## Summary
This is a Library for MAX31855,the function is to read the temperature by thermocouple.
If warming 'ImportError: No module named wiringpi' in raspberry, you need to execute  `pip install wiringpi`.

## Methods

### Arduino
```C++

#include <DFRobot_MAX31855.h>
/*
 * @brief The constructor
 */
DFRobot_MAX31855();

/*
 * @brief Detect I2C device.
 *
 * @return true if execute successfully, false otherwise.
 */
bool scan();

/*
 * @brief Read the temperature.
 *
 * @return temperature if execute successfully.
 */
float readCelsius();
```
### micropython
```python

import MAX31855

# @brief The constructor.
#
# @param i2c I2C object.
MAX31855(i2c)

# @brief Detect I2C device.
#
# @return True if execute successfully, False otherwise.
scan()


# @brief Read the temperature.
#
# @return temperature if execute successfully.
readCelsius()
```
### Raspberry Pi
```python

import DFRobot_MAX31855
#
# @brief The constructor.

DFRobot_MAX31855()


#  @brief Read the temperature.
# 
#  @return temperature if execute successfully.
readCelsius()
```
