Intervall Timer - stop and resuming

[michu]

Hey All

I've a question about the interval timer library. Compared to the Teensy 2 compatible TimerOne Library I miss a resume option. I saw that there are two private methods called

    static void enable_PIT();
    static void disable_PIT();

Can I define them as public and call them to stop and resume my isr? or is this a bad idea? More details about the use case, I need to drive a clock spi line in a ISR - sometimes i need to shift out also data on the spi line and then I need to stop the ISR.

Cheers and thanks for your work

Use the end() function to stop the timer. When you want to start it again, use begin().

Thanks for your reply paul. I saw that this are the regular begin / end calls - but I had to call those begin end calls often (up to 100 times per second) and I'm afraid using those calls will slow down my code. I just want to make sure the isr routine is not running during one function is called. to illustrate my use case, take a look at my code at https://github.com/neophob/PixelCont...PD6803.cpp#L83.
