wp34s ui tweaks


I implemented several minor changes to keyboard/display interface. I tied them to enablers in features.h so default builds act as they did before.


Specifies "default" date mode, the one that is not shown when selected. I tried to set my favorite y.md format and discovered that I cannot work like that since y.md hovers in top line ALL THE TIME. So I pretty much had to switch back to d.my. You would want to change this feature if your favorite mode is other than d.my

Additionally, when DEFAULT_DATEMODE is undefined, there is no date indication whatsoever. Since datemode is something that you set once and never touch, maybe it is the right setting for some because it saves a few bytes.


When defined, changes the meaning of BEG annunciator. Now it is lit when stack size is 8 (think of BEG as BIG with typo). I found that I like the flexibility of 2 stack sizes, but most of the time I want to use 4 levels + 4 easy to access registers a,b,c,d. So when some library program (or myself) sneakily changes that, I want some visual indication.


When defined, modifies meaning of [h] [./,] in DECM mode. Instead of changing radix symbol it turns on/off thousand separator, similar to INT mode.

Here is the patch (preserves original settings). Would you please incorporate it into build?

Incorporated but all turned off.

I modified the data behaviour to not allow the display to be excluded. I.e. undefined is as before this patch.

Uh-oh. That was actually the mode I was going for. I personally find datemode indication way too intrusive. Even when I want to temporary switch to non-default mode, I do not want those constant reminders.

Would extra feature "#define NO_DATEMODE_INDICATION" be more in line with the coding style?


Andrew, I'm with you here. The mode indicators in the pixel area are quite intrusive. I don't mind them in binary mode but for one time settings I'd like an option to hide them.


You could always compile with

uncommented (in features.h) and then, after setting Flag J, you'll have the y-register displayed instead of the date format!

why flag J, why not flag Y?


I chose Flag J because it's on the x<->y key (not entirely logical, but good enough for me!). I didn't choose Flag Y because I think of it as one of the user flags that people are likely to use in their normal programming. The WP-34s has an awful lot of flags, of course! Clashes are probably unlikely whichever flag is chosen.

I've added the NO_DATEMODE_INDICATION option to features.h and it is disabled by default.

I do agree that the date mode indication is a little intrusive, however the few times I do change it, I definitely want to know. It is more important to display this than degrees/radians IMO. At least with degrees vs radians I've got a feel for the kind of answers to expect and realise the error quickly. Degrees vs gradians would be a problem however, but I never use the latter.

The D.MY default was an easy choice. By far the majority of countries and the world's population use this format. That it also covers all of the principle authors made the choice even easier :)

Pauli, thanks.

For the record, I did not question the validity of d.my as THE choice for standard default setting. However, from my point of view it is only slightly lesser abomination than m.dy, so I appreciate an option not to use it.

Also, I think that rad/deg/grad indication is adequate. I agree with you on principle, but somehow, internet is full of posts "how comes my calculator gives me garbage for an answer?" immediately followed by "figured it out -- radians mode". Maybe, if I ever use grads, I will start thinking that hovering g is intrusive, but not today.


For the record, please see p. 47 of your printed manual. We'd have appreciated any opportunity for a smaller indication but had to accept the display as it is. Writing this, however, the following idea crossed my mind like a neutrino: how about using a subscript Y instead of y.md for indicating the second widest spread date format? Would be really tiny.



We don't have a spare character in the character set for a subscript Y.

Hmmh, I see a subscript Y on my WP 34S.



Guess I'm blind at the moment :-(
