a multi-function display for isolde - part 8

A lot of Arduino toys keep arriving in the Asia to USA transit pipeline. Because of the 20 to 25 shipping time I have been trained to put stuffs that I anticipate I can use way ahead of time. I also tend to buy 2 if I anticipate the item would be good because I need to keep one copy of the system for continue code development and maintenance. I however buy 1 if the item is unknown or expensive. Most of these stuff cost between $1.50 to $6 so it is not like I am going poor house doing shopping spree.

The rude awakening that my code exceeded the 2k bytes of RAM in the Atmel ATmega328 uC's quickly put the brake on the progress. I have spent some time in the weekend investigating what are the big RAM consumers and to find way to work around them. Else I have to readjust the list of features that I set.
