appear if the MyRIO is not running or if the iPad changes
network connections for some reason.
Now as you run your VI, you should see your
dashboard LED light up whenever: BUTTON0 on the
MyRIO is pressed; the pushbutton on the front panel is
clicked on; or when the switch from your dashboard is
MyRIO unit will be blinking if things are working correctly.
To stop your dashboard, touch the “STOP SIGN” icon in
the upper right corner.
Hopefully, you were able to get everything to work
together. Running the MyRIO with a real time VI and
using Wi-Fi published variables makes it so you can run
and control your MyRIO wirelessly from your iPad without
a host PC present. The Data Dashboard is also available
for Android devices, however, I have only used an iPad
and am not aware of any differences between the two
platforms (there are sure to be a few).
If you spend some time exploring your Data
Dashboard tutorials, you can learn how to change the
background colors, etc., to make your dashboard look
more interesting than the very simple one demonstrated
here. Once successful Wi-Fi connections exist between
the MyRIO and the iPad, time can be spent improving the
look of the dashboard. Figure 38 shows the Data
Dashboard for the final temperature control system that
will be covered in the final article in this series.
Next time, I will demonstrate how to translate the low
voltage/low current digital I/O signals from the MyRIO
ports into higher voltage and higher current real world AC
and DC loads. NV
