Digital I/O
The DAQPad-MIO-16XE-50 contains eight lines of DIO for
general-purpose use. You can individually configure each line through
software for either input or output.
The hardware up/down control for general-purpose counters 0 and 1 are
connected onboard to DIO6 and DIO7, respectively. Thus, you can use
DIO6 and DIO7 to control the general-purpose counters. The up/down
control signals are input only and do not affect the operation of the
DIO lines.
Programmable Function Inputs
The DAQ-STC provides a very flexible interface for connecting timing
signals to external circuitry. The DAQPad-MIO-16XE-50 uses the
Programmable Function Input (PFI) signals on the DAQPad-TB-52 for
connecting to external circuitry. These connections are designed to enable
the DAQPad-MIO-16XE-50 to both control and be controlled by other
circuits.
There are a total of 13 timing signals internal to the DAQ-STC that can
be controlled by an external source. These timing signals can also be
controlled by signals generated internally to the DAQ-STC, and these
selections are fully software configurable. For example, the signal routing
multiplexer for controlling the CONVERT* signal is shown in Figure 2-3.
