Hardware timed non periodic analog output

[Jonathan_S1]

Overview
This example demonstrates how you can update an analog output using hardware timing using a non periodic digital waveform.

Description:
This can allow the user to maintain a high timing resolution while saving memory space for the analog output.  This was brought to my attention here. The example uses three tasks.

1. An analog output task.  This task outputs voltages from an array.  The values need to be updated at specific times but in a non-periodic manner.
2. A digital output task.  This task contains a waveform that tells the analog output task to update.  This allows you to create a random update pattern.
3. A counter task.  M-series cards cannot do hardware timed DIO using an internal timebase, so we can use a counter to provide an "external" timebase.

You will need to physically connect the digital output line to the analog output trigger line.

Steps to Implement or Execute Code:

1. Open the block diagram.
2. Configure the channel for each task.
3. Run the VI
