HAL SMBUS on STM32L071xxx, how to set up correctly

I configured I2C SMBUS in cubemx and reimplement HAL_SMBUS_MasterTxCpltCallback, then I called MX_I2C1_SMBUS_Init() and HAL_SMBUS_Master_Transmit_IT(). After that i had no any events: not called callback and no any data transmited. In fact on sda and...

I am trying to setup DMA with ADC on stm32h747 even thoug conversion end DMA transfer never completes. The ADC's conversions are triggered by a timer (this part of the code works fine) and the DMA is supposed to write the data to memory.

Here is how I setup my DMA ; Enable Clock for DMA1Periph to memoryset memory and periph size to half wordset memory address increment and clear periph address incrementset circular modegive the flow control to the ADCSet DMAMUXSet DMA periph addressE...
