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

[Yourcat]

A KUAL extension is a 'standard' package so the idea is fine. If one really wants to use a Kindle with a broken touch screen following the manual instructions shouldn't be too hard. A u-dev rule would be indeed nice. I hope that it's easy to implement.

Since you made a KUAL extension, you probably have a script already written to do the setp -
Just call that script from your new custom u-dev rule.

Why not add a u-dev rule that installs the external mouse handler when the external mouse is plugged in?

yeah, In hindsight that didn't make a lot of sense.

Right now i'm at the point where my script
Loads the .ko modules
mount --bind to a custom makexconf and cursor
restart x

I have seperately my program that refreshes the cursor on the screen that needs to run as a daemon ( its not daemonized yet )

I was next going to try to use /dev/uniput to create a "mouse" thats active wether or not an actual mouse is connected.

This is becuase xorg.conf apparenlty cannot respect hotplugging evdev devices, it needs to have /dev/input/eventX thats active at the time it is restarted. And if you ever unplug it, you need to restart x after its plugged in again. the PW implementation alo won't load the "mouse" driver, to use '/dev/input/mice'.

The idea there being that the daemon 'pointer.c' would be able to detect a real mouse plugged unplugged and clone all the events into /dev/uinput, opened up, so that whenever the daemon is running, there will be a mouse, it just won't generate events unless an actual mouse is plugged in.

( I dont want to force an x restart every time the mouse is plugged in )


leading to a final script that looks like:

load hid.ko and friends
start daemon with
bind makexconf and cursor ( based on device - or patch makexconf instead of harcoding )
restart x


for the cloning, this code might be something to look at,

Does anyone have any good info on udev, where rules live on the kindle or otherwise?


The refreshing program is based on xrefresh.c: http://opensource.apple.com//source/...0.2/xrefresh.c

Mixed with a program called hhpc: https://github.com/aktau/hhpc/blob/master/hhpc.c

From hhpc I took the code that eavesdrops on all mouse movemnt events, and then passes them along to where they should go.

From xfrefresh I took the actual refresh part - open a transparent window over the whole screen, which will redraw the mouse ( when I had it only drawing over the cursor location, it would leave multiple cursors )

Check this code for generating uinput from input_event.

http://www.linux.it/~rubini/docs/inp...udpmouse-get.c


kindle's udev rules are in:
/etc/udev/rules.d

/dev/input/mice is not working because the required driver(mouse_drv.so) is missing in kindle

/usr/lib/xorg/modules/input/


Maybe build one and put to kindle? seems easier than the daemon approach.

What I meant by this is - if you try to set up xorg.conf with a configuration entry of type "mouse", instead of "evdev", the log states

"<some thing I can't remember from memory but is like AllowEmptyDevices is turned on>" - "Disableing drivers of "keyboard and mouse"

And when I turned that on, it also said another message, and disabled the drivers of "keyboard" and "mouse." I can get the full error messages tonight.

but they could be because the xorg drivers don't exist, yeah.

This daemon could make the keyboard work to, since there's no match for /dev/input/keyboards like there is /dev/input/mice

Here you go, give this a try:
in mouse.sh, go ahead and adjust your paths.

And if you need to, adjust your makexconfig to have the touchscreen from your kindle if it is different.

Also in makexconfig, the mouse is hardcoded to /dev/input/event3 - because I have a keyboard/mouse combo, and the keyboard mounts first, so if you have a mouse only, you may need to change that to event2

the source is in here, the tweaks to be made are the size of the refresh window ( default full screen ), and the refresh frequency ( right now, after all mouse events are consumed )

Nice work!
Thanks for sharing

You are my hero :-) I am following this thread with bated breath. Now to find an old wired keyboard lying around (and figure out why my battery keeps shutting off when connected to the otg hub.)

My hope is to connect the keyboard so I can use the kindle as a low power writing source in the sun. Thank you for pursuing this project and I hope to help contribute once I find that last wire...

Did you keep instructions on setting up their crosscompiler with kernel?

If I'm going to try to write a kernel module, I figure I should use thier source tree.

When I just tired on ubuntu, I got the cross compiler to go, but trying to compile the kernel gave some missing header files.

drivers/power/bd7181x-power.c:28:18: fatal error: llog.h: No such file or directory
#include <llog.h>

I also have the kernel from 5.8 ( 3.10.53 ) instad of 5.7 ( 3.0.35 ), though I don't know enough about kernel modules to know if thats an issue long term. I'm going to go get that source tree and start woking on it

You will have to build the module for a specific kernel(s).

Use 5.8.1 source

Kindle_src_5.8.1_2974910023.tar.gz


The 5.8.2 source code is for KindleBasic2 only with a 3.10.53 kernel, but Amazon released it for all 5.8.2 devices.

All other iMX6 devices(PW2 to KOA) are still using 3.0.35 as of firmware 5.8.2 so just use 5.8.1 source which is correct and has llog.h included.

ah,thanks.
I did grab 5.8.2 source, not 5.8.1, I'll check that out.

Works on my PW3 5.8.1 and 5.8.2.

Lucida! This works marvelously well with all of the mice that I have attached to my PW3 5.8.1 - thank you.

Now I just need to get my toolchain up and running and do the same with a keyboard module (unless someone has already done that). Coplate?

lucida's attachment here should work for mouse and keyboard

It just needs to know what device to point at ( /dev/input/event1, /dev/input/event2, etc. ) and which keys you want to trigger it.


I'm still working on one that would support hot-swapping, but I've been distracted by World of Warcraft's Legion invasion.

It still needs the hid.ko and everything from the starg-otg.sh scripts, but it would replace the './mouseturn $(./config.sh) &' line, with one that points at your device and button configurations.
