I need / want to monitor multiple inputs using state machine triggered by interrupts.
I could build an individual ISR for each input, but I wonder if there is another way.
For example I could modify attachInterrupt to accept the input as an index or have an array of ISR functions.
Any other thoughts?
Thanks

Before thinking about this at the level of the Arduino IDE, I suggest to spend some time with the data sheets for the mpu of interest and understand how interrupts work on the machine level. In most cases there is a unique jump vector for each hardware interrupt source. Pin change is an important exception.
Great point, time to get serious and get away from "high level" programming.
I need to do some other work at "low level" ( fluorescent display ) and I will do that first.
I can "see" the results on the display if I am doing it right!
Thanks

PS
WInterrupt source gets down to register level, but run into snag - callback cannot have parameter added as is. But it looks promising.
If you are using an AVR. Get a copy of the avr-libc user manual.

If you are using an ARM mcu try and get a copy of the user manual for the C library being used. I don't know which C lib they use.
