ok thanks, sorted that out, now since i didn't know how to send it any data i used the example code from the sparkfun site, i uploaded the code to my 328P which is what's suggested for this code, then when i turned it on the display just seems to flash randomly, it doesn't display anything that actually makes sense lol.
This is the display i'm using
http://www.sparkfun.com/commerce/product_info.php?products_id=9767the datasheet says that i can send it data in one of 2 ways, either using TTL or SPL serial communication, i'm currently trying to use TTL for just the one wire going to RX but i think the example code is trying to communicate with it via SPL but i'm not real sure if this is the problem and if it is, how to change it.
if anyone knows what the problem could be, I appreciate any help.
