SDRplay Community Forum

Hi all Reading through the forums I see that there seems to be some interest in dedicated spectrum analyser software for the RSP series of SDR radios. I have been working on such an application for the past few months and it is now starting to get a stage stage where I hope to be able to release a b...

Hi Steve At the end of the API document there is a section marked API Usage. There is some simple code written in C/C++ that illustrates how mir_sdr_StreamInit and mir_sdr_StreamCallback are set up and used. It's written for Windows but should need little changing apart from the semaphores to get it...

Hi Steve, and Tech Support The first version of the code I posted set decimation before starting the stream, and that seems to be the version Support is referring to.The API documentation for mir_sdr_DecimateControl states: "Note: Requires internal stream thread to have been created via mir_sdr_Stre...

Hi Steve I'm afraid I can't help you there. Maybe someone from tech support could explain the reasons. I did see an early version of the source code for EXTIO.dll on GitHub some time ago - https://github.com/SDRplay/ExtIO_SDRplay. I don't know if it's still there though, as it used mir_sdr_Init (now...

Hi Steve You should be able to achieve an effective sampling rate of 192KHz by using a sampling rate of 3.072MHZ and a decimation factor of 16. I've attached an example (StreamingSample_2.zip) with source code, that allows you to play around with various sampling rates and decimation factors. It's b...

Hi Nick I have the same sort of problem. I thought I understood what was supposed to happen, but now having re-visited the API documentation, I'm not so sure. I'm sure there are other coders out there with the same problem. I've been involved in other parts of my project for some time and have not g...

Hi Here is some sample code that shows how to use the API streaming function with callbacks, written in C#. It was written using Visual Studio 2017, running under Windows 10, 64 bit. The sample project has been configured to compile to 32 bit mode. After unzipping the code to a folder, you will need...

Hi N2NIC That code has a bug in it. It wont run when used in 32-bit mode. Andy in tech support finally traced the problem for - an absolute hero ! In the meantime, I'll redo a simple demo and post the source code here for you. Playground link is: http://www.sdrplay.com/playground/ but it does requir...

Hi Bill

The API will have mir_sdr.h, I don't know about mirsdrapi_rsp.h as I've only downloaded the Windows API.

If you are thinking of adding functionality to the RX keypad, then how about allowing the buttons to be customised ? Currently the buttons allow for selection of preset amateur radio bands, using sampling rate and decimation factors to obtain the required coverage for each band. Many users, myself i...
