Logging¶

There is the "trouble" function implemented for sensemux.
It should be integrated to an heartbeat class.

• good (double)
• crytical error (fast blink)
• fatal error (slow blink)
• temporary error/ trouble (fast blink - off 1Hz) (goes away)

There are weak c functions: * trouble() * critical() * fatal()
Usecases:

• invalid eeprom causes "critical"-state
• Not being able to sen CAN messages causes "trouble"
• fatal: the application can not run for some reason but the led should work; e.g. a reception buffer is full
• exception: Don't even try to run any more. e.g. memory error.
