So it's great if the same build is working on all models - thanks ! :)
32
Ok, thanks you very much. :)

Are they supposed to still work on the fx-CG10/20 ?
(I don't have it anymore)

Quote from: gbl08ma on July 04, 2017, 11:58:13 AMCan you check if my image viewer still runs fine on real hardware for both JPEG and PNG?
JPEG/PNG images seem to be working perfectly. The scrolling is so fast compared to the fx-CG10/20 ! :D

The file browser though has the same kind of graphic glitches as eigenmath :

Quote from: gbl08ma on July 04, 2017, 11:46:44 AMIt appears that the Graph 90+E uses a different VRAM address than the fx-CG50 (since on the emulator for the latter at least, the add-in doesn't show any problems).
I'd advise you not to trust the Casio emulator. Even in Graph 90+E mode apps are working, although most of them don't on real hardware.

From what I could read on http://www.casiopeia.net/forum/viewtopic.php?f=2&t=1783 , the real fx-CG50 is sharing the same problem as the real Graph 90+E.

Quote from: gbl08ma on July 04, 2017, 11:46:44 AM@critor, how do you prefer I send you builds for testing?
Email to [email protected] would be better - since I might not get the PM notification.


Thank you very much for your very prompt reply. :)

@gbl08ma  It's now summer, and back to school in some weeks. :)
May we have some fx-CG50/Graph 90+E compatible update of your eigenmath app ?

I'll gladly test it on real hardware if it can help.

Thanks for reading. :)

Thanks for your quick reply anyway. :)

Yes, we know about the VRAM incompatibilities and have started communicating about it and fixing things :

@gbl08ma Do you have the possibility to check the eigenmath app, please ?

I'm using the http://tny.im/dl/casioprizm/eigenmath.g3a download link.


It seems to be working but I'm still running into minor problems on the Graph 90+E, when I use the SHIFT+MENU menu.

The display doesn't get cleaned correctly in several situations :


And in the list-menus, the last selected item gets erased in black instead of white, making it invisible :


Wide fractions aren't drawn correctly :


And display cleaning problems too, when the history scrolls up :


No such problems with the same file sent to my fx-CG20.


Thank you very much for reading. :)

It would be interesting to see a comparison of the 2010-13 fx-CG10/20 PCB's, the 2014-17 one and the fx-CG50 side by side.

Here you are :

fx-CG20 V04


Graph 90+E

(for the fx-CG50, just remove the exam LED beside the mini-USB port in the bottom right-hand corner, and switch the position of one port Q resistor at the right of the ASIC)

Is the hardware based on 2010-13 Prizms? I hope not, because overclocking those could brick them D:

I don't remember which component you have to check on the PCB to determine this.

If you remember :

I've remade the video by adding a TI-84 Plus SE : ;)


1st : Casio Graph 90+E (french fx-CG50), SH4 @118MHz, 8MiB SDRAM
2nd : TI-Nspire CX, ARM @132MHz, 64MiB SDRAM
3rd : TI-Nspire, ARM @120MHz, 32MiB SDRAM
4th : Casio fx-CG20, SH4 @59Mhz, 2MiB SDRAM
5th : TI-84 Plus SE, z80 @15MHz, 48KiB RAM

Check the Game Boy emulation performances :


The Graph 90+E appears to be a little faster than the TI-Nspire CX, although it doesn't prove the hardware is faster since it's not the same emulator.


Same ROM used on 4 models, although the Casio version of the emulator does colorize monochrome games.
No overclocking - original CPU settings :
1st : Casio Graph 90+E (french fx-CG50), SH4 @118MHz, 8MiB SDRAM
2nd : TI-Nspire CX, ARM @132MHz, 64MiB SDRAM

4th : Casio fx-CG20, SH4 @59Mhz, 2MiB SDRAM

Too bad the TI-84 Plus CE is missing on this video, we need TI-Boy CE, it's been 2 years...

My guess is that overclocking is not going to help the TI-Nspire CX at all.
Since the fx-CG10/20 could be significantly overclocked, and the TI-Nspire CX just a little before it started crashing.

As far as I know, the problem was with Pover which performs a bad overclock.
No problem with Ptune2. :)
43
The Graph 90+E / fx-CG50 CPU runs at 118 MHz (so twice faster than the fx-CG10/20 CPU running at 59 MHz). :D

In some heavier memory-consuming situations, the new model is even more than twice faster.
Check the huge difference with the new 3D app :

(original CPU settings - no overclock)

You can already overclock with the new Ptune3 beta.
We've reached 236 MHz without any poblem so far.

FlappyBird Color is now working too, thanks to Nemhardy once again. :)

Originally, you were only getting a completely white screen.

Gravity Duck, same author, had the same minor bug : graphics ok but text outputs missing.



It has now been fixed too. ;D
Fixed Gravity Duck download : https://tiplanet.org/forum/archives_voir.php?id=905034 (single app compatible with all fx-CG models : fx-CG10, fx-CG20, fx-CG50, Graph 90+E)

The remaining non-working game apps now have major bugs, making them totally unplayable (completely white screen, or screen with text outputs and graphics missing) :

They might be less easy to fix.
