Hi, i need help getting started with the use of DMA. I cant get my mind right when trying to use SDRAM with DMA. The only thing i want to do is to take a generated buffert of values and store the buffert in the sdram. Then continue to store new generated buffert data to the sdram until a set a flag then i will read the data from the sdram to a different buffert that it will send to the sdcard. So how do i use the DMA woth SDRAM, a function or so to call when i want to write to sdram and a function when reading from it. How would these look like??
