Is there any SPI example for CC2652 to communicate with sensor and get the data ?

Any re-usable code will be helpful.

Hi Ashok,

LM75A uses an I2C interface, not SPI. It will connect to CC2652 on SCL and SDA pins.

LM75A is an old product. We recommend that customers use TMP1075 instead. It has a lower price and better performance.

There is example software for TMP1075 and other LM75-like devices in the Sysconfig tool: https://dev.ti.com/sysconfig/index.html?product=ascstudio&module=/ti/sensors/tempsensor/TMP1075

I'm not aware of an accelerometer from TI. There is a third-party accelerometer on the BOOSTXL-SENSORS board and software examples for it using SimpleLink MCU like CC26xx. The same software library, known as Sensors and Actuators Plugin, has support for the TMP116 on the BOOSTXL-BASSENSORS board.

Thanks for your information.

Am using LIS2DW12 3rd party sensor 3 Axis Accelerometer MEMS, problem is i could not able to communicate and get the data from sensor through SPI.

Currently am using CC2652RB Launchpad.

I need some example code for SPI getting data from sensor.

I guess you need to contact ST to get sample code on how to communicate with the LIS2DW12. If you then have specific questions on how to achieve this with the CC26x2, TI can help you with that.
