char num_cols; // Columns on the display
char num_rows; // Rows on the display
// Start address of each row (up to 4 rows)
char row_addresses[4];
// Minimum voltage for contrast control
float anaout_contrast_min;
// Maximum voltage for contrast control
float anaout_contrast_max;
// Minimum duty cycle for contrast control
int pwm_contrast_min;
// Maximum duty cycle for contrast control
int pwm_contrast_max;
// Default scaled value for contrast control (0-255)
char def_contrast;
} Flex_LCDConf;
