My question is about general/recommended practices for interrupt coding.
I am using the dsPIC30F2010 and using INT0, INT1, and TMR1 interrupts.
INT0 and 1 are external interrupts based on sensor input (IR switch)
I am using timer 1 interrupt on period match for a delay.
My config allows for nested interrupts.
Is it generally ok to have about 30 lines of code inside the interrupt 
routine? On INT0 I am decrementing a register several times with a delay 
which uses TMR1 interrupt between each decrement.
Should I be calling another routine from the isr to do this?
Any advice welcome!
