Hallo Luap,
Please notice that it is highly recommended to use the LPCOpen packages for development work instead of the CMSIS code packages, you can download the LPCOpen package from this page:
LPCOpen Software for LPC11XX|NXP
You could use the periph_i2cm_interrupt or periph_i2cm_polling projects as base for your application.
As a recommendation, it would be better if you could post your questions in English as it will be easier for other community members to understand and contribute to your question.
Hope it helps!
Best Regards,
Carlos Mendoza
