Hello,

Is is possible to monitor a shutdown in PSOC 5 ?

Currently I read several VMON voltages. 

How can I know exactly when PSOC 5 is shutting down ?

Thank you,

Zvika

Zvika,

There are at least two ways to detect if the PSoC5 has shut down:

  • Place a current meter on the VDD before it enters the PSoC.  At shutdown the current should be at it's lowest level.
  • In your code, you could assign an unused GPIO pin to be an output that indicates shutdown.  Before you enter shutdown, you set it to 1.  Exiting shutdown you set it to 0.  

There are other non-direct ways to detect shutdown but not knowing your application, I can't advise.
