1  Forum 2005-2010 (read only) / Bugs & Suggestions / yabb notification not working on: November 18, 2008, 11:28:49 am
Ever since arduino moved to the new version of yabb a few months ago I stopped getting notification emails.  I'm subscribed to get notifications for new topics on several boards.  (This isn't a spam filter thing.)  Any ideas about what I'm doing wrong?  Is anyone else having this problem?  thanks!

the newest version of the LilyPad does use an external resonator, but earlier versions didn't.  The lilypad bootloader that ships w/ the software is still the internal oscillator version so that people with older boards won't render them useless if they burn them w/ the external oscillator bootloader.

the internal clocks on the AVRs are surprisingly good (much better than PICs in my experience.)  You can't do high speed serial communication, but you're fine up to 19200 or so... :-)

OK, first of all, did you remove the AVR chip from the Diecimilla before you tried to program the LilyPad?  Two chips attached via the same communication bus will really confuse the computer.  Try that first!

Second, I have to confess that I've never tried programming the LilyPad via the Diecimilla board because I thought that the auto reset functionality on that board might interfere with the LilyPad communication.  This is why I recommend using an NG.  But, your post makes me realize that I should have concrete results to report back on with Diecimilla.  I'll do tests as soon as I get a chance.

Third and sad possibility is that you may have fried your LilyPad when you fried your mini USB adapter.  You probably had a pretty bad power-ground short going for awhile (via the coductive foam) and this makes all electronics unhappy.  If you'd like to send me your LilyPad you're welcome to.  Email me & I can give you my address...

I'm sorry that you'd had a bad experience!  I trust in your competence programming wise & I know how you've feel.  I have been in your boat many times.  From this discussion, I suspect that it was the conductive foam that killed things for you...  Don't give up on the LilyPad yet!

& send a comment to SparkFun about your connection travails, requesting a nicer interface ;-)  This will help me persuade them to invest in a redesign.

New tutorial for connecting the LilyPad is now here:

pic of mini USB adapter versions 2 & 3 showing the labeling issue

Again, in all versions of the mini USB adapter that I have encountered, you want to connect the second from the left tab (labeled RX in version 3, but TX in version 2) to RX on the LilyPad.

OK after some more investigations, I have found that some versions of the Arduino mini USB adapter had different labeling.  The USB connector in the pictures on the Arduino website labels TX as the second connection from the left while current boards label that same connection as RX.  I checked the same picture you did ticklr when I posted my first reply, but was then confused when I returned home and other, more recent, boards I had were labeled differently.  So, I thought I had just messed up in my first post.  I don't think the wiring on the Arduino USB boards changed, I suspect that  just the labeling did.  So, you always want to connect RX on the LilyPad to the connection that is second from the left on the Arduino mini USB adapter (labeled RX in your photos ticklr, but--ack!--TX in the ones I took).

FYI, swapping the TX and RX connection to your LilyPad won't do any harm. Your LilyPad just won't work when they're not hooked up right.  What killed your Arduino USB connector was leaving the conductive foam on the Arduino USB board :-[.  I'm going to spend all day tomorrow working on updated documentation and tutorials and I will put up a post once that's done.

I'm a dork!  just got home from a long trip & had a chance to take a closer look at everything. fornzix, you're right.  tx on the Arduino mini USB->serial adapter should be attached to tx on the LilyPad and ditto with rx.  For many other usb->serial devices things would be the other way around--that is you'd attach rx to tx, etc.  Everybody, please be aware that this connection is sensitively dependent on the usb->serial device you're using!

& I promise there's nothing wrong with the traces on the LilyPad or the USB mini adapter.

I am working on a new version w/ better connection!  Stay tuned & please, send me design feedback: Leah.Buechley@colorado.edu.

Anyone who is having problems, could you post a photo of your mini-->LilyPad connection?  

&, try:
* physically press on the tx/rx connections during the upload process to make sure you're getting good contact.  If bad contact w/ alligator clips is what's causing your problems, make a coaster for your LilyPad ( http://www.cs.colorado.edu/~buechley/LilyPad/coaster.html)
* swap tx & rx (maybe they're just accidentally swapped in your setup)
* make sure your LilyPad is getting power from the USB adapter.  There are different jumper settings on the USB adapter that let you use an external power supply OR the USB port for power.  If your LilyPad is blinking when you press the reset switch, you are getting power & things are OK, otherwise, find the right USB jumper setting.

you use conductive thread & sew it into things!  smiley

hey fornzix.  since the LilyPad is made for wearables, it's not ideal for breadboarding & more traditional electronic tinkering.  If what you're looking for is a general purpose Arduino that can run on 3.7 volts, it's not hard to make your own ;-)  

Check out Ladyada's fantastic tutorials & her breaduino kit.  To make the breaduino run on (almost) the same voltage range as the LilyPad, just leave out the voltage regulator components & connect power directly to VCC on the microcontroller.  You'll want to carefully look at the ATmega168 data sheet & Ladyada's schematics to get this right.  Note that if you do this, you'll only be able to power your breaduino w/ a max of 6 volts--anything more will kill it.

main tutorial page is now here:

new guide for attaching the lilypad can be found here.  this should help with any confusion people have been having about TX/RX issues.

hmm...  OK so, first of all, are you getting blinking on your LilyPad when you hit the reset switch and + & - are connected?  If you're not then either + & - aren't hooked up properly or the LilyPad is dead.  If you previously got a blink but now you're not getting one, then there is likely a short in your setup & you are probably frying the lilypads &/or other things...  Make sure there are no shorts & make sure the lilypad is getting power: measure across + & - on the LilyPad & you should see 5 volts.

If you are getting a blink, try clicking upload in the Arduino IDE *before* you hit the reset switch during the programming process.  This will give you a little more time for communication.

If this doesn't help, it's got to be some problem with your setup.  I know it's a pain, but just go through your setup from scratch & check everything again.  Did you install the drivers properly?  Are you sure you've selected LilyPad in the boards menu?  Are you sure that the NG AVR chip is out of the board?  Are you sure you have the right serial port selected?  Are you sure you haven't accidentally swapped tx & rx in your LilyPad hookup?  Try swapping them just to double check.  Is there possibly a short on your NG board?  Also check out Lady Ada's excellent troubleshooting advice here: http://www.ladyada.net/learn/arduino/help.html

fyi - I know that Arduino 10.0 & lilypad work on mac 10.4 ppc... I'm running it on 10.4.11 & everything's OK...  Good luck!

cheers,
Leah
