I have a BUNCH of 16 character messages (25+) that are to be displayed on an LCD. A master sends a command to a receiver (via RF) to light certain LED's, beep a piezo, and display various messages on the two lines of the LCD.

My idea was to have the master send just a code indicating what message each line should display in the receiver, and have the receiver unit read the associated messages from the EEPROM and display it. Since that would involve having another part in each receiver (possibly 40 or more of them), I have since decided that the master will transmit the two lines of the message, so I will only have to use an external EEPROM in the master.

Hopefully, my rambling explains the situation sufficiently...
