Detailed Description

Data logger library Designed for the ALog Modules should work for any Arduino-based board with minimal modificiation Goals: (1) Manage logger utility functions, largely behind-the-scenes (2) Simplify data logger operations to one-line calls

Written by Andy Wickert, 2011-2017, and Chad Sandell, 2016-2017 Started 27 September 2011

Designed to greatly simplify Arduino sketches for the ALog and reduce what the end user needs to do into relatively simple one-line calls.

Function Documentation

read_Aref()

float read_Aref

(

)

Read the analog (ADC) sensor reference voltage from EEPROM, return float.

ADC == analog-digital comparator EEPROM = permanent memory (persists after shutdown) See: https://www.arduino.cc/en/Reference/EEPROMGet

Example:

float Vref;
Vref = alog.readAref();

save_Aref()

void save_Aref

(

float

_V

)

Saves a float as the reference voltage for the ADC ("Vref") to the EEPROM

ADC == analog-digital comparator EEPROM = permanent memory (persists after shutdown) See: https://www.arduino.cc/en/Reference/EEPROMPut

This function is only called rarely, as this value is typically measured only once.

Parameters

_V	reference voltage, ideally measured under load [V]

Example:

// Measuring 3.297V with a calibrated multimeter between 3V3 and GND
// Then:
alog.saveAref(3.297);
