Description

Hello,
i want to change the timer intervall on the fly

i generate the intervall time with an formula

```
int myVar = 0;
double ticks = 60000000.0 / (myVar * 96.0);

void clock1()
{
// do stuff here
}

void setup()
{
Timer2.attachInterrupt(clock1);
}

void loop ()
{
if ( something == 1)
{
Timer2.start(ticks);
}

if ( somethingElse)
{
myVar = 120;
}
}
}
```
how can i update the changed value on the fly? do i have to stop and start the Timer again ?

Research direction

Start by reading the implementation and usage of Timer2.start and Timer2.attachInterrupt, then trace how the interval is stored and applied while the timer is running. Determine whether changing the calculated ticks value can affect an active timer or requires restarting it. Done means the supported behavior for updating an interval on the fly is clear and reproducible.
