16-bit digital inputs on the ACL-8112. The bit 0 to bit 7 are defined as
low byte and the bit 8 to bit 15 are defined as the high byte .
Syntax
int _8112_DI( int port_number, unsigned char *data )
int _8112pg_DI( int port_number, unsigned char *data )
Argument:
port_number:
To indicate which port is read,
DI_LO_BYTE
or DI_HI_BYTE.
DI_LO_BYTE: bit 0 ~ bit 7,
DI_HI_BYTE: bit8 ~ bit15
data:
return value from digital port.
Return Code:
ERR_NoError
ERR_BoardNoInit
ERR_PortError
