Used With All devices except Personal Daq/54
Description
daqIORead allows you to read the specified port on the selected device. The read operation will return the current state of the port in the
value parameter. Normally, if the selected port is a byte-wide port, the port state will occupy the low-order byte of the value parameter.
Digital IO channels for the port correspond to each bit within this low-order byte. If the bit is set, it indicates the channel is in a high state. If
the bit is not set, the channel is indicated to be in a low state.
