Hello to all, this is my first message to this group. I uploaded program written in C# for LimeSDR control (receive and transmit). Project can be downloaded from address:
Executable is at: https://github.com/GoranRadivojevic/LimeSDR-/tree/master/bin/Release
Short description: https://github.com/GoranRadivojevic/LimeSDR-/blob/master/README.md
(sorry but no help file for now).
LimeSDR# is based on PowerSDR and GSDR, written and tested on Win7 x64 using VS 2010 version. Because I don’t own LimeSDR board (v1.4) I had very limited time for experimenting (only two weeks) and before it is returned it will be great satisfaction for me if someone can verify that program also work on another PC. So far I tested VHF from 6m to 23cm receive and transmit, HF only receive (without board modification reception is poor). J12 GPIO pins are used for BPF control (0…3), TX out (4) and keyer DASH, DOT input (6,7). Usable sample rates are from 192K-3072K(for now must be identical for RX and TX). For VHF optimal is 768K sample rate, 1.5MHz BW. For HF 3072K sr and 40MHz bw. Higher sample rate are not working on my PC because there is no decimation downstream in DttSP library. My slower PC Q9300 quad core with additional USB 3.0 card can deal with 768K streams, faster R5 1500X up to 3072K. On faster PC I also played with SDR# plugin and with decimation 60Mb/s CPU usage is around 20%.
TODO: bug fixes and second RX/TX usage.
Any suggestion and help is appreciated.
