First cut, Code Tone library using DAC.
Then, need a good interface for a DAC waveform library.
1) Playback recorded sample. mp3, flac, whatever.
2) "Notes" consisting of multiple sine waves together with note start and
stop characteristics. Permit multiple notes to be played at the same time.
3) Support up to four channels
4) Something totally different?

0018 is ancient and much has changed. Should really upgrade. Especially if we
want to merge back into arduino code base.

Constant folder in avr-gcc seems to evaluate 2^0 to 2. Double check whether
this is really happening, and if so raise a bug with gcc or avr-gcc
folks.

What steps will reproduce the problem?
1. get a sparkfun xmega100 breakout
2. download anything here.
3. become completely stuck.
What is the expected output? What do you see instead?
At least the basic walkthrough. Which pins on the sparkfun do I need to
use to program? Can I use the AVR Dragon? A
What version of the product are you using? On what operating system?
0.18, linux where it says:
falling back to Metal Look and Feel
java.lang.UnsatisfiedLinkError: librxtxSerial: librxtxSerial.so: cannot
open shared object file: No such file or directory thrown while loading
gnu.io.RXTXCommDriver
Exception in thread "main" java.lang.UnsatisfiedLinkError: librxtxSerial:
librxtxSerial.so: cannot open shared object file: No such file or directory
No prerequisites, installation guide, etc.
Please provide any additional information below.
All I want to do is get the bootloader into the breakout board and maybe do
a simple hello world sketch. But nothing anywhere here has details on
getting started between the unboxing and downloading and actually getting
"hello world" on the serial port.
I think I could get an Xplain board working since you give some details
there, but not the sparkfun board.
If it isn't really supported - if there is no way to get it working, it
should say so. If it can be made to work, a paragraph telling me how - I
can figure most things out but you don't even say if I need a Dragon or how
to hook it up I can't begin to guess about the first step.
And java isn't even working properly - The original (non-xmega) 0.18
./arduino works fine and doesn't ask for that library. Maybe it would be
clear if I got it working, but I can't right now, but I'm trying to build
it from source.

TCF0 is used to count micros and TCF1 to count millis. Overflows from
micros
are supposed to generate events that drive TCF1. That isn't working. For
now,
I've hacked things to work by using an overflow interrupt for TCF0 which
increments a millis counter. Really want to fix it to use events.

Just want to let you know, I modified the libraries to get the compiler to
generate atxmega256a3 code. I had to replace TCF1 and TCF0 with TCE1 and
TCE0 in wiring.c since the a3 part does not have TCF1. I modified the
serial library to support all 7 USARTs. Don't know if you are interested in
these mods.

Serial communication was flaky. Karl added hard coded settings to fix it for
38.4K, 57.6K and 115.2K. Would be nice to replace with a formula.

I made the code ugly getting basic bootloading working.
Clean it up.
Check that it works with 328p, 644p, etc.

Code is commented that addresses are word addresses. I seem to recall that
being true for other chips. Is avrdude doing it different for xmega.
If true, this constrains programs to being <64K in size.
Check, if behavior is different, file a bug with avrdude. Should also fix
bootloader to have a third address byte.

bootloader is currently constrained to having at most 64k words/bytes of
program. Add a third byte to address_union, so that it can use full size of
memories supported by mega/xmega chips.
