I recently purchased a lilypad arduino (ATmega 328) and an FTDI cable (this one: http://www.sparkfun.com/products/9718). I just reinstalled the arduino software just in case I hadn't previously installed the necessary FTDI drivers. However, I keep encountering the following message every time I try to upload code:
Problem uploading to board.
avrdude: stk500_getsync(): not in sync: resp=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
I'm running OS X 10.6.7. I think it might be a driver issue. Also, the board doesn't light up when I plug it into my computer. Does anybody know what's going on? Please help! Thanks!
Okay, I just found this post on the Sparkfun forums: Lilypad Arduino - SparkFun Electronics Forum apparently you need to hook up another power supply to the lilypad even when it's connected to the computer? I tried connecting a 5V power supply to the lilypad, and the LED on the board blinked, but then I received this message:
avrdude: stk500_recv(): programmer is not responding

If you are using the FTDI breakout board, you should make sure that none of the solder joints on the board are touching the Lilypad. Sometimes I use a small piece of felt in between the FTDI breakout board and the Lilypad Arduino just to be certain. You also need to make sure that you have no power on the Lilypad at the same time as you have it connected to the computer. If the Lilypad is connected to the computer, it is already getting power from it!
The best thing to do is unplug any additional components from your Lilypad, and connect just the Lilypad to the computer via USB. You should be able to get this working. If not, make sure you are not making any additional contacts with anything conductive. Make sure the solder joints on the back of the FTDI board are not touching any of the pins.
