USB OTG Mouse Support and page turn on PW3(possible KV/KOA)

[geekmaster]

Maybe a mouse will get me past issues I have when my PW3 touchscreen is not working. I need to try this after I recharge my PW3. I wonder how hard it would be to make it act like a mouse rather than just page tuen buttons...

It's possible and shouldn't be difficult, just config it like other Linux distro. Maybe add section below to /etc/xorg.conf

Section "InputDevice"
	Identifier     "Mouse"
	Driver	         "mouse"
	Option        "SendCoreEvents" "true"
	Option        "AllowMouseOpenFail" "true"
	Option        "Device"       "/dev/input/mice"
	Option        "Protocol"     "ImPS/2"
	Option        "Emulate3Buttons"  "true"
	Option        "ZAxisMapping" "4 5"
EndSection

However if anything goes wrong X may fail to start so I never tried that myself as I don't have serial on my kindle.

You will, at a minimum, have to re-start X, since otherwise it is self-configuring and can't self-configure for what is not connected (kernel modules, otg cable, mouse).

Thanks, you're right, can't edit /etc/xorg.conf directly. xorg.conf was created from /etc/upstart/makexconfig which is just lots of "echo >>" inside so its actually pre-defined.

There is no mouse driver in /usr/lib/xorg/modules/input/, does have an evdev driver and kernel has evdev support though.

To restart X, just run "restart x" from ssh or kterm, however even with mouse plugged in it was not detected/added to xorg.conf.

That actually makes it sound like it would be easier to get full mouse support.
Just have to dig a little deeper into the system than change a configuration file is all.

This is great, I'm super excited by this.

I don't know what kind of HID device this is for sure, but something like this would be great ( Presentation remote )

also, zxczxc found that just changing the pages wasn't necessarily enough to keep the screen awake in this thread:

But I'm actually looking at the strings in your 'mouseturn' program, and see you already had that covered "lipc-set-prop com.lab126.powerd -i touchScreenSaverTimeout 1".

I cant be bothered to discard this comment, if other people work on things like this.

I don't have any of these but looks like these remotes are HID keyboard devices -- and additional HID mice if they have cursor control. To get buttons work, load hid modules, get key code with "evtest" utility and respond accordingly.
The code should be very much like the one in "wifiremote" android side and it's fairly straightforward.

Current "mouseturn" relies on mousedev and /dev/input/mice interface so it requires little extra work for end users, however, it wouldn't work with evdev.

@lucida, would this code be good to start from in order to turn pages automatically at regular intervals (without monitoring any mouse/usb data)?

i want to turn the kindle into picture-frame like display, that rotates through pages (preferable pages of a pdf).

then i want to change the page selection to be random, and finally change the duration between changes to be random (from a few minutes to a few days).

and it sounds like i still need a solution to keep the kindle from sleeping, right?

so you are saying if I wanted to use something like the item below, it wouldn't be too much work, and to look at wifiremote to get the idea? sounds good!
because I have decided on this item.

(this, like many other presentation devices use page up/page down for navigation, simply a keyboard)

Try this. the first /dev/input/eventX is the OTG device(not kindle), then a list of button keycode and coordinates of point.

	kindle-evdev /dev/input/eventX btn1:x1,y1 btn2:x2,y2....

You can start by running

     kindle-evdev /dev/input/eventX  1:1,1

from ssh/kterml, check the output to get keycode.

lucida, thanks.

I'm looking at the source of this, and I noticed something all of us should keep in mind, that I noticed with my version:

If we use simple clicks, we could click links on the table of contents and the like.

I don't know if other people are using the bottom pixel or something else.

So I feel like we need to really do a 'swipe' effect if its possible with the x11.

Also:

To compile this, did you need to get any particular x11 libraries, or can you otherwise talk about your build environment?

I have tested out both your mouseturn and the kindle-edev you provide with this:

https://www.amazon.com/Rii-Wireless-.../dp/B006WAJ1IE

And both the mouse and keyboard parts work.

The keyboard device only seems to show up if I also insmod mousedev.ko, and I'm not sure if thats expected right now.

Its nice that I can use this for both mouse and keyboard in event2 and event3 if we wanted to.

I used the 'report incorrect product information' button on that page to let them know they forgot to include the 7th gen Kindle Paperwhite in the list of supporting products.

Too bad it isn't an Amazon product, that would probably have really jacked their jaws.

@lucida

How is your system set up to link against libXtst.

I have been trying to compile using hte cross-compiler I have, and have not been having luck.

do you have the armel setup instead, or can you give any makefiles or anything that you can share?
