Unable to include X-CUBE-MEMS1 in I2C example project

I am encountering a build failure in the I2C_OneBoard_Communication_PollingAndIT_Init project after integrating the X-CUBE-MEMS1 software expansion pack.

Hello @kclauah ,

Check if the header files are missing from the generated project structure and ensure that all necessary files are included in the build.

How to integrate the X-CUBE-MEMS1 package with your project

Thank you for your suggestion and for pointing me to that guide. I appreciate you taking the time to help.

I followed the steps in the guide you shared, but unfortunately, the project still failed to build.

After some more digging, I eventually found the solution. The issue was that the X-CUBE-MEMS1 pack requires I2C DMA to be enabled, which was not the default configuration in the base project. I found the answer in this forum post: 

https://community.st.com/t5/stm32-mcus/how-to-configure-the-gpdma/ta-p/49412

Once I enabled the appropriate I2C DMA channels in CubeMX and regenerated the code, the build errors were resolved and the project now compiles successfully.
