OPERATION The LCD application exercises a 16x2
character liquid crystal alphanumeric display. The display is connected in 4-bit mode to
save on I/O connections (6 in total). Command codes and ASCII data are sent 4
bits at a time, high bits first. The 4-bit data words are latched into the
display using control input E. RS selects command or data mode. The display requires an initialisation sequence
to set its operating modes, and commands to control the cursor position,
clear the display etc. A sequence of fixed characters is sent,
then an endless variable count in the last position. |
