GPIO40-43 interrupt availability

Thu Aug 09, 2018 12:35 pm

Hi all,

I am using a CM3 on a project, and I was using pigpio for interrupts on GPIO28-31. I recently had to add GPIO40-43 and I learned that pigpio will not handle interrupts on pins > 31.

Is this a hardware or software limitation? I believe it is a software limitation. if so, can anyone point me to another library that might be able to handle interrupts on all of the GPIO mentioned above? I had tried using RPI.GPIO but that interrupt handler seemed to miss some edges...

Thanks!
