GPIO_PORT

This structure defines a single GPIO (General-Purpose Input/Output) port entry, representing both the port’s index and its corresponding data value. It is primarily used as an element within burst operations such as WRITE_SERIAL_BURST or GPIO_SETOUTPUT_BURST.

BYTE#	Field Name	Data Type	Value	Remarks
0	`_iIndex`	`unsigned char`	0 ~ N	Index number of the GPIO port Specifies which port this entry refers to
1	`_fValue`	`float`	0.0 or 1.0	Current port value or output state 0.0: Low (OFF) 1.0: High (ON)

Total size: 5 bytes

Defined in: DRFS.h

typedef struct _GPIO_PORT
{
    /* Port index (0~N) */
    unsigned char _iIndex;

    /* Port value (0.0: low, 1.0: high) */
    float _fValue;

} GPIO_PORT, *LPGPIO_PORT;

Note

This structure acts as the basic data unit for GPIO operations in burst or single mode.
_iIndex determines which GPIO channel is targeted, and _fValue specifies the desired output level.
Used in both digital output control and burst transmission structures.
