cfsd-logic-lynx-state-machine

This microservice provides the state machine for Lynx. Receives messages from different microservices and sets the appropriate autonomous state and state specific behaviour.
The state machine decides if torque and brake request should be used based on current state.

• Senderstamp Offsets
  • GPIO: 1000
  • Analog: 1200
  • PWM: 1300

Build

AMD64: docker build -f Dockerfile.amd64 -t chalmersfsd/cfsd-logic-lynx-state-machine:v0.0.0 .
