SDR# ComPortFrequency plugin

SDR# plugin to send current frequency value to the selected COM port with 9600 baudrate.

Installation: Add line to Plugins.xml file into <sharpPlugins> section:
<add key="ComPortFrequency" value="SDRSharp.ComPortFrequency.ComPortFrequencyPlugin, SDRSharp.ComPortFrequency" />

Plugin for old SDR# versions is also available to download under "Files" section.
https://sourceforge.net/projects/sdrsharp-comportfrequency/files/SDRSharp.ComPortFrequency_for_net_3.5.dll/download

May be used to control input RF filters using Arduino, for example:

void setup()
{
Serial.begin( 9600 );
}

void loop()
{
while (Serial.available())
{
String freq = Serial.readString();
// "freq" should contain something like 434175000
}
}

One more arduino example could be found under "Files" section. This sketch is designed to control Janilab's HF multi band-pass filter.
