Macro Definition Documentation

DISPLAY_CMD_RESERVED

#define DISPLAY_CMD_RESERVED   32

Common Display_control command code reservation offset. Display driver implementations should offset command codes with DISPLAY_CMD_RESERVED growing positively

Example implementation specific command codes:

#define DISPLAYXYZ_CMD_COMMAND0     DISPLAY_CMD_RESERVED + 0
#define DISPLAYXYZ_CMD_COMMAND1     DISPLAY_CMD_RESERVED + 1

DISPLAY_STATUS_RESERVED

#define DISPLAY_STATUS_RESERVED   -32

Common Display_control status code reservation offset. Display driver implementations should offset status codes with DISPLAY_STATUS_RESERVED growing negatively.

Example implementation specific status codes:

#define DISPLAYXYZ_STATUS_ERROR0    DISPLAY_STATUS_RESERVED - 0
#define DISPLAYXYZ_STATUS_ERROR1    DISPLAY_STATUS_RESERVED - 1
#define DISPLAYXYZ_STATUS_ERROR2    DISPLAY_STATUS_RESERVED - 2
