Data Output
–
set to control the data which is output.
Command
Name
R/W
Value
OF
FFT Output On
Write
Results from the FFT processing of each buffer
will be sent. Each buffer is 1024 samples.
Data is output with json output format.
Of
FFT Output Off
Write
Turns off FFT output.
OJ
json Mode On
Write
‘
Turns on output to format data in json
format. An example would output:
{"speed":0.58, "direction":"inbound",
“time”:105, :tick”:135
}
Oj
json Mode Off
Write
Turns off json output mode.
OR
Raw ADC Output On
Write
I and Q output buffers from the ADC will be
sent. Data will alternate between outputting
the I buffer and then Q buffer.
Or
Raw ADC Output Off
Write
Turns off output of the I and Q buffers.
OL
LED Control
Write
Turn the LEDs on (OL) or off (Ol). Turning off
the LED’s can save approximately 10mA of
current consumption.
O
n
Number Reports
Write
Define how many reports to provide.
n
is a
number between 1 and 9. The number
n
holds for time, magnitude, and speed.
OM
Magnitude Report
Write
Turn on reporting of the magnitude associated
with the speed. The magnitude is a measure
of the size, distance, and reflectivity of the
object detected. Type Om to turn magnitude
off. When turned on, magnitude information
comes before speed information.
OS
Speed Report
Write
Turn speed reporting on or off. Default
operation speed is reported. Use Os to turn it
off and OS to turn it back on.
OT
Time Report
Write
Turn the time report on. Time is reported as
the seconds and milliseconds since the last
reboot or power on. For example, 137.429,
3.6 is read as 137 seconds and 429
milliseconds with a speed of 3.6 m/s. If
magnitude is turned on, the data is provided
as time, magnitude, speed.
