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 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)

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_polling_transfer_slave example shows how to receive and transmit data to master board.Notice: The SPI slave of this example uses interrupt 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 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.

The dspi_interrupt_b2b example shows how to use DSPI driver in interrupt way:In this example , we need two boards , one board used as DSPI master and another board used as DSPI slave.The file 'dspi_interrupt_b2b_master.c' includes the DSPI master code.This example does not use the transactional API in DSPI driver. It's a demonstration that how to use the interrupt in KSDK driver.1. DSPI master send/received data to/from DSPI slave in interrupt . (DSPI Slave using interrupt to receive/send the data)

The dspi_interrupt_b2b example shows how to use DSPI driver in interrupt way:In this example , we need two boards , one board used as DSPI master and another board used as DSPI slave.The file 'dspi_interrupt_b2b_slave.c' includes the DSPI slave code.This example does not use the transactional API in DSPI driver.

The E-Compass demo application demonstrates the use of the FXOS8700 sensor. The tilt-compensated algorithm calculatesall three angles (pitch, roll, and yaw or compass heading). You can open the mex file with MCUXpresso Config Tool to do further configuration of pin, clock and peripheral.

The EDMA memory to memory example is a simple demonstration program that uses the SDK software.It excuates one shot transfer from source buffer to destination buffer using the SDK EDMA drivers.The purpose of this example is to show how to use the EDMA and to provide a simple example fordebugging and further development.

The FTM project is a demonstration program of generating a combined PWM signal by the SDK FTM driver. It sets up the FTMhardware block to output PWM signals on two TPM channels. The example also shows the complementary mode of operationand deadtime insertion.On boards that have 2 LEDs connected to the FTM pins, the user will see a change in LED brightness.And if the board do not support LEDs to show, the outputs can be observed by oscilloscope.

The FTM project is a demonstration program of the SDK FTM driver's dual-edge capture feature.This feature is available only on certain SoC's.The example sets up a FTM channel-pair for dual-edge capture. Once the input signal is received,this example will print the capture values and period of the input signal on the terminal window.
