Re: hacking linux - framebuffer console/i2c keyboard

Hi,

in message [ref] you wrote:

How would one hack up a i2c keypad interface to appear as a keyboard on a
system, and get messages to stdout appear on an LCD? Specifically, I'm
working on 823e. I have no idea where or how to start. I know each thing
works correctly, that is, I have the i2c keypad and the LCD properly working
on the system. I'm just at a loss on how to tie it all together.

Check out the LWMON configuration in our kernel sources; see
http://www.denx.de/re/linux.html

The arch/ppc/8xx_io/lwmon_kbd.c  file  implements  a  (very  special)
keyboard  driver  that  is attached over I2C (using the I2C driver in
drivers/i2c/i2c-simple.*).

Hope this helps,

Wolfgang Denk
