The lpspi_edma_b2b_transfer example shows how to use LPSPI driver in edma way:In this example , we need two boards, one board used as LPSPI master and another board used as LPSPI slave.The file 'lpspi_edma_b2b_transfer_slave.c' includes the LPSPI slave code.1. LPSPI master send/received data to/from LPSPI slave in edma . (LPSPI Slave using edma to receive/send the data)

The lpspi_functional_interrupt example shows how to use LPSPI driver in interrupt way:In this example , one lpspi instance used as LPSPI master and another lpspi instance used as LPSPI slave .1. LPSPI master send/received data to/from LPSPI slave in interrupt . (LPSPI Slave using interrupt to receive/send the data)

The lpspi_interrupt_b2b example shows how to use LPSPI driver in interrupt way:In this example , we need two boards , one board used as LPSPI master and another board used as LPSPI slave.The file 'lpspi_interrupt_b2b_master.c' includes the LPSPI master code.This example does not use the transactional API in LPSPI driver. It's a demonstration that how to use the interrupt in KSDK driver.1. LPSPI master send/received data to/from LPSPI slave in interrupt . (LPSPI Slave using interrupt to receive/send the data)

The lpspi_interrupt_b2b example shows how to use LPSPI driver in interrupt way:In this example , we need two boards , one board used as LPSPI master and another board used as LPSPI slave.The file 'dspi_interrupt_b2b_slave.c' includes the LPSPI slave code.This example does not use the transactional API in LPSPI driver.

The LPTMR project is a simple demonstration program of the SDK LPTMR driver. It sets up the LPTMRhardware block to trigger a periodic interrupt after every 1 second. When the LPTMR interrupt is triggereda message a printed on the UART terminal and an LED is toggled on the board.

The lpuart_edma Example project is to demonstrate usage of the KSDK lpuart driver.In the example, you can send characters to the console back and they will be printed out onto console in a group of 8 characters.
