Script simulating PW3 keypress, PDF slideshow

[d0ugparker]

This link is a thread on simulating keypresses:

https://www.mobileread.com/forums/sho...d.php?t=118480

and calls out an old line of code that reportedly simulates a keypress:

echo "send 104" > /proc/keypad

"old," because it corresponds to an older model than the PW3--on the PW3 there doesn't appear to be a /proc/keypad device directory. I think I'm saying that correctly.

The same thread lists a web page URL for device names and keycodes from two .ini files from their related projects:

http://info.iet.unipi.it/~luigi/kindle

First, I have to figure out what to send.

I have run some tests on the PW3 to check for scancode values being generated through

/dev/input/event0

on a multi-page PDF using evtest, but its output wasn't providing any clues to 1) what codes needed to be sent to forward paging through a displayed PDF file, 2) what codes were needed for backward paging, nor 3) to what device or character stream they needed to be directed.

Ultimately, I'd like to get enough of the puzzle pieces to create a UNIX script, programmed to run self-contained on the Kindle, making a displayed PDF document go forward x pages, then backward x pages, then repeating until I hit the home button.

I will have an SSH connection to set things up, get it running, then disconnect and let it run.

Can anyone help provide the pieces I need? Thanks.

Thanks for the link. I was able to get most of the pieces in place. The basics are working 100% for an even this Saturday.

I used a hex editor to skinny down the Right and Left command text files making them as short as possible.

One thing I did differently that's worth passing on comes from this posting on the thread noted above:

Record the touch by:

2. performing the touch on the device (keep it short)
3. ctrl+c

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

(Source)

Not me. I played the script back on the PW3 using more instead of echo:

more touch.txt > /dev/input/event1

My loop repeats forward to the end, then backwards back to the beginning, then repeats.

Tips for those who follow:

1. Turn the screen saver off from the Helper menu first.
2. Turn on USBNet--I occasionally have to turn it off, then back on to connect.
3. Connect using your favorite method. I used PuTTY.exe.
4. Run the triggering script in the background--using an ampersand.
5. Stress test your implementation.

I'd like to have a more elegant way to activate and deactivate the script from the Helper menu, or in a menu of my own. My script loops permanently until I power it down to shut it off--programmer I'm not... yet. I'm on the Wiki https://wiki.mobileread.com/wiki/KUAL_What%27s_New looking for how to customize KUAL for my purposes.

Another helpful change will be figuring out how to merge the thread that discusses disabling the screen's touch interface--the untouchable kindle:

Thanks to everyone that contributed.

You will want to kill the process then, using `pkill -f scriptname.sh`

It shouldn't be hard to make a few KUAL buttons to start and stop the script.
