[FAQ] HDC3020: Is there an Energia or Arduino example available?

The HDC3 family of digital temperature and relative humidity sensors support multiple I2C addresses and the EVM for this device only supports one device at a time - is there a simple Arduino example to use which exercises more than one sensor from the same MCU?

    Yes, there are two simple examples available in either platform, which are attached here. 

    These exercise the HDC3 devices, using the four possible 7 bit I2C addresses (0x44, 0x45, 0x46 and 0x47); reading temp and %RH from the devices and sending data out over UART, for csv logging purposes (@115200, 8N1). These can be used with the HDC3020, HDC3021 and HDC3022.
