New firmware for the Swissmicros DM15L

[jebedeo]

Hi John, thanks!

As far as I understand the only thing missing is matrix support. There absolutely is not enough flash memory to implement that, and even if there were that would take me a while cause it doesn't interest me very much. Matrices on a pocket calculator are very cumbersome and in this day and age any PC would be way better for that purpose. For me a pocket calculator is all about speed when I am designing at my desk and need to do some quick math to see what the trade space is like. Perhaps people disagree and there is some cool use case for matrices on a pocket calculator, I am all ears.

That said, on this 15C project there is some room to improve things, especially the integrate algorithm. There might be enough flash memory left to make the step size selection dynamic, to improve performance. As Jean-Charles pointed out my implementation is slower than the 50g and that simply won't do

Other than that, I am sure there are still many bugs to be squished but in terms of functionality I think we're maxed out.

At some point I might measure current draw between the stock firmware and mine, to make sure that I am not leaving some peripherals on while idle.

As always, any input is appreciated. Thank you guys for all the feedback so far!
