Lilypad Arduino

Welp, I got my wicked-cool Lilypads, but.. I'm having problems getting anything to load.

Because I bought a Modern Device barebones arduino, I'm trying to use one of these:

pinout:

2497×1813 215 KB

I have the lilypad powered by the lilypad power supply, and I'm only using the TX and RX pins on the programming cable.

Here's the result of trying to load up the Blink code with arduino "10.0", aka 0010 alpha.

Binary sketch size: 1110 bytes (of a 14336 byte maximum)

avrdude: stk500_getsync(): not in sync: resp=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I even loaded up the new FTDI driver that ships with the 0010 alpha. Mac OS X, 10.4.10.

... but.. still I get the error.

you need to use
+5V
ground
rx and tx
try swapping rx/tx also, in case its a labeling issue.
dont swap +5v and ground tho :wink:

Oh. Ok. I know the lilypad power supply is using a 1.5v cell, but I figured it was stepping up to something more, yeah? I'm not really very experienced with electronics, I just keep pretending I understand these things until I hit a brick wall... which is frequently. :slight_smile:

The only thing that tripped me up with that is that I tried using the current from the USB cable, which should be 5v, and it didn't seem to even power up the board. I thought maybe I got it wrong, but I checked my connections and it looked ok... Hmm.. I'll have to cannibalize one of my other projects and grab the 5v power supply and see if it works better.

Thanks very much for your input, Limor!

Ok, that didn't work. I just used this 5v power supply:

Still getting this error:

Binary sketch size: 1110 bytes (of a 14336 byte maximum)

avrdude: stk500_getsync(): not in sync: resp=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

and I tried swapping tx/rx, same result happens.

hi

an identical error is described by several users in this thread:

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1187909552

Doe the LED blink on startup to indicate the bootloader is there and working? Is there even an LED on the Lilypad?

D

There is an LED on the board. It does a triple flash on powerup, waits ~10 seconds, and repeats the triple flash. (and repeats the 10 second wait, triple flash, etc...)

7

Did you try the suggestions in the troubleshooting guide (http://www.arduino.cc/en/Guide/Troubleshooting#upload)? Do you have any other Arduino boards? Can you upload to them?

Also, try the final Arduino 0010 release: http://www.arduino.cc/en/Main/Software

Yes, yes, and yes.

Ok, thank you! I will try that.

upgrading to 10.0 final did not help. :cry: I get the same error message.

10

Did you tie the grounds together (of the FTDI cable and LilyPad)?

triple blink... isn't it the old bootloader that does not support autoreset? I don't know lilypad, does it use the new or the old bootloader?

LEDs triple blink, but do not seem to want to receive programming.

The board does not appear to be powering up at all in this case.

13

Have you tried the 2nd configuration but switching TX/RX?

14

One basic question:

Are you pressing the reset switch to upload the sketch?

15

Have you tried the 2nd configuration but switching TX/RX?

Yes. Just now, here's the resulting failure message:

avrdude: stk500_recv(): programmer is not responding

Yes, I am.

17

Wait... I got it.

Thanks everyone. :slight_smile: It works. Never trust a hidden connection. I cracked open the connectors I have soldered to some header pins and found them transposed to what I thought they were. User error strikes again! USB to TTL Serial cable works great for TX/RX and power+ground.

Sorry everyone! I'll go back to lurking!

18

did anyone else notice that there is no resistor hooked to pin 2? it doesn't appear to be wired up out of the box for TTL.
http://www.sparkfun.com/datasheets/DevTools/LilyPad/LilyPad-MainBoard.pdf (this schematic could use some labeling..)

while pretty, this thing is super bare bones. (more base bones than Paul Badger's BBB)

try putting a 10k resistor inline on the 0/RX

lol, I just noticed page 2 where you said you got it. =)
