Question

有人可以帮我在这里了解一下arduino库变量名，比如什么是tempTC，tempCJC，faultOpen，faultShortGND，faultShortVCC，

我很困惑。请帮忙！感谢

#include <MAX31855.h>

// Adruino 1.0 pre-defines these variables
#if ARDUINO < 100
int SCK = 13;
int MISO = 12;
int SS = 10;
#endif
int LED = 9;

// Setup the variables we are going to use.
double tempTC, tempCJC;
bool faultOpen, faultShortGND, faultShortVCC, x;
bool temp_unit = 1; // 0 = Celsius, 1 = Fahrenheit

// Init the MAX31855 library for the chip.
MAX31855 temp(SCK, SS, MISO);

void setup() {
  Serial.begin(9600);
  pinMode(LED, OUTPUT);
}

void loop() {
  x = temp.readMAX31855(&tempTC, &tempCJC, &faultOpen, &faultShortGND, &faultShortVCC, temp_unit);

    Serial.print(tempTC);
    Serial.print("\t");
    Serial.print(tempCJC);
    Serial.print("\t");
    Serial.print(faultOpen);
    Serial.print(faultShortGND);
    Serial.println(faultShortVCC);

  digitalWrite(LED, HIGH);
  delay(500);
  digitalWrite(LED, LOW);
  delay(500);
}

tempTC：从IC读取的热电偶值。
tempCJC：冷端补偿温度值。
faultOpen faultShortGND faultShortVCC：标志显示在读取温度时发生了任何这些故障。

所有这些都直接在MAX31855 IC中完成，通过SPI读取您发布的库。
