How to proceed Coding for getting Temperature Reading from STS35 interface with stm32?

BT.2 · ‎2023-01-24

I am using STS35 DIS and Nucleo-WB55RG board and wants to know how to get temperature readings from the sensor. I am using STM32CubeIDE for programming. It would be helpful for my learning and proceed with my project. if you share some example coding for this.

Hello @BT.2 ,

First of all, please check sensor pins : (SCL / SDA)

The communication must be with I2C protocol .
Then Look at the max frequency of the I2C communication : "The clock frequency can be freely chosen between 0 to 1000 kHz"

Communication with frequencies up to 400 kHz must meet the I2C Fast Mode.
Communication up to 1 MHz are supported (Fast Mode Plus)

Check the I2C address for the sensor :

Finally, open STM32CubeMx and start the configuration. :D

Maybe this example (I2C_Master.c) and related STTS751 temp sensor in the B_ANALOG_ENV folder may help you for component bringup with I2C GPIO SW bit banging.
