S32K116 LSPI MasterTransfer

[Embedded_novice]

我想使用图中的函数进行SPI的异步传输，但是我将SPI配置为DMA传输后这个函数无法实现通信，是否意味着这个函数只能在interrupt模式下调用？

Hi,

you can used async transfer using DMA as well, just you need to test if it is completed using LPSPI_DRV_MasterGetTransferStatus or you need to have callback installed to get into it after transfer is finished.

You can refer to lpspi_dma_master_s32k116 demo for DMA usage, but blocking function is used there.
