  • dac_continuous_pdb_edma

    µVision AC6

    The demo shows how to use the PDB to generate a DAC trigger and use the DMA to transfer data into DAC buffer.In this example, DAC is first set to normal buffer mode. PDB is as DAC hardware trigger source and DMA would work when DAC read pointer is zero. When run the example, the DAC is triggered by PDB and the read pointer increases by one,every time the trigger occurs. When the read pointer reaches the upper limit, it goes to zero directly in the next trigger event.while read pointer goes to zero, DMA request will be triggered and transfer data into DAC buffer. The user should probethe DAC output with a oscilloscope to see the Half-sine signal.

  • dspi_edma_b2b_transfer_master

    µVision AC6

    The dspi_edma_b2b_transfer example shows how to use DSPI driver in edma way:In this example , we need two boards, one board used as DSPI master and another board used as DSPI slave.The file 'dspi_edma_b2b_transfer_master.c' includes the DSPI master code.1. DSPI master send/received data to/from DSPI slave in edma . (DSPI Slave using edma to receive/send the data)

  • dspi_half_duplex_edma_master

    µVision AC6

    The dspi_half_duplex_edma_transfer_master example shows how to use driver API to transfer in half-duplex way. In this example, one spi instance as master and another spi instance on the other board as slave. Master sendsa piece of data to slave, and receive a piece of data from slave. This example checks if the data received fromslave is correct.Besides, master will transfer in EDMA way.

  • dspi_half_duplex_edma_slave

    µVision AC6

    The dspi_half_duplex_edma_transfer_slave example shows how to receive and transmit data to master board.Notice: The SPI slave of this example uses edma mode. The data transfer size(not buffer size) is twice ofthe master's transfer size. The first half of the transmission will receive data, and the second half will senddata back to master, so the begain address of the receive buffer is &rxDataPolling[64].In this example, one spi instance as slave and another spi instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from master is correct. And slave will print what it received.
