I am using Windows XP and have the latest FTDI drivers installed. When I plug the unit into my PC, the Pin 13 LED flashes a few times then goes out. It will flash once when I hit the reset button. Wtih my multimeter, I am getting a steady 5v from the "+" and "GND" pins on the chip, while plugged in.
I also tried to upload the "Blink" sketchbook onto my unit, using the Arduino 0017 IDE and I get this error codes:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
Which, from what I read means I'm not getting any communication between the chip and the IDE program.
So my question is, what do you think could be the issue? Did I do a crappy job soldering the board that sits on top of the chip? If so, what do you think could be the issue? Or maybe it's a software issue?
If you need anymore information to help me, please ask.
I have the correct board and com port picked as well.
I'm debating if I have a cold solder point somewhere. I need to pick up a new de-soldering wick tomorrow. I'm just trying to see if someone has experienced this before or if I'm just missing something stupidly obvious.
One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.
if you have there 50512 (FTDI Basic Breakout - 5V) then that is fine, and this is not your issue.
Mine looks exactly like this one, from the .pdf manual for the ardweeny:
I had also contacted solarbotics before I made the purchase to make sure I was getting the right breakout board. I purchased the 5v one. And my multimeter picks up a steady 5v's from the "+" and "GND" on the chip when its plugged in.
So I resoldered the ATmega328 chip and this is what happens when I plug the sucker in.
I plug it in, and the TX and RX lights on the breakout board flash a few times. The pin 13 LED will blink about 10-15 times then stop. The pin 13 LED will also blink once if I hit the reset button.
When I try to upload the "Blink" sketch, I still get this code:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
maybe you can measure the voltages directly from the pins of the ATmega,
VCC,GND,AVCC,AGND. This will help to see if the soldering is fine or not.
I notice from their photos, 3.3V FTDI breakout cable seems to be different from the 5V cable. The TXI and RXO pins are reversed. So pls check the breakout pins are really connecting to TXD and RXD of Atmega, and not the other way round.
You may check against the schematic of Arduino Duemilanove for reference
You could just use jumpers from the TX and RX on the FTDI breakout directly to digital 0 (rx) and digital 1 (tx). (and ground of course) You'll have to manually reset, but that just rules the auto-reset issue. This should rule out any hardware mixups as well.
Also, like stated below: do make sure you try the opposite of what you tried with the RX and TX.. I know that some boards label them funny.. just make sure you try at least once to switch the two.
Also maybe you could post pictures of everything, top and bottom. May be able to answer a few more questions with a visual.
When I soldered my first Arduino onto a protoboard, it took me like an hour to figure out why it wasn't working.. I checked every solder joint, resoldered some.. pulled the chip off, checked it and it worked..
Turns out I had the button wired wrong.. it was grounded.. which is why I couldn't upload. I just mixed up the button connections.
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
A baud rate discrepancy could kick that error, is the ardweeny running the same rate that is set in config, IE If the config is set at 19200 and the board is running at 57600 ( or vice versa ) it wouldnt communicate right.
I am using the Solarbotics Ardweeny and am having similar problems to the ones described here.
Specifics:
Solarbotics Ardweeny
Windows Vista OS
Sparkfun FTDI Basic Breakout, 5 V version
Error Message in console:
Binary sketch size: 1010 bytes (of a 30720 byte maximum)

Background info:
I assembled four Ardweenies and tested them all. The fourth one does not work whereas the other three worked as expected with the Blink.pde sketch available with the Arduino 0021 download.
The LED on Pin 13 blinks about once every three seconds. When I press the reset button, the LED blinks once upon release and then once every three seconds.
When I upload the sketch to the board, the LED on Pin 13 blinks three times and the TX LED on the Sparkfun FTDI Basic Breakout board blinks three times but the RX LED stays off. While this is going on, the IDE continues to say uploading to the board and then I get the error message given above.
I tested the continuity between the ISP headers as connected to the Sparkfun board, GND to both GND pins, 5 V to + and A+, TX Sparkfun pin to Adrweeny D0, and RX Sparkfun pin to Ardweeny D1. I do not know what the CTS and OTR Sparkfun pins do. The Sparkfun header ISP pins GND, 5 V, TX, and RX have continuity to their respective pins. These are also the pins as on the working Ardweenies.
When I tested the board for voltages with the Sparkfun board in place
to GND was 5 V,
A+ to GND was 5 V,
but AR to GND was 0.6 V.
On the working boards, AR to GND was 0 V or very close to it.
