Average from sensor data strings

aureta

Hi, I am getting sets of data strings from a sensor that I would like to average as new data comes out.  Would the average library allow me to do this, if so how can I get individual data points using the ave.push function?, Thanks.

    Here´s the code. Waht I need to do is get an average for X number of outputs coming from each individual channel. Similarly I want to be able to print out the group of data being averaged.

    Thanks.

     

    #include <Wire.h>

    #include "Adafruit_TCS34725.h"

    /* Initialise with specific int time and gain values */

    Adafruit_TCS34725 tcs = Adafruit_TCS34725(TCS34725_INTEGRATIONTIME_101MS, TCS34725_GAIN_4X);

     

    void setup(void)

    {

          Serial.begin(9600);

               if (tcs.begin())

                   {              

                   Serial.println("Found sensor");

                   }

               else

                    {

                    Serial.println("No TCS34725 found ... check your connections");

                    while (1);

                     }

    }

    void loop(void)

    {

                 uint16_t r, g, b, c, colorTemp, lux;

                 tcs.getRawData(&r, &g, &b, &c);

                 Serial.print(r,DEC);  Serial.print(","); Serial.print(g,DEC);  Serial.print(",");

                 Serial.print(b,DEC);  Serial.print(",");  Serial.println(c,DEC);       

                 delay(1000);      

    }

  • Alejandro, yes you can use the averages library for this.

     

    Have a look at the example https://github.com/MajenkoLibraries/Average/blob/master/examples/AverageExample/AverageExample.ino

    You should be able to merge that in with your current code.

     

    Looking at how push works you can keep adding values and it keeps the last X and throws away the oldest values.
