This article aims to introduce the application of DMA2D mode through the STM32H563 development board. The so-called DMA 2D mode means that the DMA can dynamically adjust the addressing mode and capability of the DMA by setting the intra-block addressing offset and the block addressing offset in advance. In other words, when DMA performs data
