OmniPreSense Corporation 

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.
