When using the Low Level libraries for the STM32L072RB I2C bus ( stm32l0xx_ll_i2c.h) I have a function available called LL_I2C_HandleTransfer. I have ported the code to STM32F401RE and the library ( stm32f4xx_ll_i2c.h) does not have this function?

I was wondering why the library function  LL_I2C_HandleTransfer is not available in th F4 LL library?

    Hello @DCull.1​ ,

    The I2C IP for STM32L0 is not the same as STM32F4, and the I2C implementation is different.

    You can refer to the UM1725 Description of STM32F4 HAL and low-layer drivers, which gives you an overview of low-layer drivers and a detailed description of each peripheral driver: configuration structures, functions, and how to use the given API to build your application.

    Best Regards,
