from the ds you posted, i cannot say, what to do better.

now lets stop  to play blind cow . 🙂

so look, what drivers exist and learn/copy from them :

here sensirion gives driver for their sensor:

https://github.com/Sensirion/embedded-i2c-scd30

and many others...(also in c++, rust etc.)

https://github.com/paulvha/scd30

https://github.com/sparkfun/SparkFun_SCD30_Arduino_Library

https://github.com/RequestForCoffee/scd30

https://github.com/adafruit/Adafruit_SCD30

https://github.com/Seeed-Studio/Seeed_SCD30

https://github.com/watterott/CO2-Ampel

https://github.com/sinewave-ee/scd30-rs

the driver by sensirion should show you, what to do.

Hi,

Finally worked!!!!!!!!!!!!!

I was actually referring to the first link only last time when I told you about the pattern..

as planned I only replaced/used the same flow...just replace and got working on STM32F103C8..attached is the zip file...this will also work for C6

Hi,

Let me be honest in accepting that I am beginner to STM environment and its IDE...but definitely not the experience..In the current domain I was trying to help out from what my team had done.

Agree that name of the file did not change as we were trying out different projects at same time..

sorry if this has caused a concern and would rectify the same...the reason request to help us is raised so that there might not be a single solution to a problem.and would like to take help from those who are experienced ...will keep up the way forum wants ..Thanks

regards

Ravi
