quanser.hardware.hil.get_integer_property
Get the values of the given integer properties of the board.
[values, err] = board.get_integer_property(properties)
Returns the values of the given integer properties of the board. Not all boards support properties. Properties are generally used for features of the board that may be reconfigured periodically, rather than configured once through the card-specific options (see set_card_specific_options). They are also used to get information about the card. For example, properties may often be used to get the vendor ID and product ID of a card, or the manufacturer. They might also be used for calibrating the A/Ds or D/As on the card.
Properties are identified by a numeric code and boards may have property codes unique to the board. Such custom properties are always assigned a property code of 128 or higher. Property codes between 0 and 127 are reserved for standard properties. There is a separate set of property codes for integer properties. Double-valued properties have their own set of property codes, as do string properties.
If no err output is provided then it throws an exception if an error occurs. In generated code it prints the error message. Use hil_get_error_message to get the message associated with an error code.
