Texas Instruments TMP116METER-EVM User Manual

The TMP116METER-EVM provides the user with an easy-to-read LCD screen while using the TMP116 for
measurement of ambient air temperature. The EVM measures 1.83 in × 1.45 in, so the system is fitted to
a small form factor for further convenience in space-constrained environments. The onboard
microcontroller (MCU) communicates with the temperature sensor using I2C communication protocol and
displays the measurement onto an LCD through SPI protocol.

1 Introduction
The TMP116METER-EVM comes pre-loaded with firmware that ensures successful operation upon
connection of the coin cell battery. Because the MCU is flashed using JTAG protocol, the test, reset, and
ground pins are broken out to a three-pin header for the user to have the option to flash the
MSP430FR5969 MCU. The device features three push-buttons: Button S1 functions to perform RESET,
S2 switches the temperature display format on the display (Celsius or Fahrenheit), and another button
(S3) can be programmed by the user. Test points are provided for the user to probe the clock and data
signal lines corresponding to I2C data transfer in addition to power and ground probe locations.
