Not sure how it works but it would be awesome if it was just a serial connection.
Any input or ideas would be helpful, thanks.

On the K5, the serial port is inside and uses a somewhat uncommon connector (with difficult to attach wires without a special $300USD tool) and the cover is glued on, and the serial I/O is 1.8v TTL (which may need voltage level conversion to talk to a microcontroller)
, and you may need to cut a notch in the back cover through which to feed a serial cable (unless you leave the back cover partially detached), and then you would have a semi-permanent cable always dangling from it. And feeding "keypresses" to a K5 is complicated by the fact that it only has ONE key (the home key) so you would need to simulate a touchscreen keypad. Not pretty.
It would be much easier to talk to your kindle through USB or wifi.
There is now a free USB Host stack in software for microprocessors so it could talk to the kindle. Or use the kindle OTG as a USB host so the microprocessor can use smaller simpler USB device mode. Once you have that all figured out, you still need to know how to feed keypresses to the K5. This procedure is documented for a DX and K3, but I have not seen how to do it on a K5 yet.
If somebody knows how to force (native mode) keypresses on a K5, please post that info (or a link to it) here. Thanks.
