using code and adding Software Serial as an example:
// this example is public domain. enjoy!
//
www.ladyada.net/learn/sensors/thermocouple
#include "max6675.h"
#include <SoftwareSerial.h>
SoftwareSerial LCD1(0,12);
int thermoDO = 4;
int thermoCS = 5;
int thermoCLK = 6;
MAX6675 thermocouple(thermoCLK, thermoCS, thermoDO);
int vccPin = 3;
int gndPin = 2;
void setup() {
Serial.begin(9600);
// use Arduino pins
pinMode(vccPin, OUTPUT); digitalWrite(vccPin, HIGH);
pinMode(gndPin, OUTPUT); digitalWrite(gndPin, LOW);
Serial.println("MAX6675 test");
// wait for MAX chip to stabilize
delay(500);
}
void loop() {
// basic readout test, just print the current temp
Serial.print("C = ");
Serial.println(thermocouple.readCelsius());
Serial.print("F = ");
Serial.println(thermocouple.readFahrenheit());
delay(1000);
}
results in errors:
serialthermocouple.cpp.o: In function `__static_initialization_and_destruction_0':
C:\Users\TEVISC~1\AppData\Local\Temp\build3654529240356863777.tmp/serialthermocouple.cpp:9: undefined reference to `SoftwareSerial::SoftwareSerial(unsigned char, unsigned char, bool)'
C:\Users\TEVISC~1\AppData\Local\Temp\build3654529240356863777.tmp/serialthermocouple.cpp:9: undefined reference to `SoftwareSerial::~SoftwareSerial()'
This is a problem because my LCD display communicates via serial. =\
