Hi There,While reading the data from I2C, I see that the master is missing to send NACK.Some fixed was done in https://github.com/STMicroelectronics/STM32CubeF4/issues/139 but those fixes are there in the code. But still sometime i see that NACK not ...

Hi There,Yes HAL_I2C_Mem_Write works for me.I removed the I2C pins from the .ioc file and added back again without renaming the label name on SDA and SCL.Now i can see that it can send exactly the 6 bytes. But looks like there is no NACK and SCL is p...

Hi Evangelist,Calling a write function to write about 6 bytes. But it keeps sending contineously a lot of data.HAL_StatusTypeDef ret = HAL_I2C_Mem_Write_DMA(&hi2c1, (20 << 1) | 0, 4, 1, &to_reg[0], 6);

Hi @Imen.D , After a long run test, what i found was not the HAL_BUSY. It is about the HAL_ERROR. Seems like BTF flag was not set.I put the break point in below code. What could be the reason of BTF not been set? Is it noise on the signal or somethin...

Hi @Imen.D ,I think i already have STM32CubeF4 V1.28.0 version.
