stm32中 DMA1有7个通道,DMA2有5个通道。DMA挂载的时钟为AHB总线,其时钟为72Mhz,所以可以实现高速数据搬运。 stm32的DMA1通道一览表 stm32使用DMA的相关操作: 1、DMA的配置 void DMA_Configuration(void){ DMA_InitTypeDefDMA_InitStructure; //DMA设置: //设置DMA源:内存地址&串口数据寄存器地址 //方向:内存...
Hi, I want to send a 192 bit wide stream of data from IO pins to the SDRAM using a FIFO and DMA configuration. is it a sensible solution (or even possible) to use the A-ST DC FIFO with '64 bits pr symbol' and '3 symbols pr beat', and a SGDMA with 64bit width to read ...
