How to generate not nillable complexType with ant task autotype

Question

Hi all,
The file types.xml created by ant task autotype contains, among others, all element definitions of my java classes.
For testing purposes I have a simple class that holds (wraps) only a string. In the types.xml it is shown as followed:
<xsd:complexType name="StringHolder">
<xsd:sequence>
<xsd:element name="mystring"
type="xsd:string"
nillable="true"
minOccurs="1"
maxOccurs="1">
</xsd:element>
</xsd:sequence>
</xsd:complexType>
Somehow nullabel is always true, but I want to be false. Does anyone knows how?

Hello digitxm,
Since the hardware you have is the limiting factor, with the NI 6008 you can perform a software timed pwm output if timing in your application is not critical (your cycle time is in the seconds range and you do not mind some milliseconds of delay) you can use a digital output with software timing control for your PWM generation. Also, see how to use AO channel(s) to control the voltage level of a square wave output (period of the square wave can be varied). Otherwise, this can be accomplished by using the following example on generating a digital waveform using non-regeneration in order to update frequency and duty cycle on-the-fly using National Instruments M Series or X series DAQ devices.
