The i2c_functional_interrupt example shows how to use I2C functional driver to build a interrupt based application:In this example , one i2c instance used as I2C master and another i2c instance used as I2C slave .1. I2C master send data to I2C slave in interrupt . (I2C Slave using interrupt to receive the data)2. I2C master read data from I2C slave in interrupt . (I2C Slave using interrupt to send the data)3. The example assumes that the connection is OK between master and slave, so there's NO error handling code.

The i2c_interrupt_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer with interrupt:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The i2c_interrupt_b2b_transfer_slave example shows how to use i2c driver as slave to do board to board transfer with interrupt:In this example, one i2c instance as slave and another i2c 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 slave is correct.

The i2c_polling_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer using polling method:In this example, one i2c instance as master and another i2c instance on the other board as slave. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from slave is correct.

The i2c_polling_b2b_transfer_slave example shows how to use i2c driver as slave to do board to board transfer with a polling master:In this example, one i2c instance as slave and another i2c 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 slave is correct.

The i2c_read_accel_value example shows how to use I2C driver to communicate with an i2c device: 1. How to use the i2c driver to read a i2c device who_am_I register. 2. How to use the i2c driver to write/read the device registers.In this example, the values of three-axis accelerometer print to the serial terminal on PC throughthe virtual serial port on board.

The LED Blinky demo application provides a sanity check for the new SDK build environments and board bring up. The LED Blinky demo uses the systick interrupt to realize the function of timing delay. The example takes turns to shine the LED. The purpose of this demo is to provide a simple project for debugging and further development.

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.

The lpuart_functioncal_interrupt example shows how to use lpuart driver functionalAPI to receive data with interrupt method:In this example, one lpuart instance connect to PC, the board willsend back all characters that PC send to the board.
