-Faster analog reading: no wake up time, ADC stay on all the time.
-Free up MCU: micro controller do not wait for conversion, it is done in background and result conversion data is render trough interrupt routine.
-Fast sample rate: conversion are time with ADC clock set by prescaler, clock going from 164KHz and 48Mhz.
-Enable the usage of pin 52, 20 and 21 for another analog input.
-Enable internal temp sensor
-Could activate any wanted number of analog pin.

-Final conversion sample time not known. Some test have been made with micros() chronos to give an estimation of the sample rate but the result given by the ADC_sampleRate() function are for reference only, not for critical timing use. -Disable and re-enable function are not fully tested yet.
-Temp sensor is not accurate: it is more to be use for alarm for extreme temp (-40, +60C ). A calibration routine could also be added.

-Add preinstantioated object -Add suppot to use SAM3x AD08, AD09 (SDA0 pin 20, SCL0 pin 21 ) -Fix conlict with I2C0 and analog pin 8 and 9 -Fix begin with only one argument

-Fix begin(...) arguments cast compile error when mixing Ax analog pin and integer -Add function to return approximative ADC sample rate

ADC_SEQR is a rapper of static member variable and function so user could or not create an instance or use it with scope operator

-The user could create an instance if wanted:

~~Adc_Seqr adc_seqr;~~

If an instance of the library is created, any function could be call with the "." operator. Without, use scope "::" operator: A preinstantiated object is already been set:

Adc_Seqr.begin();

-First include header:

#include <ADC_SEQR.h>

-Then, setup the sequencer, two begin function are available: -without argument: enable all adc channel A0 to A11, pin 52, pin 20, pin 21 and internal temp sensor.

ATTENTION

-if you enable analog pin 20 or 21, I2C0 will be disale

-Also, pin 20 and 21 have harware 1k5 pullup resistor, it have to be in design consideration.

void setup(){
	Serial.begin(9600);
	Adc_Seqr.begin();
}

-Or, active only the pin wanted, begin function could take any number of argument from 1 pin to all of them. order do not matter.
Argument could be in analog pin name or integer. pin 52 is only take integer argument. Internal temp sensor have a dedicated constant.

void setup(){
	Serial.begin(9600);
	Adc_Seqr.begin(A0, 8, 4, A6, INTERNAL_TEMP);
//other configs to come before closing setup

-Other configuration could be set, analog resolution, and prescaler to aduste ADC clock:

analogReadResolution(10); //default is 12
prescaler(127); //0-255
// ADC clock = (Master clock 84MHz) / 2(prescaler+1)

-And proximative analog sample rate can be given in Hz:

int adcSampleRate = Adc_Seqr.ADC_sampleRate();

-If wanted, ADC config and some register info could be printed:

	Adc_Seqr.printSetup();
} //now void setup() is ready to be close

-To read an input call read(pin) function, support the same input than begin function:

int a = Adc_Seqr.read(0);
int b = Adc_Seqr.read(A6);
int b = Adc_Seqr.read(52);

-get the internal temp, it is a global function, no scope operator needed:

int internalTemperature = internalTemp();

-disale and re-enable the sequencer

Adc_Seqr.disable();
Adc_Seqr.enable();
