ledmon

small program running on arduino atmega328p(the UNO) to visualize no ip/wrong ip/correct ip. on failure to get info from machine it will go through all colors until it gets info.

pre-setup

• connect red led to port 9 of your UNO, this will show 'no ip' status
• connect yellow led to port 10 of your UNO, this will show 'wrong ip' status
• connect green led to port 11 of your UNO, this will show 'correct ip' status
• install gcc-avr avr-libc binutils-avr gdb-avr avrdude

in theory it could all work with another arduino or similar board but you will have to do some porting here and there regarding the device preferences in the makefile and the ports defined in the main code.

setup

1. cd ledmon
2. make flash

ipcheck

small daemon to check if the internal ip assigned is correct, will send result of this info over serial to ledmon.

pre-setup

• install gcc make

setup

1. cd ipcheck
2. make build
3. ./ipcheck youriface wantedipaddress comport e.g.: ./ipcheck eth0 192.168.0.104 /dev/ttyACM0

usage

usage: ipcheck [iface] [wanted ip] [comport] (--no-daemon)

it's advised to just run this as daemon in the background but the --no-daemon flag can be helpful in debugging configuration.
