BOOL initial_SIO(BYTE Isolate_Type, BYTE DIO_NPN)
Initial machine for IO and watch dogtimer.
•
Isolate_Type: DIO type.
1: Isolated DIO; 0: Non-Isolated DIO(GPIO).
•
DIO_NPN: DI / DO type.
1: PNP (Source) mode for European rule;
0: NPN (Sink) mode for Japanese rule.
Return:
TRUE (1): Success.
FALSE (0): Fail (Driver not exists, or version is too old, or machine not match).
BOOL get_IO1_configuration(BYTE *Iso, BYTE *DI_mode, BYTE *DO_
mode, WORD *Mask)
BOOL get_IO2_configuration(BYTE *Iso, BYTE *DI_mode, BYTE *DO_
mode, WORD *Mask)
Get DIO configuration (by variable)
•
Isolate_Type: DIO type.
1: Isolated DIO; 0: Non-Isolated DIO(GPIO).
•
DI_mode ([7:0]): DI type, pin setting by hexadecimal bitmask only for
Isolated DIO.
0xFF: PNP (Source) mode for European rule; 0: NPN (Sink) mode for
Japanese rule.
•
DO_mode: DO type only for Isolated DIO.
1: PNP (Source) mode for European rule; 0: NPN (Sink) mode for
Japanese rule.
•
Mask ([15:0]): In / Out, pin setting by hexadecimal bitmask only for
Non-Isolated DIO(GPIO).
1: Output; 0: Input
Return:
TRUE (1): Success.
