To save some reading, this uses a combination of an FPGA and kernel (which I think is in Rust) to generate a realtime buffer that is programmed using a mix of compiled-realtime python and plain python via a RPC system.
We can talk instead about how the requirements to run slightly less simple near-hard real-time controllers are really heavy in terms of money, effort and .. weight. This tool may actually help to streamline the software part, potentially being a substitution in certain cases to i.e. Matlab Coder or similar tools.
