I need help on capacitive touch interfacing with STM32F042x. Please suggest schematics and Gerber file for that.

Have a look at https://www.st.com/en/evaluation-tools/32f072bdiscovery.html - the documentation (UM, schematics) and code (in CubeF0 probably) which comes with it.

Also read the related application notes https://www.st.com/content/st_com/en/search.html#q=touch-t=resources-page=1
