    Plotting Data From Arduino

    HelloIm using following Adafruit sketch to read and plot the data from themocouplebased on MAX 31855 device using Bridge Control Panel Idid receive plot ,set X axis as a time ,and Y axis as temperature readings. butinstead of temperature readings I getting triangle waveform with amplitude vary from 30 to 7710 (see attached images) , valuesrepresented in Bridge Control panel TABLE capture looks okay to me. It ispossible to adjust Y axis temperature readings scale to get scaled temperaturereadings ? Or there is something wrong in my data readings ?Source h and cpp files : https://github.com/adafruit/Adafruit_MAX31856Thank You #include <SPI.h>#include "Adafruit_MAX31855.h"int maxSO = 5;int maxCS = 6;int maxSCK = 7;int abc;//Create a MAX31855 reference and tell it what pin ...see more »HelloIm using following Adafruit sketch to read and plot the data from themocouplebased on MAX 31855 device using Bridge Control Panel Idid receive plot ,set X axis as a time ,and Y axis as temperature readings. butinstead of temperature readings I getting triangle waveform with amplitude vary from 30 to 7710 (see attached images) , valuesrepresented in Bridge Control panel TABLE capture looks okay to me.

    Plotting Data From Arduino

    I did receive plot ,set X axis as a time ,and Y axis as temperature readings. but I getting triangle waveform amplitude vary from 30 to 7710 (see image) , values represented in Bridge Control panel TABLE capture looks okay to me. It is possible to adjust Y axis temperature readings scale to get scaled temperature readings ? Or there is something wrong in my data readings ?

    Hello Im using following Adafruit sketch to read and plot the data from themocouple based on MAX 31855 device using Bridge Control Panel All set according to your instruction ,but there is no any chart data. Im new in arduino ,maybe Int abc; definition problem.Please advice if you have any idea how to resolve the problem.Source h and cpp files : https://github.com/adafruit/Adafruit_MAX31856Thank You #include <SPI.h>#include "Adafruit_MAX31855.h"int maxSO = 5;int maxCS = 6;int maxSCK = 7;int abc;//Create a MAX31855 reference and tell it what pin does whatAdafruit_MAX31855 kTC(maxSCK, maxCS, maxSO);void setup() { Serial.begin(9600); // The MAX31855 needs a little time to stabilize delay(500);}void loop() { Serial.print("C = "); Serial.println(kTC.rea...see more »Hello Im using following Adafruit sketch to read and plot the data from themocouple based on MAX 31855 device using Bridge Control Panel All set according to your instruction ,but there is no any chart data.
