Yes, but the driver is supposed to be installed along with AVR Studio so
it shouldn't need to hunt very far for it.
Part of the driver's function is to set information so that Windows and
AVR Studio can recognize what the board is. AVR Studio then installs
firmware into the Dragon itself.

I had similar problems when I was beginning with Avrdude.
Avrdude doesn't use /dev/lp0. Instead

And now?
Can I burn my prog on the AVR?
because it seams like it don't see my AVR:
JanniMainPc:/home/jan-erik/avrdude-5.1 # avrdude -c sp12 -p m8
-P /dev/parport
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
hfuse: c9
lfuse: ef
lock: 3f
Thanks.

It is possible for the strip tracks to have cracks in them, either from

a line of solder over the unused tracks between the micro and the crystal...

There is some magic to making crystals oscillate. Not all crystals

I hope this helps. I don't think most people will have to worry much about
crystals. I doubt that Vincent's problem was crystal selection or the wrong
load capacitors.
That's annoying... because if my fuse bits are correct,

Hi Vince,
I don't know of any problems with the modules you are talking about (that's
not to say there aren't any).
This was one manufacturers 2x20 COG text module, though a competitors
product with presumably a different LCD module did exhibit the similar
faults. The fault was

Sorry for the late reply, but my AVR started again refusing to connect
to avrdude. Spent lots of time on it. In the end it seems the AVR might
be dead for good this time, well at least some or all of the SPI port
pin drivers which I might have killed when powering off the AVR
Hi gents,
I would like your opinions/experiences about using rotary encoders. I
have planned on using one for my project, so ordered one to experiment
with (never used them before).
It's a mechanical one, with the usual 2-bit gray code output.
I was expecting loads of bounces, but got only a

I changed the delay down to 50, 20 times less, but it still takes 885s

David, I will look into this .depend thing but it seems a bit obcure to
me at the moment and since it works just fine with it commented out, I
will allow myself a few days before plunging into the Makefile
