This is a yet another library for communication with Microchip MCP9808 temperature sensor on Arduino boards. The I2C I/O operations are done using Arduino Wire library.

The library provide functions for:

• reading the temperature sample;
• changing the resolution of the temperature measurement;
• switching between the continuous conversion and shutdown mode of operation.

Alarms or interrupts are not supported.

• AVR (Arduino boards based on Atmega328p microcontroller);
• ESP32C6 (boards based on ESP32C6 and supported by the latest Arduino ESP32 APIs by Espressif System).

• begin() - the function initializes the connection with the sensor and prepares for I2C I/O operations. The default I2C address is 0x18. It configures the sensor to perform a continuous temperature sampling with resolution of ±0.25°C. as default settings. Use the arguments of the functions to begin with a different mode and resolution. This function should be called only once.

• setModOfOperation() - switch between the different mods of operation: shutdown (the sensor is still accessible via I2C bus for configuration but does not perform temperature measurements) and continuous temperature measurements.

• setResolution() - change the resolution of the temperature measurement by providing one of the four possible values as an argument.

• readTemperature() - use this function to get the current temperature value in °C.
