Data Structures | |
struct | ARING_TypeDef |
Defines segment COM and BIT fields for A-wheel (suited for Anim) More... | |
struct | BATTERY_TypeDef |
Defines segment COM and BIT fields for Battery (suited for Anim) More... | |
struct | Block_TypeDef |
Defines segment COM and BIT fields for top and bottom row blocks. The bit pattern shown above for characters can be split into upper and lower portions for animation purposes. There are separate COM and BIT numbers which together represent a set of stacked blocks which can be shown on two rows in the segmented LCD screen. More... | |
struct | CHAR_TypeDef |
Defines each text symbol's segment in terms of COM and BIT numbers, in a way that we can enumerate each bit for each text segment in the following bit pattern: More... | |
struct | EM_TypeDef |
Defines segment COM and BIT fields for Energy Modes on display. More... | |
struct | MCU_DISPLAY |
Defines prototype for all segments in display. More... | |
struct | NUMBER_TypeDef |
Defines segment COM and BIT fields numeric display. More... | |
