/*! \file readme.txt \brief description of DMA ram to ram */ /* Copyright (C) 2017 GigaDevice 2017-06-06, V1.0.0, firmware for GD32F3x0 */ This example is based on the GD32350R-EVAL board, it provides a description of how to use DMA channel(1 to 4) to transfer data from RAM to RAM.DMA Channel(1 to 4) is configured to transfer the contents of data buffer stored in "source_address" to the reception buffer declared in RAM(destination_address1~destination_address4). The start of transfer is triggered by software. At the end of the transfer, a comparison between the source and destination buffers is done to check that all data have been correctly transferred.If transfer correctly the corresponding LED light.If transfer do not correcly,the corresponding LED is off.
