setHighAlarmTemp() and setLowAlarmTemp() functions configure a device’s internal high and low temperature alarms in degrees Celsius. Wire - Two Wire Interface (TWI/I2C) for sending and receiving data over a net of devices or sensors.bool getWaitForConversion() function returns the value of the waitForConversion flag, which is useful when determining whether or not a temperature conversion is complete.setResolution() function sets the resolution of the DS18B20’s internal ADC to 9, 10, 11, or 12-bits, which correspond to 0.5☌, 0.25☌, 0.125☌, and 0.0625☌, respectively.There are many useful functions you can use with the DallasTemperature object.

Written by Limor Fried/Ladyada for Adafruit Industries, with contributions from the open source community. This example is for a 128x32 pixel display using I2C to communicate 3 pins are required to interface (two I2C and one reset).Īdafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

This is an example for our Monochrome OLEDs based on SSD1306 drivers. The following code should load: /*********
