Ok, but I think it is already "branded".

Equivalent to "putting a ring on it"

PS: Swissmicros may sell a few more DM15L's in the near future. A shame that their shipping is so slow (based on recent reports). Perhaps not their fault.

A user Helix reported that he was unable to stop a running program after loading firmware V33 on his DM15L. I had just installed the firmware before I saw the message. I loaded a short program with an infinite loop, started it, and I was only able to stop it using the Reset pinhole on the back. Could someone else confirm this behavior? Thank you.

It does work on the older credit card size DM15 and DM16

Very sorry, please let me clarify my earlier clarification.

Some of the very earliest DM15 devices cannot have the V33 DM15 f/w installed (IIRC, these had limited ROM size), but this does not affect all earlier DM15 cc-sized models, in fact most of them will work.

Sorry for the poorly worded comments earlier.

Update V33

Please list the program which you are unable to stop, I can't reproduce this problem with another simple looping program, program execution stops properly when I press [R/S] while running, without loss of control.

It was a simple one:
P/R
LBL A
1
+
GTO A
P/R
GSB A

I tried R/S and every other key and various combos of keys.
Gave up and Reset.
I then ran the program again thinking I might have been in some strange mode
Same result. Reset.

I've already flashed back to V32 since I use the calculator daily.
I am pretty certain that I was running my DM15L with V33 at the slower clock rate because V33 defaulted to the higher clock rate on flashing and I wanted it at the slower clock rate that V32 set by default.

I used the DM15_M1B_xx.hex images.

I used the same infinite loop program and I find it DOES stop with pressing R/S and also by pressing any other key (within limits, I haven't tried them ALL, but any I press halts the running program and shows the current count in X.

I tried with DM15_33.hex and DM15_M1B_33.hex and tried at 12MHz and 48MHz. All work normally, and can be stopped and started with R/S, and stopped with any other keypress.


Cheers,

It works fine for me too, in both 12 and 48MHz.

@Ross Barnes - please try replacing your battery and trying again. If no change, please try reflashing (with the same version V33 M1B f/w, being sure to download from the website right-clicking the filename and using "Save Link as..." to save the file.

Thanks!

I went back to SwissMicros web site and download the flash file again. I diffed it again the file use before. No differences.
I reflashed V33 M1B file. I did NOT change the battery.
After reflashing I returned the display to a single line, dropped the clock rate to 12 MHz and I reentered the program. I ran the test program and I had NO problem stopping the program. I went through a few of the gyrations I did the first time I flashed V33, changing options, etc.. I reran the program again and had NO problem stopping the program.

I then flashed my two other DM15L calculators with V33, set them up identically, ran the program and had NO problem stopping the program.

I don't know why the original V33 flash wouldn't stop a running program. The first time around I had to Reset the calculator each time before rerunning the infinite loop program using the keyboard so there must have been a problem with my original flashing of V33.

Thank you for your assistance as well as the software update.
