The data is output in a signed 14-bit, SPI-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1800°C and as low as -270°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from -200°C to +700°C for K-type thermocouples.\n\nLibDriver MAX31855 is a full-featured driver for MAX31855, launched by LibDriver.It provides temperature reading and additional features. LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example basic](#example-basic)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver MAX31855 source files.\n\n/interface includes LibDriver MAX31855 SPI platform independent template.\n\n/test includes LibDriver MAX31855 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver MAX31855 sample code.\n\n/doc includes LibDriver MAX31855 offline document.\n\n/datasheet includes MAX31855 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
