    The cmt example shows the simplest way to use CMT driver.In this example, the CMT is work as Time mode and used to modulation 11 bit numbers of data.The CMT is configured to generate a 40000hz carrier generator signal through a modulator gateconfigured with different mark/space time period to represent bit 1 and bit 0. The modulated data rate is 9600.Note, The end of cycle interrupt provides a means for the user to reload new mark/space valuesinto the modulator data registers. Modulator data register updates will take effect at the end of the current modulation cycle. The CMT internal down-counter and space period register areupdated at the end of every modulation cycle, irrespective of interrupt handling and the stateof the interrupt. so please make sure the IRQ handler process is shorter than the modulationcycle to ensure the new mark/space counter is prepared before each end of modulation cycle.

    The DAC / ADC demo application demonstrates the use of the DAC and ADC peripherals. This application demonstrates how toconfigure the DAC and set the output on the DAC. This demo also demonstrates how to configure the ADC in 'Blocking Mode'and how to read ADC values.

    The dac_basic example shows how to use DAC module simply as the general DAC converter.When the DAC's buffer feature is not enabled, the first item of the buffer is used as the DAC output data register.The converter would always output the value of the first item. In this example, it gets the value from terminal,outputs the DAC output voltage through DAC output pin.

    The dac_buffer_interrupt example shows how to use DAC buffer with interrupts.When the DAC's buffer feature is enabled, user can benefit from the automation of updating DAC output by hardware/software trigger. As we know, the DAC converter outputs the value of item pointed by current read pointer. Once the buffer is triggered by software or hardware, the buffer's read pointer would move automatically as the work mode is set,like normal (cycle) mode, swing mode, one-time-scan mode or FIFO mode.In this example, it captures the user's type-in operation from terminal and does the software trigger to the buffer.The terminal would also display the log that shows the current buffer pointer's position with buffer events.

    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_half_duplex_edma_master

    Keil Studio, 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.

    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.
