C, C++ source code driver software for the Maxim Integrated MAX31725, MAX31726 thermostat : The MAX31725, MAX31726 temperature sensors provides temperature measurements with an accuracy of up to +-0.5°C. Extended format allows for high temperature readings up to 150°C. The MAX31725 can operate in a low powered mode by utilizing the shutdown and one-shot mode. MAX31725 supports two-wire serial, I2C bus communications in an 8-pin TQDFN 3x3 mm package.
