Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Miguel,

 

I think it's important to precise that all of this is absolutely not official.

Perhaps these specs are true. Perhaps not ... At this stage, it's only rumors. The only official annoncement is the video and noting on specs inside.

Hi!, all:

 

The first program, of Fractals, for HP PRIME GRAPHING CALCULATOR, from ... http://www.calc-bank.com/

 

BEGIN
LOCAL iter := 0;
LOCAL z := (0,0);
WHILE (ABS(z) <= bailoutValue) AND (iter < maxIter) DO
z := z*z+c;
iter := iter+1;
END;
RETURN iter;
END;

LSclr(Ndx)
BEGIN
Ndx := ROUND(Ndx*186,0);
IF Ndx < 31 THEN RETURN 0+ 1*Ndx; END;
IF Ndx < 62 THEN RETURN 31+ 32*(Ndx-31); END;
IF Ndx < 93 THEN RETURN 1023- 1*(Ndx-62); END;
IF Ndx < 124 THEN RETURN 992+ 1024*(Ndx-93); END;
IF Ndx < 155 THEN RETURN 32736- 32*(Ndx-124); END;
IF Ndx < 186 THEN RETURN 31744+ 1*(Ndx-155); END;
RETURN 31775;
END;

colorize(itVal, maxIt)
BEGIN
IF itVal==maxIt THEN
// We are inside the Mandelbrot map
// Then the pixel is drawn in blackRETURN 0;
ELSE
RETURN LSclr(itVal/maxIt);
END;
END;

EXPORT Mandelbrot()
BEGIN
// Clean the screen (G0):RECT();

LOCAL dx, dy, c, xp, yp;
LOCAL iter, color;

// These 4 variables defined
// Our window of the complex plane

LOCAL xmin, xmax, ymin, ymax;
LOCAL maxIterations := 50;
LOCAL maxRadius := 2;

// Location
// Radio width to height should be 4:3

xmin := -2.5;
xmax := 1.5;
ymin := -1.5;
ymax := 1.5;

// Other parameters better:

//xmin := 0.315625;
//xmax := 0.515625;
//ymin := 0.28125;
//ymax := 0.43125;

dx := (xmax-xmin)/320;
dy := (ymax-ymin)/240;
c := (xmin,ymin);

// we loop over each pixel
// Of the screen wil Prime:
FOR yp FROM 0 TO 239 DO
FOR xp FROM 0 TO 319 DO
// Create the complex number c
// We need for iteration:

c := (xmin+xp*dx, ymax-yp*dy);

// Now iterate the formula and
// Return the number of iteration steps
// That was taken up
// That the complex number jump out
// The radius of convergence:

iter := iteration(c, maxRadius, maxIterations);

// Determines a color for the iteration number:color := colorize(iter, maxIterations);

// Change color to that pixel:

PIXON_P(xp, yp, color);
END;
END;

// deja la imagen en la pantalla
// hasta que se presiona una tecla:
REPEAT UNTIL GETKEY() == -1;
FREEZE;
END;

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

[ Edited ]

The lack of comments here surprise me.

 

Anyway, I kinda hope this is just another (but more high-end) student calculator?

 

Of course the main market will always be in education, I understand that, I just hope that this 'HP Prime' is not intended as a complete replacement for HP50G?

 

As a calculator, as in a math companion in professional and private life, HP Prime disappoints in a couple of manners:

 

Touch screen instead of soft menu keys.

Custom hi-energy battery + charger.

 

 

I understand that the backlit color display is a sales argument in some circles. But to me, it's far more important to have low battery consumption and not to have the hassle with a charger, or have to worry about the condition and health of a very-hard/impossible-to-get, rechargeable battery. That we're supposed to be used to this from smartphones, is not a good point. 1: I hate my phone. 2: I can replace my phone at seconds notice, because it's a mainstream commodity. Calculator is not.

 

My life with HP28S, HP48G, HP49/50 has been extremely heavy on the soft menu keys. This is how I mainly operate the calculator - from my tree of my own custom menus, which link to my own custom functions, but of course, the calculators many own functions, buried deep in the menus, as well.

Will you now tell me a touchscreen will be a reliable and convenient substitute?

 

I'm sort of fine with the HP50G.

The system and CAS need an overhaul to become modern and take advantage of more capable addressing. But what I mainly ask for, in a replacement, is: Faster - Better display (monochrome&passive is still superior to high battery consumption) - A better ENTER-key - And maintenance, (which the HP50 has lacked for a long time, apparently because HP-calculators have given priority to new foundations).

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Hi!, Vermagster:

 

How about if we wait until the month of September, which is, the final release?.

What of the lithium ion battery, is a good option and also touchscreen. Look, I have two Smartphone HP iPAQ 910c with expand 5VDC and 3840 mAh battery, touch screen (never failed me and it's been over two years than I have), 400Mhz processor and it is, wonderful. The brightness, the HP Color PRIME can be mitigated, as in my Smartphones, to avoid excessive consumption. If you have no charger and batteries be removed, it is also an advantage and also besides making it, from a 110/220VAC, you could load it from the 12VDC power supply of your car.

Hi, Miguel.

Thank you for your response. Yes, we must wait until September. But I'm sure it will be well received. I think those features which I don't like - charger and absence of soft keys - will not bother the market which the calculator is aimed for. It is likely that they will appreciate the backlit color display and touch screen more. And I have no problem with that.

 

Regardless, for the best chances of seeing a suitable calculator becoming marketed one day, it's probably important that the HP39GII and HP Prime do well.

I think the touch screen could be nice ( and you have 'really' soft menu :

The battery is necessery with a color screen.

 

But it s difficult to have a definitive  opinion without testing...

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Hi!:

 

IMHO, I think if HP, has decided to include, a lithium polymer battery rechargeable, is because it is the best option today and has tested conveniently. I know with, my two Smartphone HP iPAQ 910c, with expansion batteries of 3.7VDC and 3180mAh. Logically that HP PRIME, will have a timekeeper, to turn off automatically as does, the rest, of the above calculators.

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Thanks for posting this. Where can I learn more about this language? Is it compiled for the 400 MHz ARM chip? What other graphics commands are available? Is double buffered animation possible? Can I place an input button anywhere on the touchscreen?

Hi!, twixtfanatic:

Welcome, to site!.

The Advanced HP PRIME GRAPHING CALCULATOR, isn't available today. The Programation languages are RPN, algebraic and other what IMHO, is similar to Pascal Language, but, i'm not sure. Wait a few days, for more information.

There is no RPN programming of any kind. RPN operation and entry yes, but not programming.

 

For information about what the language looks like, see the 39gII users guide. It is very similar. I'll stick the extracted chapter here for reference.

Hi!, Tim:

 

In the data sheet, what you can see, in my other post, indicate ... RPN.JPG. With this specification I suppose the possibility of programming, in RPN.

You have more chance, for obtein information, why you work, in HP calculator's group.

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Thanks for posting the chapter. This Pascal-like language is edited and evaluated on the calculator itself. It surely is not compiled directly for the ARM chip. So, it can produce beautiful graphics images, but it isn't nearly as fast as the calculator could be.

 

At hpcalc.org is the package hpgcc for the 50g. This allows the user to write a C program on his/her PC and compile it there for the ARM on the calculator. The result is often orders of magnitude faster than a similar program in user RPL would be. hpgcc is maintained by volunteers who have to deal with changes to the gcc compiler and many other issues while keeping their day jobs. It never gained the popularity that similar software for the TI calculator has achieved.

 

Now that HP has a new machine, with a connectivity kit, wouldn't it be great if third party developers could write in some high level language such as C or Pascal, with system calls to access calculator memory, display, and input, that would compile for the ARM chip? A GUI app for my Linux machine, with an emulator and an ARM back-compiler, which could transfer wirelessly or by cable to the Prime: is that too much to ask for? Chop chop!

Hi!, twixtfanatic:

 

You have to wait, for September, when it goes, on sale. I have accurate information that will be important news in July about his performances. I know I have a lot of information ARM microprocessor, which take this gem, as above, will be of great technology.

 

For the microprocessor, you can see for comparison, the heart, of HP39GII (ARM926EJ-S, of Family STMP3770) ...Hearth fo HP39GII.JPG and the specification, of the comparison table, from ...

http://www.freescale.com/files/32bit/doc/support_info/STMPFAMCOMPTBL.pdf

 

And ...

1) ARM GCC Inline Assembler, from ... http://www.ethernut.de/en/documents/arm-inline-asm.html

2) In the attachment file, in clip, the ARM Assembler Guide.

 

Too, the Manual of Assembly for ARM926EJ-S, downloaded from ... http://infocenter.arm.com/help/topic/com.arm.doc.ddi0198e/DDI0198E_arm926ejs_r0p5_trm.pdf

 

 

Note: IMHO, the HP PRIME, will be equipped, with the same or, similar microprocessor.

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Thanks for this program.  I'm trying to run it in the HP Prime emulator, but it complains about an error - is the first line missing as the listing here starts with BEGIN which I'm not sure is legal?  Shouldn't there be a function name first?

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Actually there are many things wrong.  Besides the missing 1st line function name, the variables bailoutValue, maxIter, c are not declared and give syntax errors.  I stopped there.  Any chance of a repost of the listing, so that it can be pasted into an hp prime emulator program and run?

thanks

Hi!, tcab:

 

Welcome, to Forum!.

 

This is an illustrative example, of use maxIter and Bailout values, of Fractals, will come better explained when you leave in September or October the Advanced HP RPIME GRAPHING CALCULATOR, in your User Manual. Be patient.

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Does the Prime allow execution of user programs or functions in RPN mode? ie. Taking & returning values or symbols via the RPN stack? Without this capability it would seem RPN has been mortally wounded.

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Miguel,

I received my Prime calculator a few days ago. I have barely got my feet wet.

One thing I noticed, the MATH TEMPLATE (shift-9) does not contain the derivative, the integral symbols. Instead you need to get them from the SHIFT-CHARS,MORE,MATH OPERATORS view. A little inconvenience.

As stated, you should look at the template key.

 

The key you are looking at really just contains some characters that get used in some types of match (engineering primarily). The functions are on the 2d template key that has the alpha "C" on it.

Re: HP PRIME GRAPHING CALCULATOR - Technical data and performance comparison with others.

Miguel and Tim, thanks for your response.

I know about the math template (the C button). I was trying to locate the derivative, the integral, substitute and etc symbols which are all scattered in the shift-Chars displays. If you hit, shift-Vars (Chars), touch the MORE button, scroll up to the MATH OPERATORS and touch, the partial derivative symbol is just to the right of the hilighted symbol. The integral symbol is also in this character set. Just an observation.
