HP 15c CE - New firmware update officially available!

[ajay_m]

Well, I've spent several hours since the firmware upgrade working through the manual and the advanced features - just matrices I think I haven't yet quite got my head around in terms of memorising the keystrokes, clearly HP kind of pushed things to the edge of what they could do with the existing keyboard. Using the g key to invoke an f function is pretty weird, but as the manual states, it's the only exception, so I guess that was the unavoidable tradeoff. Just gotta remember the keystrokes now.....

I have to say the example I found in a forum elsewhere, where e is calculated to extended precision, is extraordinarily clever, using matrices to do extended precision arithmetic. Also using the random seed as an extra register (only works for numbers in range 0 < x < 1 but, still a nifty trick.

But the brilliant thing is that the keybounce problem is definitely fixed with the firmware update and of course as someone else pointed out, I can now save programs using the programming cable, haven't tried this yet but it looks pretty straightforward. It's kind of a shame that the port wasn't brought out as micro USB, which would have made things a lot more straightforward, but, hey, we have a working solution at least. [kinda wonder whether a special 3d printed back cover and POGO plug wouldn't make this possible, I have to say....]

The main thing is, it looks like build quality is superb - I really love the keyboard, which is much better than the OG 11C I also own (which works fine, but doesn't have much of a 'click') and clearly all the bugs with the LE edition are fixed. Thanks everyone for all your hard work making this device possible and then fixing the issues - I really appreciate it!.
