Hi frank,
Please refer the edma_transfer_s32k144 example in S32SDK S32K1xx RTM v3.0.x.
The purpose of this driver example is to show you how to use the eDMA in the following transfer scenarios for the S32K144 MCU with the S32 SDK API.
- Single block memory-to-memory transfer
- Loop memory-to-memory transfer
- Scatter/gather memory-to-memory transfer
- Memory-to-peripheral transfer (this feature is implicitly used with the LPUART driver)
- Peripheral-to-memory transfer (this feature is implicitly used with the LPUART driver)
The LPUART_DRV_SendData will Start the transmission process using DMA
Best Regards,
Robin
