Thanks, could you run the attached script on your device and post the corresponding output?

It will be preferable to run the script while Plato is running and the rotation is set to 270.

I suppose I have to use ssh to do this in that case. Should I install an openssh-server on my device and then start it from ksm?
Or how else would I be able to use ssh while having plato open?

Also when I connect my device to a computer plato detects it but the computer will not detect the device but that is unrelated.

As another data point, here's how it behaves on my H2O (first of its name):

Let's start with a reference, Nickel

* Nickel:

Code:

[FBInk] Variable fb info: 1080x1440, 32bpp @ rotation: 1 (Clockwise, 90°)

* Tapping the top-left corner:

Code:

0000000    591e    5c0d    89d7    0005    0003    0039    0001    0000
0000010    591e    5c0d    89fe    0005    0003    0030    0001    0000
0000020    591e    5c0d    8a04    0005    0003    0032    0001    0000
0000030    591e    5c0d    8a0d    0005    0003    0035    0092    0000
0000040    591e    5c0d    8a17    0005    0003    0036    03ab    0000
0000050    591e    5c0d    8a23    0005    0000    0002    0000    0000

0000070    591e    5c0d    b494    0005    0003    0039    0001    0000
0000080    591e    5c0d    b4b9    0005    0003    0030    0000    0000
0000090    591e    5c0d    b4c0    0005    0003    0032    0000    0000
00000a0    591e    5c0d    b4ca    0005    0003    0035    0092    0000
00000b0    591e    5c0d    b4d4    0005    0003    0036    03ab    0000
00000c0    591e    5c0d    b4e1    0005    0000    0002    0000    0000
00000d0    591e    5c0d    b4ea    0005    0000    0000    0000    0000

----

Now to Plato:

* Plato, 270 (Visually -> UR (i.e., Portrait))

Same behavior as Nickel

. Everything okay.

* Plato, 180 (Visually, CCW I'd say, Inverted Portrait? fb origin is at the bottom-left corner).

Works properly, too.

Code:

[FBInk] Variable fb info: 1440x1080, 32bpp @ rotation: 0 (Upright, 0°)

And, as expected, touch coordinates haven't budged.

i.e.,

Code:

0000000    5aad    5c0d    9d79    0000    0003    0039    0001    0000

(except that for Plato, that's now the top-right corner. But that's translated properly).

* Plato, 0 (Matches Plato 180 Visually, but touch is fucked (top-left -> bottom-right [relative to Plato; when looking at the device, that's bottom-left -> top-right, not that it helps, since that's not the Touch orientation ;p])).

This might explain it:

Code:

[FBInk] Variable fb info: 1440x1080, 32bpp @ rotation: 0 (Upright, 0°)

fb rotation didn't take

.

Funnily enough, if I open a book, it switches back to Portrait, and when I exit the book to get back to the FM, the rotation *does* take, and everything works:

Code:

[FBInk] Variable fb info: 1440x1080, 32bpp @ rotation: 2 (Upside Down, 180°)

* Plato, 90, behaves somewhat similarly (i.e., sometimes broken)

----

By then, I think I've identified the common denominator in all this: If you switch from Portrait to Inverted Portrait, touch is fucked. If you switch from Landscape to Inverted Landscape, touch is fucked. (Doing it in the reverse order doesn't help).
BUT, if you mix'n match Portrait -> Landscape (inverted or not), everything's dandy.

----

For ref, the output of your script:

Code:

You can run the script from the KSM webinterface, for instance

Code:

/mnt/onboard/.adds/plato/rotation-test.sh

if you put the script in the plato folder.
Edit: Plato might switch wifi off, and you have to restart it from within plato

Don't worry about that: I have enough information to fix the problem.

I'll just integrate the tests into the next version.

Thanks, that's very helpful: I was quite naive to believe that a single ioctl call would suffice!

baskerville · 12-09-2018, 03:56 PM

I've attached an example of visual representation that could be used to communicate the required information.

The row of numbers under the devices indicates the read values when the written values are 0 1 2 3. On the Aura H₂O, for example, this row would be 2 3 0 1. The axes of the touch coordinates are given at the end.

NiLuJe · 12-09-2018, 04:05 PM

@baskerville: Hmm, not quite sure I understood the "image" question? That was the output from hexdump -x /dev/input/event1 after a single tap in the top-left corner (i.e., Nickel's hamburger menu), mainly so you'd have an idea of what ABS_MT_POSITION_X & ABS_MT_POSITION_Y looked like (0x35 & 0x36, respectively, third column from the right, actual coordinates in the next column).

Just for my sanity, I just checked through strace, and the ioctl pair (PUT_V/GET_F) do get fired, so that does indeed look like the device is messing with you

. (I did not decode the content, though, but I'm assuming it's correct, since that works when getting back to the FM).

EDIT: And yes, when it works (f.g., going from 270 to 0, one after the other), everything matches your Glo HD example

.

EDIT²: Err, my bad, that holds for the fb, NOT the touch axis

. My top-left corner touch example is at (61, 1026).

NiLuJe · 12-09-2018, 04:09 PM

So now I'm curious how the Forma handles that, because on everything else, I'm guessing it works by pure chance: pickel puts the device in landscape, and nickel in portrait, and I don't recall any of them doing more than one PUT_V (but don't quote me on that, stracing nickel's startup is annoying).

Please checkout the attached rotation card for your device: it should match the description you've given.

For the people interested in the mathematical details, the touch transformations for this device are:

Code:

0 → Mx My
1 → Sxy My
2 → Identity
3 → Sxy Mx

Which means that the center of the mirroring pattern is not sufficient anymore, we also need to know if Mx comes after or before Mx My (modulo 4).

The touch axes should be the same, otherwise you would have noticed inconsistencies. And the coordinates you gave for the top-left corner are in accordance with the touch coordinates of the Glo HD: x is small and y is big.

NiLuJe · 12-10-2018, 01:03 PM

@baskerville: Yeah, no, it works, I'm just confused by the direction of the axes in your graph

. The origin is indeed the top-right corner, but the inverts & mirrors are breaking my brain ;p.

The_Immortal · 12-10-2018, 08:29 PM

Guys, could you tell me please:

1. Does the recent Plato support MS Office Word formats .rtf/.doc/.docx) and F2B? Will be happy to see their support!

2. Is there instuction how to build the recent version of Plato under Windows? I found the instruction for Ubuntu only.

Thank you!

Looking at the code, it does not seem to support rtf, doc, docx or F2B. Is there a particular reason you want these formats instead of another format?

I think using a virtual machine with a linux distro would be your best option for building it in windows.
