Problem:
How do I read all available samples in the CAN buffer using the CAN Read VI?

Solution:
You can use the Number of Samples Pending property to read all available samples in the CAN buffer. To access and use this property, follow the steps below:

1. Drop a CAN Get Property VI from the CAN channel API palette onto the block diagram.
2. Right-click on the VI, and click on the Number of samples pending entry from the Select type menu.
3. Wire the Number of Samples Pending output of the CAN Get Property VI into the Number of Samples to Read input of the CAN Read VI.

Each time the CAN Read VI executes, it returns all available samples in the CAN buffer.
