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 IRQ Example project is a demonstration program that uses the MCUXpresso SDK software to useIRQ pin interrupt.The example uses the IRQ pin to generate a falling edge interrupt to show the example.

The KBI Example project is a demonstration program that uses the KSDK software to usekeyboard interrupt.The example uses one KBI pin to generate a raising edge interrupt to show the example.

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 pflash example shows how to use flash driver to operate program flash:

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

The PWT project is a simple demonstration program of the SDK PWT driver. It sets up the PWThardware block to edge detection, capture control part and detects measurement trigger edges andcontrols when and which pulse width register(s) will be updated. Once the input signal is received,this example will print overflow, positive pulse width and negative pulse width.
