opengauge development: gunio technical considerations

I had to load the USB drivers, then used comm port 13...

jimboradley, it would also be helpful to know which operating system you are using. I can assist with Linux related issues since that is what I use.

[jimboradley]

Wow, thanks for the response. Shoulda done this first time around, but here's what I posted at the arduino site. I think it's got all the info I could scrounge up. Let me know if there's any other pertinent info I can gather. I'd really like to get this going.

Hi everyone. Like many people, it seems, I'm having trouble uploading sketches to my board. Here's what I'm using:
Windows XP SP2
Freeduino Serial v1.0 Diecimila compatible (from nkcelectronics.com)
a USB to serial converter cable set to
19200 baud
8 data bits
no parity
1 stsop bit
no flow control
using Arduino0011 (tried 009 also, but didn't work)

I've never been able to upload a sketch to my board. I tried all the tips in the troubleshooting section. Here is the output from when I try to load my sketch:

avrdude done. Thank you.

I've tried wiring my serial connector up to itself, and it echoes the characters I transmit from the serial monitor perfectly, so I don't think my cable is a problem. I also tried tieing my rx and tx pins together and transmitting stuff using the serial monitor. The stuff that comes back on the serial monitor is usually slightly garbled, sometimes every character comes back wrong. I transmitted the English alphabet several times and maybe one time in 5 it came back with all 26 letters the same. Not sure if this behavior is expected or not.

I do get LED 13 to flash when I reset, but it doesn't look like a triple flash. Seems like it just flashes every one second constantly. When I try to upload something, it looks like the LED flashes an extra time or two when avrdude first does ser_open() and stk500_getsync(), but keeps flashing every one second.

Anyone have any insight into what I'm doing wrong? Thanks in advance.

From reading some FAQs I was under the impression that high port numbers could be a problem and that the baud rate was 9600 in some cases. I have no actual experience with the board so I probably do not know what I am talking about. DO NOT take my word for it.

[jimboradley]

Well, I'm set up on COM1, I think, so the port number shouldn't be a problem. I thought I tried playing around with the baud rate, but I can try that again, when I get home.

[dcb]

what com ports show up when you go to:
tools->serial port

[jimboradley]

I'm at work, now, so I can't check for sure, but I think it's COM1 and COM4

[jimboradley]

Yep, just checked. COM1 and COM4 show up.

if you unplug the usb part of the cable and restart arduino, does the list change?

do you have a standard serial cable handy? I'm not convinced the usb->serial adapter is recognized.

Also, if you can jumper power to the duino or re-orient the power plug, you can plug it straight into the computer serial port (if you don't have a cable):
