external peripheral connetion process ....please

Hi there 
I was working on a project so I brought mini2440 board and I want to drive
simple lcd(16x2)(alphanumeric lcd). Is it possible? If it is reference
progrm or something?

Sure it is possible. Obviously, you are not ale to use touchscreens that
are usually used with this product.

http://homepage.hispeed.ch/peterfleury/avr-software.html

and his HD44780 library.

Then using the FriendlyARM toolchain cross-compile his modified library to
run on the mini2440.

To do this you will need to enable GPIO in the kernel and access it via
userspace sysfs commands.

Certainly a good learning experience!

Have a look at the Dec 2015 issue of the Odroid magazine and the SHT15
sensor article for GPIO guidance.

Thanks let me check once
