Operation
This demonstration uses the LCD on the MSP-EXP430F6989 LaunchPad to display temperature data. It
begins by querying the TMP107 bus for the last device in the bus. If the number of devices on the bus has
recently changed, or if new TMP107 devices are being used, hold the pushbutton S1 to initialize the bus
addresses instead. After either LastDevice query or AddressInit occurs, a global read operation is then
performed on the bus to retrieve temperature data from all TMP107 devices. This temperature data is
displayed sequentially on the LCD using the battery indicator bars to indicate (in binary) the current
device.
