Using Nokia LCD

[HJota]

I hall

I know it's not very new, but I think is interesting.
This program receive text information true rs232, display in a Nokia 3310 LCD capital and small letters, display 3 sizes off characters, variable and fixes size of characters, normal and inverted screen and character.

I've test the program connecting the Tx of my Pc tru a 74ls04 and it works greatly with 3.3 v

Have a nice time!
