Operation
This demonstration uses the MSP application UART to report temperature data to the PC. The MSP
application UART is a virtual COM port that is made available by the LaunchPad. Monitor this COM port
using a terminal application, such as PuTTy. See
for an example of MSP application UART
output. The demonstration 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 then printed to the MSP application UART, and LED1 flashes to indicate
how many TMP107 devices were found.
