Hi, I am using NUCLEO-64 STM32F401 and I have attached a serial EEPROM to I2C3. I am using the LL library calls to try to write to the EEPROM but I cant get the slave address to appear on the I2C bus. I do see the start pulse on the scope. Code below.

The code below gets stuck at --- while (!txBytes) txBytes=LL_I2C_IsActiveFlag_ADDR(I2C3);and the ADDR bit never gets read as set?==========================================void I2C_Write(uint8_t dataCount, uint8_t data){ uint8_t I2CAddrWrite = 0xa0;...

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?
