Get keystrokes over putty

miomaz · 10-28-2014, 09:44 AM

hi,

I've been fooling around on my kindle (k4nt), (got USBnetwork to work, tried to setup vncviewer by hawhill, used kranu's webserver), in an attempt to play NEOscavenger on my kindle. Is there a way to have the kindle send keystrokes to the pc, possibly over putty?
I could then have kranus webserver running and program a small autoit3 script that translates the kindle output into windows keystrokes and mouse movements. I picture the kindle sending the pressed keys, it popping up as some identfying string in the putty console. Then I could copy the console's contents to the clipboard and parse for the identifying

Neoscavenger is a pretty baddass survival game check it out: Neoscavenger

thanks in advance.

Please use the forums correctly. This clearly belongs in the Kindle Developers' forum, to where I'm moving it.

Thanks.

I can't see that it would be a pleasurable exercise at all.
The graphics will be awful (low-contrast in the game means almost no contrast whatsoever on the Kindle).
The input - well, the number of keys is limited. Controlling a mouse cursor with that - ugh.

That said, it shouldn't be all that hard to script the needed parts in kindlevncviewer - but of course, you would need to learn a bit of Lua scripting. It's well possible that forwarding keypresses does work already.

Then again, from a K4 OSK - maybe not.

This game is perfect for it, because it's more or less a board game lacking animations. the main map looks alittle like die Siedler von Catan with its Hexagonal tiles. Plus I use something called NegativeScreen to adjust the colors and of course inverse the brightness of the monitor. The game is partially played with a mouse, but I can automate the mouseclicks with autoit, and also draw on the screen to see what I select in the game.
Anyhow, could you point me to some website/tutorial that might help me code this lua? In pseudo code i think all that needs scripting is:

If (button x pressed) {
//send message to putty
}

could you translate that into viable code? or is it more complicated than that?

I mentioned Lua because kindlevncviewer is scripted in Lua. But it is only prepared to send keystrokes (and, by the way, mouse pointer actions, i.e. absolute "movements") to the VNC server. So - not via PuTTY/SSH, but via VNC.

Just to get things straight: You want to forward the screen, too? And you want to use the "webserver" based way, i.e. emonitor? Or VNC? Via eMonitor, I guess your options are restricted to what the web browser actually can offer via event interfaces (I have no idea if it would work at all). Via VNC, and the vncviewer on the Kindle, you just have to push the proper events to the VNC server. You would probably have to extend https://github.com/hwhw/kindlevncvie...ter/config.lua to handle all the keys that the K4 offers (all keys handled now are K3/KDX centric). When you look at the file, you see the logic that sends a key event to the server - using the XK_Keyname constants - when a keypress is seen on the Kindle (the KEY_... events). K4 keys would probably have to be added. I'd add a line at the bottom, after all the

Code:

elseif code == KEY...

lines, that looks like this:

Code:

else print("unknown key event, code", code)

and then see what it outputs on console when you press the K4 keys. When you have the event codes, you can add your own lines, sending keystrokes to the VNC server.

I figured it would only work through your vncviewer when you mentioned the lua scripts. So yes, this project is intended for the vncviewer (plus the emonitor runs over the webbrowser ans consequently has that ugly bar that eats up 50 pixels or so). You have my thanks, I will see if I can get this to work and keep you guys updated.
