Which spectrogram program? You will have to be more specific.

Here it is.

[https://github.com/gasparka/spectrogram](https://github.com/gasparka/spectrogram) has not been updated in 2 years. It was designed for an (Intel MAX 10 FPGA. So I would say that there is zero chance of this working on a board that was created after it stopped receiving updates with a different FPGA chip from a different manufacturer and a different development toolchain. gasparka/spectrogram used a frozen in time modified version of the official LimeSDR-Mini Gateware, LimeSuite, SoapyRemote, SoapySDR and gqrx - that is a lot of custom code. Could it all be updated and migrated to work on a larger FPGA (Lattice ECP5 44K Logic Gates) inside a LimeSDR-Mini 2.0 from the smaller FPGA (Intel MAX 10 16K Logic Gates) inside a LimeSDR-Mini, I’d say that it probably could, it just needs someone who owns a LimeSDR-Mini 2.0 with the knowledge, ability and desire to make it happen.

Hi, i am the maintainer. Port for mini 2.0 is planned, cant give any dates or promises though.

Thank you for your reply. I am looking forward to your good news.
