New firmware for the Swissmicros DM15L

[jebedeo]

Hi guys,

Another beta with some bug fixes:

1.

Quote:The only thing I would like to see fixed is the case of entire powers of negative numbers.

that should be fixed now, but give it a stress test!
2. Very small numbers are now displayed properly until they becomes zero. Earlier versions of the firmware had weird behavior with stuff smaller than 1E-318 or so
3. The quirks with very large numbers that John pointed out is also fixed, thanks for catching it!

Quote:I think now that this firmware deserves a more suitable hardware than my small DM15, and I will purchase a DM15L next year just for it.

well that's a compliment!

Another things that I still have to fix is that sin(180) is not 0 but some E-16 small number.

As you might notice the firmware is lighter than before, there are some extra 4kB available now!
I copied the math library into my source code rather than using the already compiled code that comes with the compiler, and that means that there is more room for optimization at compile time, hence more memory savings. The speed seems the same if not a touch faster, at least based on some of the benchmark numbers that John posted a while ago.

Thanks again!
