small RAM compression
I found that lzo still requires too much RAM: 64K. I will consider rolling my own GPS specific compression routine, but for the first pass wanted to try a generic compressor....

Battery Status Indicator
Have a look at MAX products, e.g. max603/etc - not only do you get adjustable voltage regulators (3.3/5v/etc) but also low-battery outputs and so on -- the datasheets +...

writing to smartmedia (ssdfc) or something similar
Try using MMC, even easier than CF, and most AVR have an SPI interface you can use.

Again these pointers ...
Is it time for a forum called "Programming Basics", as these questions are orthogonal to AVR?

Project ideas
Please don't make a datalogger or a MP3 player - these are all so average and have already been done. If you want a good project, make it interesting enough so that when you're...

Can this routine go in an ISR?
I have ISR's post events into queues or set update variables where possible. The application state machine ("main loop" as others put it) runs around doing the work, either...

C or Assembly -- if you had to choose only one
The question is impossible to answer simply. The discipline of engineering (whether formal or informal) requires selection of appropriate tools, techniques and materials depending...

AVR Butterfly and external storage (repost)
It seems that I can use the 4 free JTAG pins (PORTF 4,5,6,7) or the 3 free USI pins (PORTE 4,5,6); as MMC requires at least 4 lines (DIN, DOUT, CLK and CS). Using the 4 JTAG pins...
