BYTE Read_Ext_IO (WORD nDevNo)
nDevNo = Device Number
return value: State of I/O pin
This function allows the state of the I/O pin to be read. This enables
the pin to be used as input.
If the voltage connected to the I/O pin is in the range of „logic 0“, then
the function returns a value of 0. If the voltage is in the range of
„logic 1“, then the function returns a value of 1. For the appropriate
voltage ranges, please refer to the specificati ns in section 1.2.
Caution:
In order to use the I/O pin as input, the transistor must be disabled
(
HI-Z
).

Almost all functions of the eGrabber-4plus can be controlled by
routines of the driver. We recommend explicitly the utilization of the
standard functions.
