How can I use NX(I2C master) to communicate with STM32(I2C slaver)?

I hope someone can offer me some suggestions :
I code the stm32 i2c slaver and it works correctly. Now i need to transfer some data to NX by I2C. The first time I use this Linux development board, I want to know whether I need to start from the driver layer for I2C communication, or whether there are relevant methods in the direct application layer that can be called. Pls…thanks.

Sorry for the late response, is this still an issue to support? Thanks
