Hi everyone:
As a title,I use dma Usart Rx for DMA1 Channel 3,but at the same time, I also use Spi Tx for DMA.So , I must remap Usart Rx from DMA1 Channel 3 to DMA1 Channel 5.I try to use this function SYSCFG_DMAChannelRemapConfig(SYSCFG_CFGR1_USART1RX_DMA_RMP,ENABLE); and I correct the channel 3 to channel 5,but it didn't work.
Could any one knows how to use DMA Channel remapping, and please provide details, thanks.
