Getting Started with STM32 I2C Example

Note that we need to first send out a write command from the STM32 to the TMP102 with 1 byte that contains the address of the temperature register in the TMP102 (address 0x00). We immediately follow that with a read command where we read 2 bytes from the TMP102. These 2 bytes will contain the temperature data.
