Hi STM32g474 do not have the function "HAL_DMAEx_MultiBufferStart_IT()", i want to realize two DMA buffer for ADC，are there any examples for ping-pong buffer？ Thank you

The STM32G4 doesn't have the double-buffer DMA capability (DBM=1) that some other families do.

You can use a single buffer and use the HT and TC interrupts to process each half of the buffer.
