Send touch event to screen / flip page from shell

peterson · 11-27-2015, 11:00 AM

Hi all

I am looking for a way to flip a page automatically. I.e. let's say I connect via usbnet to the Kindle, is it possible (on a Paperwhite 2) to issue a command that will go to the previous / next page? I can't seem to figure out how to get the X11 server or the Amazon software to think that a touch happened.

TIA!

The info is here, somewhere (but probably for an older model).
Someone needed to do that for a handicapped interface.

I haven't found it for touch devices, only for devices with buttons where you could type "echo send <keycode> > /proc/keypad" to enter a key. This does not work on the PW2 (/proc/keypad does not exist) which does not have any buttons except the power button.

Okay, I widened my search and found a solution for the Kobo that works on the PW2 as well:

Record the touch by:

cat /dev/input/event1 > touch.txt
performing the touch on the device (keep it short)
ctrl+c

Play it back by executing echo touch.txt > /dev/input/event1

The touchscreen is not always /dev/input/event1 on all models/all firmwares.

Someone wrote about that here also.
Plus, perhaps, how to find which event device it is at runtime.

Forums are great, esp. this one - learned so much. However it is a big pain to find anything in large forums as the search will almost always bury the good threads/posts under an avalanche of "I am trying to do ..." and long discussions that already require a lot of background information (or are simply useless). As I mostly use my Kindle for reading and only hack on it once a year, I tend to forget many details - and am unable to find them again. Point in case, it took me (only) 15 minutes to find the USBnetwork package for PW2 (or rather I found the one for Touch/PW1 though when downloading it there's a PW2 version).

Anyway. Sorry for the rant. Spent half the day searching for stuff ;-)

For now I will assume that on my particular PW2 and never-to-be-updated-firmware the event device will stay the same :-) I could not find another post mentioning using /dev/input/eventX for Kindle, however I found https://github.com/koreader/koreader...dle/device.lua where the correct device is listed for many Kindle devices. I will revisit this issue if I manage the actual goal (remote controlled page flipper, so I will either need to get USB OTG working, or find the internal USB host, or get bluetooth connected to the serial port).

RIGHT!
It must have been the KOReader source that I was thinking about.

- - - - -

We do have a (hidden) advanced search -
In the top right corner of any page, there is an input box and a 'search' button -
When logged in, leave the input box empty, click 'search' -
Bingo - a pretty fancy advanced search thingy.

- - - - -

We have the ability to filter the thread index by prefix.
That is a fairly recent (2 years or so) addition.
If you find something useful in your searching that does not have a prefix assigned -
On the first post of the thread -
click 'report post' -
in the report comment box, request that a mod assign an 'xyz-whatever-is-appropriate' prefix. (your choice, pick one).

- - - - -

We have an index system built of Wiki pages, per prefix - -
If you don't find what you need in the index -
Add it when you find it.
(You don't need to be a member of this forum or the wiki to add things.)

Lots of examples of how to code the links.
Its a Wiki, don't be concerned about 'messing it up' - like any wiki, the contents are versioned and can be rolled back.

Yes - that was the example I was thinking of.
Thanks for finding it.

Yes, thank you very much. This is very helpful for me as it also shows how to disable the "touch" part of the screen!
