    Hi Monzur,

    Attached one STM32F334R8 DMA Interrupt example. 

    Like any other Interrupt service routine, You write your logic(read/write) inside a compound block and enable the the compound block with DMA channel interrupt. Memory access call back will be executed as soon as the interrupt triggers.

    In the attached example.

    - Initialize the ADC1 and enabled it 

    - Triggered the ADC using PWM1

    - ADC result captured inside DMA Interrupt call back.

    - Updated the monitor buffer with result.

    I will share you more example with detailed step soon.

    Regards

    Sreejith
