Nickerbocker,

IF you have a fix for my library, submit it as a pull request on github so I can add it to the main library code, then everybody will have it!

Haha! man you weren't kidding.

I have a teensy 3 from the initial kick starter campaign. I just won't be able to touch it until after the wedding. The only part that might not make it compile is if the Teensy port changed the HardwareSerial object type at all, which I doubt. It's the only part of the library that really interfaces with anything else in the environment.

And thanks for the gift, you are too generous.

If the beer helps me survive the wedding, it should come out of the wedding fund, right?  smiley-grin

IMO, this is a totally under-appreciated work,

I also agree that EasyTransfer library is a great contribution to the Arduino community and warrants wider exposure.

I don't think I've ever had a forum post make me blush before. Thanks guys. I should really check these forums more often. Keeping up with the support emails/comments on my own site is almost a part time job as it is. I've been getting 15k hits a month just on my 3 main Arduino libraries.

It's funny that Easy Transfer started as just some idea I had on a Sunday and threw it together in a few hours. I was actually initially embarrassed when the main blogs wrote about it. I didn't feel it did anything amazing or really worthwhile. Reading through the Arduino forum now I see it's really getting some use.

FYI, wedding is in 2 months. I'm ready to skip it for the courthouse. Worst part is dealing with the parental units. Wish me luck.

Hi, this is the author of the EasyTransfer library you are using.

It might help if you read the readme:

Quote
*   The protocol is as follows:
*      Header(0x06,0x85),SizeofPayload,Payload,Checksum

And maybe I didn't make it crystal clear on my blog post, but the library doesn't encode the values in any special way. It simply copies the raw binary out of memory and transmits it. So the binary you are seeing has the numbers 'encoded' the same way the AVR (Arduino) stores them in RAM. It looks like majenko figured that out and sent you in the right direction.

I've added a feature request to allow saving the hex file to project directory. Please go vote/comment on it so it gets support.

6  Using Arduino / LEDs and Multiplexing / Re: Update: ShiftPWM is more than twice as fast now and has a new home on: August 14, 2011, 10:20:46 am
This library is great, tested and will be used for my girlfriend's project.

But, has anyone brought out the point that using regular 74HC595 shift register is actually a bad design as you are forcing it to drive harder then it's rated for?

Yes, each IO is rated for 20mA, but supply/GND current is only rated to 70 mA. All outputs 'on' would be 160 mA with 20mA LEDs. 160 > 70

I suggest a TLC5916 instead as it's rated to drive LEDS like this and it has built in Constant Current driver, so you don't need to add resistors in series with each LED.

Ok, thanks.

We gave it a try when the computer booted up and saw the arduino but not the other FTDI device. It did not fix the problem: :/

I only know enough linux to be dangerous, another team member is good at linux but hadn't heard of the command. I googled it quickly and it looks pretty useful in this regard so we are going to give it a try.

Any suggestions for what we should be lookign for?

Oops, I do mean version 11.3
10  Using Arduino / Installation & Troubleshooting / Arduino and another FT232 device randomly don't appear after boot OpenSUSE 10.3 on: August 11, 2011, 09:41:06 am

I posted this hear in case any linux Arduino users had experienced this problem.

I have a embedded computer running OpenSUSE 10.3 (stuck with that version) that has USB device issues.

In reality, it has two USB devices attached, both FTDI FT232 USB to Serial Uart driven hardware, one is an arduino. Both usually are at /dev/ttyUSB0 and 1 when everything goes right. The latest FTDI driver is already in the kernel.

Randomly however, when it boots one or both will be missing in dev.

If we only leave one physically attached before booting, sometimes it comes up ok, the other times there's no listing in /dev/ or lsusb. But when we do run lsusb once and watch the system log, suddenly the device is found and 'attached'. Then it works fine.

I've repeated this with another test USB device (and old cell phone that gets installed as a ceullar modem) and the same thing can happen. It will randomly be missing from lsusb listing till lsusb is run once. IE, run it once, no listing, run it again, then it shows up and the system log saya it was just attached.

If we leave both, sometimes one device (Call this one A) is ready to go, but device B is missing. If we unplug B, A dissapears from /dev/ and the system log says A was unpluged. The when we reattach B, both show up in /dev/ and the system log reports two USB devices were attached. running lsusb doesn't fix one or both missing when they are both physically attached.

This is an embedded system and we need both to be discovered at boot 100% of the time. Any ideas what might be going on?

I'll have you know this isn't just any old random thread...

True, this is a good thread.  smiley-grin

 Now we just need to get the dev team to read it and listen to our requests. I'd really like my hex file without the hunt.

if you ask on the forum, people reply on the forum.

I didn't ask on the forum, I posted a link to my tutorial for people to find. CrossRoads read on my tutorial elsewhere, came back and asked on the forum.

Quote
No you're not

No I'm not what? Are you saying I didn't write a tutorial?

Quote
lots of people have written tutorials

Did I say otherwise?

none of us like that way of talking

What way of talking? Defending myself when someone chases me down in an unrelated post to go "No!, You're wrong!!". Taking aware from useful discussion for personal vendettas.  Apparently you are ok with people doing that? I guess that's an acceptable practice here then.

There's no point in continuing this further. I just won't respond next time and save other random threads from getting junked up.

CrossRoads,

You followed a link to my blog, read my tutorial and came back to the Arduino forum to ask me a question about what you read. It actually took you more time to come back the the Arduino forum to post the question then it did just to stay on the article.

You misread my tutorial and had a question I had to respond to and clarify. Now if anyone else has the same question that came from another source like the post on hackaday or another forum, I have to answer it again. And I'd have to check all the sources I posted to see if people had a question. I'm the one writing tutorials for beginners and you are asking me to spend more time chasing you down? Really?

I posted the link with synopsis here for people to find when the use the forums search function looking for a related question/issue. That should help beginners here find my tutorial when they need to.

And instead of PM'ing me you hunt me down on an unrelated thread to call me out and junk up someone else's topic? Is this really how people behave here?

Admins, please remove this and CrossRoads unrelated post. I don't want to take away from the feature request discussion.

As they're testing beta at the moment and it's still hidden away in some random temp folder I doubt it's going to change :s

This sucks, there's many people asking for this to be added in this thread and elsewhere. Why are we getting ignored?
