modern devices.

Are there any other common ones in that sort of format?
41  Using Arduino / Project Guidance / Re: Is this possible? on: August 03, 2011, 01:05:17 am
Yep back to the no go pile the thought game goes, it needs to be maybe even 64 out of 64 not 1 out of 64 and in the application I would probably use it in it would be more like 200 connections. Oh well thanks for the info.
42  Development / Suggestions for the Arduino Project / Re: SFTP Programming for Ethernet Arduino on: August 03, 2011, 12:37:34 am
I was wondering if the TFTP (Trivial File Transfer Protocol) could be built into the Ethernet Arduino's bootloader so that during the loading if a pin was held high or low it would enter TFTP Programming mode which would in essence allow you to program the Arduino via Ethernet, i.e. via the TFTP protocol, something which many Routers and similar network based devices offer.

I am unsure on if it would A. be possible or B. be something people would be interested in, but primarily, C. I have no idea how it would be implemented.

I was looking forward to this because I could swear that was the idea behind the new Arduino ether they were developing, but it has recently limped into the wild with very little fanfare and it seems like it is actually just  an arduino coupled with the arduino shield but combining it to one board, instead of two.

I believe john oxer of freetronics had the jump on them on that in his EtherTen and it even has POE and an sd card.

I know he does great hardware,  Im not sure how he is on the software side but I bet he is the one we should be checking in on for this as he definitely has ether and the arduino down.
43  Using Arduino / Project Guidance / Re: Is this possible? on: August 03, 2011, 12:24:16 am
It definitely raises my interest interest in the possibilities, I was thinking that many connections would need to work with many independent connections at once, am I correct that what you are saying is with 9 chips I could choose any 1 of 64 connection, but only 1 at any time?
44  Using Arduino / Project Guidance / Re: Is this possible? on: August 02, 2011, 08:19:56 pm
Thanks for the ideas, it was mostly a proof of concept search, rather than a full project, it looks like it wont be feasible or or at the very least not cheap enough to produce.

Thanks again

Yes relays was the way I had gone and hit the wall, I thought I would throw it out there, because as I said I get basic electronics but thought there might be something I missed.

The reason I asked was I had a previous led project that used a ton of pins and then I found the magic of charlieplexing, just wanted to overturn a few rocks to make sure I wasnt
missing something similar for this problem.
