TI_TMP116 Sample

Description

This sample application periodically takes temperature readings using the ti_tmp116 sensor driver. The result is written to the console. This sample also included the code to use the features provided by TMP117, which is a sensor similar to TMP116

Requirements

This sample needs a TI TMP116 or TI TMP117 sensor connected to the target board’s I2C connector.

Wiring

This sample is tested with Nucleo STM32F401RE board.

The sensor operates at 3.3V and uses I2C to communicate with the board.

External Wires:

Breakout GND pin <–> Nucleo GND pin
Breakout VCC pin <–> Nucleo 3V3 pin
Breakout SDA pin <–> Nucleo CN5-D14 pin
Breakout SCL pin <–> Nucleo CN5-D15 pin

Building and Running

In order to build the sample, connect the board to the computer with a USB cable and enter the following commands:

west build -b nucleo_f401re samples/sensor/tmp116
west flash

Sample Output

The output can be seen via a terminal emulator (e.g. minicom). Connect the board with a USB cable to the computer and open /dev/ttyACM0 with the below serial settings:

Baudrate: 115200
Parity: None
Data: 8
Stop bits: 1

The output should look like this:

Device TMP116 - 0x200010a8 is ready
temp is 26.7031250 oC
temp is 26.7109375 oC
