Typical implementations
An embedded application where the LCD is written to by a separate microprocessor or computer would typically send
a Form Feed character followed by up to 80 characters, possibly interspersed with carriage returns to reduce the
number of characters to be transmitted.
It is unlikely that such as application would make use of the backspace function since there are unlikely to be errors
in data entry, although the line-wrap feature may be used to allow the microprocessor to treat the display as a con-
tiguous array of 80 characters with no requirement for carriage returns.
A terminal-like application, however, where the user is permitted to type any characters on the LCD (perhaps using
an application such as HyperTerminal) would almost certainly make use of all the features built into the module such
as line-wrap and special characters to make the interface more user friendly.
LCD adjustment
A potentiometer is provided on the module interface circuit board to allow the contrast of the LCD display to be ad-
justed.
