WP 34S Printing



#17

Do I need to activate printing somehow? I have tried with revision 2896 but it doesn't work. I don't even seen an announciator (should be "=" right?)

Where am I going wrong?

Cheers, Harald


#18

Do you mean on the real calculator or on the WIndows emulation?


#19

On the real calculator.


#20

Well, then I can't help much. :-(

But it should work as soon as you execute any print command, there's no print ON/OFF switching.

And you have flashed with calc_ir.bin I hope ... ;-)

Edit: now I'm just not sure if you won't even need an timer chip (XTAL) in your calc for printing - IIRC I've read this anywhere!?

And there's a command [print]? which should return "true" if the necessary hardware for printing is available.

You have helped enough already. I assumed calc_full would do the job as well. I will try with calc_ir.

Thanks,
Harald


#22

The _full moniker just denotes the presence of the user code library in the image.

We decided, for the sake of binary compatibility, to include the printing commands in the default image as NOPs. Printing needs the crystal, at least I'm believing it, and is heavy on flash space, so it's not included in the default build.


#23

Sorry, I typed too quickly. I meant calc_xtal_full....
I am about to re-flash and will report later....


#24

The _xtal builds contain the stop watch, another flash hungry feature. We cannot yet afford to include both.

#25

Yippie! It's allive!

Great job Marcus! Shame that build looses the Stopwatch though. Any chance we can have that back?

Oh and another thing: I had no succes reflashing the 34S using my integrated USB interface. Is it possible that ON+D, ON+S+S, reset, ON doesn't properly activate the bootloader anymore? MySamba seams to be succesfull, but after flashing, resetting and turning on the calculator it displays "restored" and still contains the old firmware.
The erase and rest procedure on the cable works.

Cheers,
Harald


#26

Oh, you already answered the question about the stopwatch above.

#27

I flash trough USB with a modified cable so in theory it should work with yours. If you do ON+D, ON+S+S, ON, and the calculator does not return to normal, the boot loader is active. MySamba restores the boot bit before it attempts to flash anything. This was a hack needed to make MySamba compatible with images shorter than 128KB. If you see MySamba succeed you can mostly be sure it has reflashed the device.


#28

Hi Marcus,

I have tried two different ways of flashing. One works, and the other one doesn't. Both use my integrated USB adaptor to connect the PC to the 34S.
Using ON+D, ON+S+S, reset, ON, then flashing, reset, ON results in the calculator displaying "restored" and the firmware NOT being updated. However MySamba transmits and tells me it took 24s (as usual)
Following these instructions:

Hold down the ERASE button on the cable (do not release it).
Press and release the RESET button on the cable.
Press and release ON/CE on the calculator to turn it on again.
Release the ERASE button on the cable that you pressed a few steps earlier.
Press and release the RESET button on the cable.
Press and release ON/CE on the calculator. It will not appear to turn on.

followed by flashing with MySamba (again tells me it took 24 seconds) is succesfull. After reseting and turning on the calculator it comes up displaying "erased" and contains the new firmware.

I suspect I am making a mistake in my ON+D, ON+S*S.... procedure, but can't see it. This has worked for me in the past. Am I missing a step?!? If not, the only thing that is different is the firmware.

It is almost as if the SAMBA bootloader is active, but just dicards the data instead of writing it to flash.


#29

Sorry not being able to help you. Your key sequence should work and seemingly does, except for the strange outcome. Maybe your unit has a fault. Can you make a RAM backup to flash (ON+STO)? Does it really update the backup area? Can you update the library with PSTO or CLP ?

Maybe you can help me.

Where does the printed output go in using the emulator? Or does it go anywhere?

When I execute the "Print Program" function, I can see the emulator chug away and the "=" annunciator blink, but I can't seem to find any output anywhere.

TIA,

Les

I hope. ;-)

You need the HP82240B Printer Simulator from Christoph Giesselink:

http://hp.giesselink.com/hp82240b.htm

After you have installed it start the program HP82240B.exe and set the Graphic Scale to 1x or 2x (not absolutely necessary, but many special graphic symbols aren't displayed correctly in the usual ASCII window).

Then you see any print output from the WP34s in this Printer simulator window.

Thanks! Works beautifully.
