Hi everyone. While reading ST technical documentation i haven't realised whether there exists a simple way to find out which one of buffers is in use in interrupt routine without keeping count, some reliable way?

Thanks  #dma-double-buffer-memory-target

Hello,

I'm using the following command to determine which memory block has to be processed: DMA_GetCurrentMemoryTarget if( DMA_GetCurrentMemoryTarget(DMA2_Stream0) == 0 ) {    ... } else {    ... } Best.
