ARM HP-12C devkit and cable?
Where can I find a copy of the devkit HP distributed for the ARM HP-12C?

Who can provide the serial cable or enough information to create it or something to serve in its place?

Thank you,

There was no public distribution of a devkit for the ARM-based HP-12C. However, you might contact the HP guys on this forum about that (Cyrille de Brebisson or Tim Wessman) and they might be able to email you something.


More cable alternatives are discussed here.

The dev stuff is basically just what was release for the 20/30b. The only "missing" information would be an lcd diagram.

Although I work for the HP calculator group, the views and opinions I post here are my own.

If you enjoy some diy, here is my cable/flash box solution, with schematics, pcb layout and instructions.

Have fun!

... and the keyboard mapping. Cyrille made a tiny 4 banger demo program as part of a fledgling devkit for the ARM 12c back in May 2009. I'm not sure if he distributed it much, however. Would it be okay if I sent a copy to Thomas or otherwise made it available?

Thanks,

I'd be a taker.

Would be fine to do so.

Great!

I've made it available for download here.

Also here's what Cyrille told me about it:

Quote:Attached is the HP12C+ SDK.

You will find there a couple of things:

- The source code for the 12C+ platform emulator (a PC version of the 12C+ ‘OS’ that allows to drastically cut down on the development time (since you can work and debug on PC using VC++)

- The source code for the ‘native’ ARM 12C+ platform. Normally, all your code will be in the HP12C.cpp file, which is common between the PC emulator and real product, so you develop on PC using VC++ and then you compile for real product and it works… (you need IAR to compile)

- Note that what I am giving here does NOT include the 12C+ firmware code, ie, you get a ‘blank’ platform with a ‘basic’ 4 operation calculation application.

- Some HW documentation.

I haven't played around with this in years, so probably won't be able to answer too many questions about it, but I'll do my best.

Thanks,
Katie

Curiosity or plans for a new re-purposing? Smile

Starting with a 15LE for the scientific keyboard labels?

Starting with a HP-15LE, you can hardly do more than debugging it IMHO Wink Its function set matches this package perfectly already. And its versatile LCD won't let you do much more. YMMV

There are plenty of functions that could be added without changing the layout by adding short menus to existing keys. More matrix operations are obvious, but the DSE place could lead to the 34S functions: DSE, DSZ, DSL, DEC e.g.

Stack size could increase too.

RE: ARM HP-12C devkit and cable?
With this interest, and all that room in the ARM, I wonder if someone will ever make a combination 15 / 16, with various alpha labels thrown in?

Lets see; AbCcdeFGHhJLnPU and sort of Y are possible and things like B, I & O would be obvious if used to prompt or label output, using ? and =. No way to make that beautiful angle symbol that the 41 makes, but it could abbreviate "AnG"

No T or V though. Gonna be a bunch of sad surveyors out there.

T is possible in lower case. W and M are quite nice using two adjacent digits. No good V.

Stack size could increase. For the little things I've done, I never needed more than 4 levels but my Heathkit has 5 and I'm sure it uses them all somewhere. Of course my beautiful WP 34s can have 8 levels and some folks use them. I have loaded the stack a lot to do repetitive arithmetic, and since I'm lazy; 4 is nice for me.

"See the WP 34S Smile"
I see it every day. It's my go-to calc and I like to show it off. It's getting a bit worn but that just shows it's ruggedness.

"T is possible in lower case"
That is a very serviceable t. I never thought of that.

And since we're lazy as well we've invented FILL which works for 8 levels, too. Smile

That alone could make a lot of people happy.

BTW, does the 12C+ have a working brown-out detection?

Certainly. Feel free to do it. It's just not my task to iron out HP's bugs IMHO. Confused YMMV
