The next example program fetches custom character definitions from EEPROM and
sends them to the serial LCD using a subroutine named
to do before calling the subroutine is set the value of two variables:
charBase
(0, 1, 2...7). The
to look in EEPROM for the beginning of the character definition. For example, to
transfer the
the Parallax Serial LCD's character memory, use these three commands:
If your program has to choose among many different custom characters definitions, you
can replace
