CONFIG_IO_FUNC

This structure defines the configuration for a single I/O function port, including its assigned port number and active signal level. It is primarily used in remote control or configurable I/O settings to map logical functions to specific digital I/O channels.

BYTE#	Field Name	Data Type	Value	Remarks
0	_iPort	char	-1 ~ 15	Digital port number assigned to this I/O function (-1: Not used, 0-15: Active port index)
1	_bLevel	char	0 or 1	Active signal level for the port (0: Low active, 1: High active)

Total size: 2 bytes

Defined in: DRFS.h

typedef struct _CONFIG_IO_FUNC
{
    /* Port number (-1: unused, 0–15: valid port index) */
    char _iPort;

    /* Signal level (0: low, 1: high) */
    char _bLevel;

} CONFIG_IO_FUNC, *LPCONFIG_IO_FUNC;

Note

• This structure is a fundamental component of higher-level I/O configurations such as CONFIG_REMOTE_CONTROL.

• Use _iPort = -1 to deactivate a function or leave it unassigned.

• The _bLevel field defines the trigger logic for detecting or outputting signals.
