An unofficial command line program which can control the DDS Signal Generator and Counter device known as the "Koolertron Upgraded 60MHz DDS Signal Generator Counter", cross-platform and written in Rust. https://crates.io/crates/signal-gen-cjds66-lib

Upload Arbitrary Waveforms to the GH-CJDS66 60MHz Signal Generator from Linux (proof-of-concept). For a better full-control program that's cross-platform, see: https://gitlab.com/defcronyke/signal-gen-cjds66
