5.8 W_8454_DI
@ Description
To read the data of the digital input port. It is possible to read the 8
LSBs, 8 MSBs, or read only one bit channel by the DI relative
functions.
@ Syntax
Microsoft C/C++ (Windows, Win95 & Win-NT)
int W_8454_DI( UINT *DI_Value )
int W_8454_DI_L( UINT *DI_LValue )
int W_8454_DI_H( UINT *DI_HValue )
int W_8454_DI_bit( int Bit_No )
Visual Basic
Windows 3.11 Version:
