front panel will light up when the data is being logged. A
100 ms delay is placed here so that the user has enough
time to observe the LED status. This lets you know that
the VI data logging feature is working — this is especially
useful when running in the real time mode. The false case
simply turns these LEDs off.
Box #15-0 through -4:
This is a stacked sequence: a flat sequence that is
stacked one on top of the other mainly to conserve space.
There are five frames in this sequence (0 through 4) which
will execute in that order.
Most of the frames have a
delay placed in them to
accommodate the serial LCD that
they are controlling, which is a
NewHaven 2x16 display (NHD-
0216K3Z-FL-GBW-V3). The UART
control is transmitting or “writing”
serial data at 9600 baud in
hexadecimal format to the LCD.
To get hexadecimal control
characters out to the LCD, select the string constant and
from the pull-down menu change the display from normal
to hexadecimal; see box #15-0, 15-1, and 15-3.
Most of the NewHaven control codes begin with FE
(hex) and then certain other numbers to clear the LCD,
change lines, etc. There is text in each frame briefly
explaining what that frame is doing. Of course, these hex
codes will probably change depending on the particular
Good luck and enjoy developing new projects for
your MyRIO. Not all functions and capabilities of the
MyRIO have been demonstrated in this series of articles,
but hopefully enough has been presented to help you get
started using the MyRIO and working with LabVIEW. It is
a great system to develop with and has many other
Again, a great MyRIO resource is at www.ni.com;
search for MYRIO to see some of the things other people
have been doing with their units and LabVIEW. NV
