s32k312 lpspi mode

[fengba_360]

Hello, if I don't want to use the DMA+SPI transmission method and instead only use the SPI polling method, do I only need to initialize SPI and call the data sending function? Like so

step1： Lpspi_Ip_Init(&Lpspi_Ip_PhyUnitConfig_SpiPhyUnit_0_Instance_0);

step2：Lpspi_Ip_SyncTransmit(&Lpspi_Ip_DeviceAttributes_SpiExternalDevice_0_Instance_0,

TX, RX, len, SPI_TIME_OUT);

Whether interrupt configuration is also needed when using SPI in polling mode?

IntCtrl_Ip_EnableIrq(LPSPI0_IRQn);
IntCtrl_Ip_InstallHandler(LPSPI0_IRQn, Lpspi_Ip_LPSPI_0_IRQHandler, NULL_PTR);

Hi @fengba_360 

I suggest you check out the SPI sample codes provided with the RTDs. The sample codes show the use of the Flexio_Spi and the LPSPI drivers to transfer data between the Flexio_Spi and Lpspi physical units, one configured in interrupt mode with DMA and the other in polling mode.
