How shall write the code to return a value in an interrupt "up".
void loop() {
attachInterrupt(0, up, FALLING);
attachInterrupt(1, down, FALLING);
....
void up()
{
detachInterrupt(0);
int value = +1;
}

An ISR cannot return a value, you need to declare a global variable. Use the 'volatile' modifier and attempt to make all accesses to the variable atomic.
Example? url?
menola
volatile int i; // This is a global variable declared with the volatile modifier
void setup() {}
void loop() {}
hehe of corse!
