Lanczos. Tuned to the precision we were using.

Atmel AT91SAM7L128

Quote:how large is the firmware

A bit over 122kbytes. The rest of flash is used for the RAM backup and the libraries.

Quote:what development tools did you use?

Most of the development was done off device. I used Linux & MacOS. Some was done using Windows. For the firmware, we built on Windows using the Yagarto GCC 4.6.0, other versions and other compilers we tried later exposed a compiler bug so we reverted and didn't try again - if it isn't broken and all that.
