This is some code for my old protoboard version .1 i think. Im just posting it here for reference it has some good things like.
Real time clock
RX serial recieve interupt
Menu system via rx
password recogitition
pretty much all it did was keep time and beep, it was all the fluff that was hard. The whole project is attached as a HomeControl.zip
here is the main .c file

Just for reference this is what i use to connect to nfs drives on my server
via script, GalacticAC is defined in /etc/hosts with the ip of my server
#! /bin/bash # script to mount my files on webserver sudo mount -t nfs GalacticAC:/mnt/sdb1/ /home/michael/server/sdb1
and via fstab (will mount automatically on boot)
GalacticAC:/mnt/sdb1/ /home/michael/server/sdb1 nfs defaults 0 0
