Multiple GPIO with Interrupts on a single socket


#1

I have a Raptor and need to read a linear encoder. I am using quadrature so I need two interrupt capable GPIOs. It appears no sockets have two interrupt capable GPIOs. Do I need to put breakouts on two sockets to get the capability I need?


#2

The socket specs only guarantee pin 3 as interrupt capable, but you have to look at the individual datasheet for MCU on the particular mainboard. For example Cerb family has interrupts on all the pins with some constraints (you can use only one interrupt on the pins withe same number from different ports for example). It depends.


#3

Thanks, I will continue investigating then.
