USB-LIN: Put Master in sleep mode and remotely wakeup

[mr-vizsla]

Introduction

This VI shows that you can manually place a USB-LIN device in sleep and active mode.  This example also shows how you can use another LIN device to wake up a sleeping LIN device. 

In order to manually place a USB-LIN device in sleep mode, you have to call the ncSetAttr.vi and indicate that the device should be in an active or sleep mode.  I have implemented this in a custom VI, USB-LIN Sleep Control_LV86.vi.  This subVI is used in the following images to implement this functionality.

Here is a quick example of waking a LIN device from sleep mode.  We are using the USB-LIN Sleep Control_LV86.vi to place the Master device in a sleep mode.  Then we will be using a second USB-LIN device to wake the Master LIN device.  Here is the necessary setup:

- two USB-8476s

- first USB-8476 runs LIN Master Send Header Frame Respond and  Receive_LV86.vi

- second0 USB-8476 runs LIN Master Send Header Frame and  Receive_LV86.vi

Perform the following operations:

Step 1: Choose the interface.

Step 2: Press the VI's run button.

Step 3: Choose the other interface.

Step 4: Press the other VI's run button.

Step 5: Press the Update LIN Response Entry Frame? button.

Step 6: Press the Write Header Frame button and noticed the  results in the table.

Step 7: Press the Write Header Frame button and noticed the  results in the table.

Step 8: Press the Sleep? button and noticed that the  Is asleep? indicator shows you that the LIN device is  asleep.

Step 9: Press the Write Header Frame button and noticed the  LIN BUS Error, which indicates the Master received the message as a wake-up but  did not interpret the message. Also notice that the Is asleep? indicator is no longer lit as the Master is awake.

Step 10: Press the Write Header Frame button and noticed the  results in the table.
