Utility functions, and debugging

Detailed Description

Utility functions.

Includes functions for debugging and profiling high frequency code with an oscilloscope when serial is too slow, some miscellaneous functions used internally by Mozzi, python scripts for converting or generating sound tables, and assorted meta-programming utils.

Files
file	char2mozzi.py
	A script for converting raw 8 bit sound data files to wavetables for Mozzi.

Classes
struct	IntegerType< BYTES >
	Provides appropriate integer types that can bit the given number of bytes on this platform (at most 64). More...
struct	Int2Type< I >
	Enables you to instantiate a template based on an integer value. More...

Functions
void	setPin13Out ()
	Set digital pin 13 to output for testing timing with an oscilloscope.
void	setPin13High ()
	Set pin 13 high for testing timing with an oscilloscope.
void	setPin13Low ()
	Set pin 13 low for testing timing with an oscilloscope.
constexpr uint8_t	trailingZerosConst (unsigned long v)
	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. More...

IntegerType

struct IntegerType

template<uint8_t BYTES>
struct IntegerType< BYTES >

Provides appropriate integer types that can bit the given number of bytes on this platform (at most 64).

Definition at line 20 of file IntegerType.h.

Public Types
typedef IntegerType<(BYTES< 8) ?(BYTES+1) :8 >::unsigned_type	unsigned_type
typedef IntegerType<(BYTES< 8) ?(BYTES+1) :8 >::signed_type	signed_type

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"

Definition at line 40 of file meta.h.

Public Types
enum	{ value }

Function Documentation

trailingZerosConst()

constexpr uint8_t trailingZerosConst ( unsigned long  v )

constexpr

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
