general mess-up

by grandemahatma on Wed Apr 30, 2008 3:40 am

hallo!
Since a couple of days I have difficulties in loading my programs into the boarduino (sync issues)..
That's pretty strange, because it always worked before. And also because if I insist, after 5-6 tries, the program finally loads.

Furthermore, when I display stuff on the serial monitor (I'm using the arduino environment, of course, with 9600baud) all the letters are mess up.
i.e., when I call Serial.print("Ready") I read this: ¤???åÿ
This, as well, happens 90% of the times: sometimes I can actually read the correct "Ready"..


Does anyone have a suggestion?
thanks a lot
Ale

could be the chip is messed up
another thing is to double check the serial monitor that you have the right baud rate

of course the baud rate is correct.. Could there be another solution to the problem? or is it so very likely that the chip is half dead?

Did you build the boarduino yourself? Perhaps there are some solder connections that are intermittent.

yeah, but it has been working for 6 months.
..and I kept it safe and sound in warm and confortable places.

Have you changed the bootloader or any of the configuration fuses?

It sounds odd that the problem would be intermittent if the chip were
damaged, but it is possible I suppose.

A new chip is reasonably cheap. It might be useful to keep a few spares
on hand anyway.

intermittant problems are often mechanical...oxidation, something going loose, a cold solder joint...
