I just recently purchased a Arduino Decimal from Spark Fun Electronics. I'm having the problem that I can't seem to upload anything to the board -- as of today. To begin with I'm using windows XP and I'm running as a limited user (don't know if that matters, tried running as admin didn't make much diff). When I first got the board I followed all of the instructions for installation and didn't have much of a problem. The board TX and RX light flash --like they should -- and the the "L" led blinks continuously (not sure if it's supposed to?).
I uploaded a sketch yesterday and I didn't seem to have a problem, but now when I try to do that the program freezes up and I can't do anything and in the mean time the board's 'L' led just keeps flashing very rapidly. I believe the sketch that I uploaded was the blink one... but I'm not sure if it even worked because I went to bed before I even saw if it was working -- big project for school, don't ask.
I'm not certain if I'm doing something incorrectly or if there is something wrong with my board. I've read most of the recent comments here and tried everything including making sure that the COM port is correct and such. I don't know how to proceed and I'm a little confused on what to do. :o
In responce to the questions:
When I first plug the board in the TX and RX flash a couple of times and then the 'L' LED blinks continuously.
In windows hardware manager, as per se the troubleshooting guide the serial port shows up as COM4 so I'm sure that I'm selecting the correct port. The software only allows me to select COM3 and COM4. If COM3 is selected it gives me an error, so I'm sure that I've been using the correct port.
I don't know if the baude rate it set correctly or if it matters I believe that the touble shooting guide dictates that 15200 is the correct speed -- the default if 9600. (I'm connecting over usb)
I'm still not sure if the problem is my computer, the board, or the USER!
