Arduino Board as HP-IL device?

RE: Arduino Board as HP-IL device?
For Arduino there are a lot of cool extensions. If someone implements a multicolour Arduino Display like this as a primary display on my HP-41CL I would be very happy.

RE: Arduino Board as HP-IL device?
Hi Didier

I have created some kind of a manual, there you should find all details.

I also made a new sktech, with a real IL library for the Arduino and
some new features. You can change now the LIF images on the SD card with
IL commands etc.

Do you try to build your own IL drive?

Best regards
Tobie

Wonderful!! I'm looking for a small project for this summer and this looks like to be an ideal one.

Many thanks for the detailed documentation, I need now to get all the parts.

OLED displays have many nice properties, but the one in your link only has an active area of 33.6 mm by 27 mm. Aging eyes would probably need some extra assistance. :-)

Finally here is a stable “sketch” version for the Arduino Mega -> “IL Drive Emulator”

The transfer speed is around 1050 Byte/s with a HP71. (Or around 700 Byte/s with a HP75)

Other goodie :-)
It’s possible to change dynamically the current lif/dat file on the sd card. You just have to send this IL commands:
“UNL LAD01 DDL0B UNL” on a IL controller.

For example with a HP71: “: “SEND UNL LISTEN 1 DDL 11 UNL” – this will take the next file in the directory. So, your SD card can be loaded with hundreds of LIF files.

Perhaps you might consider implementing some device dependant commands to list the images on the media and also select an image by name.

RE: Arduino Board as HP-IL device?
Hi all

Software Update:
It is now possible to select any LIF container file on the SD Card with
the controler (HP41 or HP71) by name - so, there is now full flexible access :-)
A catalog function of all LIF files is already there.

Please contact me, if you like a copy of the new software.

I will check now to integrate a TFT touch display... there are displays with an integrated SD Card reader on it. Perhaps I can show
something in Allschwil..

Best regards
Tobie

RE: Arduino Board as HP-IL device?
My unit is not as pretty...but the packaging is more vintage :-)

I've put up a couple of pics of the buildup HERE.

Sorry but the comments are on the pics filenames ; I'm not very proficient on Flickr :-(

It is now my only mass storage unit for the 41 & 71B.

RE: Arduino Board as HP-IL device?
Cool stuff. I originally wanted to use a HP82163B Video interface box, but I didn't found one ;(
By the way: I used a Arduino Mega Clone for $15 instead of the original one and a MicroSD Card instead of the SD Card... made the stuff a but smaller.

RE: Arduino Board as HP-IL device?
Hallo Matthias !

Your device is very nice !

Could you share the screen model & specs ?

I use software V2 from Tobie (thanks Tobie for this great project !).

However, I didn't know that the V2 supported the Arduino screen. I will recheck the code.

For portable power, I'm currently testing 2x18650 Li-Ion charged externally.

They fit in the 82162 battery compartment but I'm not sure that would be enough to power a screen like the one you use.

Hi Etienne

Thanks for all this fotos. I like to see other Arduino builders..

There is no video supportet in the V2.

I think, Matthias meant only the CASE of the video interface...

RE: Arduino Board as HP-IL device?
Hi Tobie,

Thank you for the information !

From the picture, I thought it was a welcome screen with an emulated IL-Video Interface.

Nice device anyway :-)

When I finish testing the Li-Ion 18650 battery power supply, I will add more pictures.

Best regards

Etienne

RE: Arduino Board as HP-IL device?
Yes, a real missunderstanding.... I wantet to use the case of the HP82163B video interface.....
I'm using the newest sketch, version 14-11-09. Here the displa library was removed by Tobie (Just wondered, what sort of infos was on the output: maybe the actual LIF file with it's content.)
First I wanted to add battery supply by 18650 too, but then I found the solution with the external battery tanks you find everywhere.. They give you 5V and are cheaper Smile

Hi Tobie,

I found this wonderful project today and I`m interested in the actual software and hardware description too. Sounds like an ideal summer project for my hp71 !

RE: Arduino Board as HP-IL device?
Hi, guys!

I was thinking about such ideas on HP-IL storage devices, as I can't be confident on my cassette recorder and cassettes themselves actually.

But my direction would be other than you are trying. I would use or the cassette recorder or, even better, the card reader for interfacing with some Arduino board (Arduino nano???), as both accessories already translate all electric signals to digital ones and send them to their processors and this to storage media (circuits, motors, heads, etc).
So, I believe we should intercept the processor signals to store, read and deal with internal controls (timing, wait, read, write, etc).
The hardware is ready - well, at least the first half !!
Does anyone would like to work on such thread with me?

Best regards
Artur
