This example shows how to use SDK drivers to use the Group GPIO input interrupt peripheral.

The GPIO Example project is a demonstration program that uses the KSDK software to manipulate the general-purposeoutputs. The example use LEDs and buttons to demonstrates GPIO API for port and pin manipulation (init, set,clear, and toggle).

The HelloWorld demo prints the "Hello World" string to the terminal using the SDK UART drivers and repeat what user input. The purpose of this demo is to show how to use the UART, and to provide a simple project for debugging and further development.

The i2c_dma_b2b_transfer_master example shows how to use i2c driver as master to do board to board transfer with DMA: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_dma_b2b_transfer_slave example shows how to use i2c driver as slave to do board to board transfer with a DMA 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_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_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 I2S example project uses one I2S interface to continuously record input sound to a bufferand another I2S interface to playback the buffer to output - digital loopback.It requires NXP Mic/Audio/Oled Shield with WM8904 codec.It needs to have 1-2 connected on JP3.
