Now a DMA has to be either "armed" manually or re-arm itself automatically, and you get interrupts everytime you got a full of half buffer. All this is configurable. in CubeMX. Thanks for your reply.

WebDMA0 triggers DMA1 to transfer a value from an array of coefficients to OP2 which completes the Multiply-Accumulate. DMA0 is set to size=1. DMA1 is set to the length of the coefficient array, "x". When "x" values have been MAC'd, DMA1 causes an interrupt which stores the result, clears the MAC result registers, and the whole thing starts over.

To start with, let’s go over the most common type of STM32 DMA peripheral and use it to send some simple audio data to the chip’s DAC peripheral. I’ll be using an STM32F303 core for these examples; something like a ‘ Nucleo-32 ‘ board or an ‘ F3 Discovery Kit ‘ should work.

In this example 2000 bytes will be transfered using DMA, Transmit Half Complete and Transmit Complete interrupts achieving the best performance. The first half of the transmit buffer is loaded with new data by the CPU in the Transmit Half Complete interrupt callback while the second half of the buffer is being transmitted by the DMA in the …
