Int2Type

struct Int2Type

template<int I>
struct Int2Type< I >

Enables you to instantiate a template based on an integer value.

For example, this is used in StateVariable.h to choose a different next() function for each kind of filter, LOWPASS, BANDPASS, HIGHPASS or NOTCH, which are simple integer values 0,1,2,3 provided to the StateVariable template on instantiation. Fantastic! It's in C++11, but not yet available in avr-gcc. See "c++ enable_if"

Function Documentation

BPMtoMillis()

unsigned int BPMtoMillis

(

float

bpm

)

Given a power of 2, work out the number to shift right by to do a divide by the number, or shift left to multiply.

Parameters

a	power of 2, or any other number for that matter

Returns

the number of trailing zeros on the right hand end Convert BPM to milliseconds, which can be used to set the delay between beats for Metronome.

Parameters

bpm	beats per minute
