I am working on some older marine equipment that use either the Hitachi HD44780 or a NEC UPD16434 LCD driver. I believe that the drivers are bad as the two units work with the exception of a "fluttering" partial display. I get the outline of the 5x7 blocks, but nothing else and these flutter.
My question is: can I simply replace these drivers or do they contain programing that is specific to the LCD / equipment.
If they contain programing, can then be copied and then replaced?
Thanks!!
