No x11, first seen in K4 diags system IIRC.
I am not even sure if the K2 supports DirectFB.
We may have to draw a new screensaver.png every minute.
And with a iMX30, we may have to start drawing 30 seconds before hand.

@NiLuJe:
And if not, we can draw as 8 bit, and imagemagic it down to whatever is needed.

@brianinmaine: No WM, no X. Have to talk to the fb directly.

EDIT: Argh. Missed a new page once again

These old devices do represent a challenge.
But since idoit also wants things for his (2.5.8) DXG ...

- - - -

If we only need Cairo - the binding library I gave earlier is the better (and maintained) one.

Of most interest are the worked examples in: oocairo.orig.tar.gz

I hope this link starts to work from everywhere in the world.

Because not the linked to, next to last, example but the following, last, example is probably more of interest.
Code at: http://java-gnome.sourceforge.net/do...inedPaper.html

There you'll see how the doodle of a tank (as a png) is overlayed on what is already written on the surface.

K2 devices don't have a lot of processing power, but for a clock, we can use pre-rendered textual parts (not unlike what matchbox-keyboard does for its keycaps).
See: loading-images.lua in the cairo archive above, examples directory.

We would need (rendered in desired font, saved as *.png files):
A 12 item array of month names -
A 7 item array of day names -
A 2 item array of day part name (AM, PM) -
A 10 element array of (properly kerned) digits -
A colon -
Ah, I think that is all that might be found on a clock face.
Oh, maybe a rendered background pattern.

clocktab site uses a table to align the parts -
We could use a pre-computed table (the only datatype that Lua has) of component coordinates -
call 'date' with a custom (easy to read) format string -
read the parts of the string -
lookup that part's coordinates and png -
read to pix buffer, set as those coordinates -
write the whole thing to a *.png in /tmp -
make an eps call to display the png -
go back to sleep.

I am thinking that even a K2 could do that every minute.

knc1 · 09-04-2015, 10:18 AM

Assuming we will only need Cairo (since we will be loading already rendered png rectangles) - -

The collection of (matching versions) of source code is attached for the whole project.

Yes, they date from 2011/2012 but that is more recent than the K2.

If your on x86 Linux or Windows, the cairo binding zip has already built binaries.

Otherwise - we just need to build this stuff to be run by an iMX30 from USB storage.

Oh, and provide a Lua script to implement the K2-Clock.

Note1: Going this way, Kindle-Clock can be ported fairly easily to all models.

Note2: This **is not** the lua binding from Debian, its the better one from:
http://www.dynaset.org/dogusanh/

Isn't Open Source just great?

Sorry I didn't say so earlier, the link did start working again. I guess the website was just down before when I tried to use it.

Just think of Lua as Java stripped down to its simplest possible implementation - you'll have no trouble with it.

The various archives I have attached have a lot of examples (from which code can be lifted).

- - - -

Grumble, grumble, grumble - - -
The only serial port information linked to in the K2 prefix index turns out to be a K1.

Here is hoping the K2 is like its big screen cousin, the DX/DXG

My bad, iMX31 (never was such a thing as an iMX30).

Target cpu: ARM1136JF-S (a.k.a: ARMv6)
See attached reference manual.

This post may grow to include the binaries required.
All except that "script to implement" - that will be up to space_escalator.

If I am successful, these binaries should work on models K2 .. KV.

knc1 · 09-05-2015, 01:34 PM

Hmm...

Cairo requires Pixman -
Pixman seems to default to ARMv7 (with newer arch options) -
And we have an ARMv6 device.

Grumble.
this might take a bit more than: ./configure; make ; make install

space_escalator · 09-05-2015, 03:35 PM

Hooray for YouTube! After an hour-long video I am ready to delve into Lua. Alright!

space_escalator · 09-05-2015, 04:17 PM

So I installed cairo via homebrew by entering the command
brew install cairo
I hope this was the right thing to do... Oh well.

Also, I'm about to start making all of the .png's for Roboto Condensed using screenshots of TextEdit for lack of a better tool. Should work alright as long as I pay attention to the coordinate numbers.
Edit: png's complete. Font size 144 seemed large enough.

space_escalator · 09-05-2015, 05:49 PM

Ugh I feel like a toddler who can't do anything for himself. I've installed lua, but I have no idea how to properly install luacairo. The website has binaries for Linux and Windows, but not Mac. I downloaded the source and tried the 'make' command because I found a makefile, but it just gave me errors because it couldn't find lua.h Furthermore, all help about missing lua.h files suggests lua developer packages in linux.

Is now the time to boot up virtualbox and work from inside Linux? What should I do to get cairo working?

I can not help with that, I have never used a Mac.
And, I am certainly not a virtualbox on Mac user.

Why not use any of the hundreds of Linux LiveCD's?
Pick one that lets you store your work on a removable flash stick.

The LiveCD list has hundreds to choose from, but try (available even if your Mac is ppc):
https://livecdlist.com/lubuntu/
That should either run as a LiveCD or be what you use to install it into a VM machine (if such things let you install from a CD).

First days effort (built, haven't tried any of it to see if it runs) -
All built ARMv6, hard float, fpu=vfp2, optimized for speed on the ARM1136, and built against the musl libc.

Still need to build the Lua bindings for libffi and libcairo -
Also fix fbset problems (which looks like a missing header file):

The general plan there is to (other than suppliment a bunch of Amazon 10 year old code) -

Parameterize the clock layout and the font rectangles in json -
Generate the font rectangles for the clock (once) on the Kindle -
Have whatever might be needed to diddle the framebuffer, public time network, hardware clock, fonts, and a kitchen sink worth of other things.
