Support for HD44780&FTDI

[GoogleCodeExporter]

I'm trying to use a 20x4 HD44780 display with my rt-n56u. The connection is 
made through a FTDI chip FT245RL.

The only package available it's lcd4linux but i didn't managed to make it work 
even on a PC. LCD4Linux doesn't know how to use libftdi (or i don't know how to 
set it right).

I've managed to make the LCD show some infos on the PC, with lubuntu and 
LCDproc.

Is there any tutorial for building LCDproc for rt-n56u? Or is there any 
compatible architecture on openwrt.org?

Thanks!

You'll need to compile the firmware with FTDI driver I suppose. You'll also 
need some daemon which will send data via serial connection in loop.
I haven't seen such tutorials in the internet =)

I think it is much easier to connect display to to some board like Arduino. The 
router should see Arduino as /dev/ttyACM0. Then you'll be able to send data 
easy way: echo "some data" > /dev/ttyACM0. Arduino should do the work of lcd 
controller, and you should see 'some data' on lcd.
