serdisplib started as a library to drive serial displays with built-in controllers

serdisplib started as a library to drive serial displays with built-in controllers.
beginning with version 1.95 support was added for parallel driven displays. anyhow: the name 'serdisplib' will not change. 

at the beginning it was only planned to add support for optrex 323 displays using some patches to graphlcd, but soon i decided to create a separate library which can be used independently.
an interface-module and some patches are now the glue between graphlcd and the library. 

the serial in "serial display" characterises the way of how the data is transferred to the display controller: data is sent bit by bit using a single input line. several (few) other lines are controlling things like timing (clock), data or command, ... 

parallel driven displays transfer data using a data-bus (eg. 4, 8, 16-bit wide data-bus) and some signal wires. 

version 1.97 introduces support for an USB driven display
