ISR on counter value in quadrature mode

0 votes

We're using a BL4S200. Is there a way to have an ISR called whenever a counter reaches a given 'match' value in quadrature mode? It seems possible for regular counters, but not quadrature ones.

Thank you

I'm not aware of an ISR for that. I see in the library that there's an BL_IER_DQE flag to addISR(), but I'm uncertain as to how it works (DQE = Decrement/Quadrature/End).

That product makes use of a "Rabbit IO" (aka "RIO") chip. Perhaps reading up on the chip's capabilities will help in understanding the code library and what it can and cannot do.
