7.3 _8112_DI
Description
This function is used to read data from digital input port. There are
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
Example:
See Demo program . Demo Program 'DI_DEMO.C'
7.4 _8112_DI _Channel
Description
This function is used to read data from digital input channels (bit).
There are 16 digital input channels on the ACL-8112. When performs
this function, the digital input port is read and the value of the
corresponding channel is returned.
* channel means each bit of digital input ports.
Syntax
int _8112_DI_Channel(int di_ch_no, unsigned int *data )
int _8112pg_DI(int di_ch_no, unsigned int *data )
