Some checks are pending
Rust/sat-rs/pipeline/pr-main Build queued...
First version of asynchronix based mini simulator
- Basic simulator with 3 devices
- Can be driven via a UDP interface
- Design allows to drive the simulation via different interface in the future
  by using Request/Reply messaging.
