Enumeration Type Documentation

enum Alignment_enum

Horizontal text alignment on the line.

Enumerator:
LEFT 

Left-oriented, naturally gravitate closer to the left edge of the screen.

CENTER 

Center-oriented, try to fit in the middle of the available space with equal free space to the left and right of the text.

RIGHT 

Right-oriented, naturally gravitate closer to the right edge of the screen, leaving any remaining free space to the left of the text.

Definition at line 623 of file lcd_base.h.

enum BacklightPwmCtrl_enum
Enumerator:
Constant 

When the pin is a simple on/off switch.

Direct 

Control the brightness with PWM, as the control pin is sourcing the current to drive the backlight LEDs.

Indirect 

Control the brightness with PWM, as the control pin is sinking the current which drives the backlight LEDs.

Definition at line 683 of file lcd_base.h.

enum ColorDepth_enum

Color depth.

Enumerator:
RGB16 

16-bit colors, pixels can have 65K+ distinct color values

RGB18 

18-bit colors, pixels can have 262K+ distinct color values

RGB24 

24-bit colors, full 8 bits per component, 16M+ distinct color values

Definition at line 609 of file lcd_base.h.

enum Orientation_enum
Enumerator:
LANDSCAPE_REV 

Top row of the screen is at 12 o'clock.

Top row of the screen is at 9 o'clock. Top row of the screen is at 6 o'clock.
