e-ink kindle custom app

[wildcolor]

Dear all

I am wondering if the e-ink kindles can do something like below?

I want to be able to control the kindle using an extenal keyboard, say if I press button 'T', the kindle will draw a Triangle, press button 'C', the kindle draws a Circle.

Note, I want to use an external (say computer) keyboard to control it.


I am having a K4NT by the way.

USB host mode would be needed to connect a conventional USB keyboard. The chipset is capable of running in USB host mode but it needs kernel support that is not there out of the box. Search for USB host mode in this board to get more info. It has been done, but is poorly documented.

As for the painting circles and triangles part, that would be easier (depending on your programming knowledge of course). Just showing certain images for certain buttons could be realized quickly e.g. in shell scripting.

You could also connect the keyboard to Raspberry Pi then use SSH/Wi-Fi to forward the command to Kindle and make the Kindle display an image with circle or triangle.

Yeah that'd work easily

you could use a bluetooth keyboard, and use an android device as a middle man to receive the bluetooth input and then send commands to the kindle via wifi (via ssh, as dsmid said above)

thanks for all the reply.

I need the program to display certain images based on the button press from the keyboard. The 'circle' and 'triangle' were just examples. What I need will be more complicated and can vary very much. So I can't just use simple images.

I want the kindle program to generate the stimulus (i.e., circles/triangle) and also to read in the keyboard 'button presses'.

is this something doable on the kindle? or any other e-ink devices?

Everyone here is having trouble with their Crystal Ball application, none of us can read your mind.

Tell us what your overall objective is, we may be able to give you more specific (to your objective) advice.

Asking for a solution to a small example case is not going to get you anything other than solutions to the small example case.

And if what you have in mind is a closed source application you are developing, do not be surprised if you do not get any support from the members of this forum.
