Heartbeat watchdog
A versatile watchdog and heartbeat traits for various monitoring purposes in mission-critical systems (processes, single threads etc).
The crate is a part of the RoboPLC project and works on Linux only. No other platforms support is planned, except bare-metal.
Communication
The crate provides out-of-the-box:
-
UDPsocket heartbeat/watchdog -
GPIOheartbeat/watchdog (requiresgpiofeature)
More communication methods can be added by implementing io::WatchdogIo and
Heart traits.
For high-level communication (e.g. TCP/IP) the edges are encoded as "+" for rising and "." for falling to simplify sniffing/debugging purposes.
Bare-metal
The crate has got integration with embassy for no_std
targets. Requires disabling defaults and enabling embassy feature.
Error detection
The following heartbeat errors are detected:
-
Timeout- no heartbeat edge change has been detected within the specified time -
Window- heartbeat edge change has been detected out of the time window -
OutOfOrder- heartbeat edge change has been detected out of order (e.g. for TCP/IP communication)
