I am working with a device that has a relay on the 12v power supply to the micro controller that runs the device. Under certain unplanned circumstances this relay can chatter.
- What is the potential for memory corruption/unpredictable operation of the micro controller, and
- if the chattering relay causes problems for the micro controller, what is the most likely nature and effects of those problems.
The micro controller operates numerous other subsystems and has many digital inputs from sensors. The relay is located within inches of the micro-controller and its exposed I/O wiring.
