voidNdisMCompleteDmaTransfer( _S, _H, _B, _O, _L, _M_ ); 參數 _S 呼叫端提供的變數指標,此變數會傳回 DMA 傳輸的最終狀態,可以是下列其中一項: NDIS_STATUS_SUCCESS 數據已傳輸並排清至主機記憶體或裝置,以維護數據完整性。 NDIS_STATUS_RESOURCES ...
I configure I2S to transmit/receive in DMA mode and circular buffer. I need to get an ISR on HalfComplete and Complete transfer. HAL_I2SEx_TxRxHalfCpltCallback is fired on half complete transfer, but HAL_I2SEx_TxRxCpltCallback is not. Is there a way to get an IRQ on transfer ...

I’m using s32k148 and configured an spi slave channel with dma transfer. It looks like I have to know in advance the length of data to be received. If I try to set it to receive some max buffer size value and the spi master sends less data, the slave continues the ...
aThe main purpose of the DMA triggers is to synchronize the peripherals with the transfer rate. For instance, when using the USART at 9600 baud, the DMA should not be triggered more often than the transfer complete flag is set. DMA触发器的主要目的将与转学比例同步外围设备。 例如,当使用USART...
