Driver Configuration
The LCD Direct Driver is configured through the setting of macro definitions. These macros are illustrated
in the sample code. The following table briefly describes the location of each of these macros and their
location in LCD Direct Drive demonstration code. For examples of each macro usage, refer to the
demonstration code.
