# Lora SA(Spectrum Analyzer)
|
||||
RF Spectrum Analyzer using Lora Radio
|
||||
|
||||
RadioLib SX126x Spectrum Scan
|
||||
|
||||
Perform a spectrum power scan using SX126x.
|
||||
The output is in the form of scan lines, each line has 33 power bins.
|
||||
First power bin corresponds to -11 dBm, the second to -15 dBm and so on.
|
||||
Higher number of samples in a bin corresponds to more power received
|
||||
at that level.
|
||||
|
||||
The spectrum analyzer perform power measurements in the configured bandwidth.
|
||||
|
||||
To show the results in a plot, run the Python script

||||

This directory is intended for project header files.
|
||||
|
||||
A header file is a file containing C declarations and macro definitions
|
||||
to be shared between several project source files. You request the use of a
|
||||
header file in your project source file (C, C++, etc) located in `src` folder
|
||||
by including it, with the C preprocessing directive `#include'.
|
||||
|
||||
```src/main.c
|
||||
|
||||
#include "header.h"
|
||||
|
||||
int main (void)
|
||||
{
|
||||
...
|
||||
}
|
||||
```
|
||||
|
||||
Including a header file produces the same results as copying the header file
|
||||
into each source file that needs it. Such copying would be time-consuming
|
||||
and error-prone. With a header file, the related declarations appear
|
||||
in only one place. If they need to be changed, they can be changed in one
|
||||
place, and programs that include the header file will automatically use the
|
||||
new version when next recompiled. The header file eliminates the labor of
|
||||
finding and changing all the copies as well as the risk that a failure to
|
||||
find one copy will result in inconsistencies within a program.
|
||||
|
||||
In C, the usual convention is to give header files names that end with `.h'.
|
||||
It is most portable to use only letters, digits, dashes, and underscores in
|
||||
header file names, and at most one dot.
|
||||
|
||||

This directory is intended for project specific (private) libraries.
|

PlatformIO will compile them to static libraries and link into executable file.
|

|

The source code of each library should be placed in an own separate directory
|
||||
("lib/your_library_name/[here are source files]").
|
||||
|

For example, see a structure of the following two libraries `Foo` and `Bar`:
|

RadioLib SX126x Spectrum Scan
|
||||
|
||||
This example shows how to perform a spectrum power scan using SX126x.
|
||||
The output is in the form of scan lines, each line has 33 power bins.
|
||||
First power bin corresponds to -11 dBm, the second to -15 dBm and so on.
|
||||
Higher number of samples in a bin corresponds to more power received
|
||||
at that level.
|
||||
|
||||
To show the results in a plot, run the Python script
|
||||
RadioLib/extras/SX126x_Spectrum_Scan/SpectrumScan.py
|
||||
|
||||
WARNING: This functionality is experimental and requires a binary patch
|
||||
to be uploaded to the SX126x device. There may be some undocumented
|
||||
side effects!
|
||||

||||

This directory is intended for PlatformIO Test Runner and project tests.
|
||||
|
||||
Unit Testing is a software testing method by which individual units of
|
||||
source code, sets of one or more MCU program modules together with associated
|
||||
control data, usage procedures, and operating procedures, are tested to
|
||||
determine whether they are fit for use. Unit testing finds problems early
|
||||
in the development cycle.
