AVR-Chat

Hi,

    I have to interface a 5 volts 160x160 LCD display to a 3.3 volts system 
and after reading the LCD specs I am quite sure that I will not violate the 
minimum voltage levels of the inputs but I may have to use partially the LCD 
memory for other functions so I may have to use it bi-directionaly. My CPU 
will be a AtMega324P. Will series resistors to limit current in the data bus 
be enough in this case ? I have not found any specs in the data sheets about 
how much current the internal protection diodes on the AVR's would take :-(

Best regards,
Alexandre Guimaraes
