#110979 - Interrupts
Responding to: ???'s previous message
hi,

Ian Bell said:
I notice your circuit feeds an interrupt. One possible problem is that the piezo oscillates and produces a fast series of interrupt pulses.


Yes, it does. They are debounced by software.
It seems that I should use full isolated DC/DC converter to produce separate supply for input circuit as Diego suggested. But this is expensive solution and more questions come then.

Regards,
Oleg
