The DMA wrap transfer example is a simple demonstration program that uses the SDK software.It executes a wrap transfer from source buffer to destination buffer using the SDK DMA drivers.The purpose of this example is to show how to use the DMA wrap feature.

This example shows how to use DMA to transfer data from DMIC to memory.

Demonstrates the DMIC working with I2S. Audio is converted to samples in the DMIC module.Then, the data is placed memory buffer. Last, it is send data to the I2S buffer and send to the CODEC, then the audio data will be output to Lineout of CODEC.~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The emc_sdram example shows how to access the SDRAM.In this example, user shall initialize the EMC (external memory controller), initialize theEMC dynamic memory controller before access the external SDRAM.If the sdram example fails, please make sure to check the following points:1. Please take refer to the board.readme to check the jumper settings on your board.2. Please take refer to the EMC chapter in API RM to do the delay calibration to found the best delay for your board, then update the delay to the EMC clock delay control registers in the system configure module registers.

The enet_rxtx_rxinterrupt example shows the simplest way to use ENET functional tx/rx API for simple frame receive and transmit.1. This example shows how to initialize the ENET.2. How to use ENET to receive frame in polling and to transmit frame.The example transmits 20 number broadcast frame, print the number and the mac address of the recieved frames.

The enet_rxtx_rxinterrupt example shows the simplest way to use ENET transactional tx/rx API for simple frame receive and transmit.1. This example shows how to initialize the ENET.2. How to use ENET to receive frame in interrupt irq handler and to transmit frame.The example transmits 20 number broadcast frame, print the number of recieved frames. To avoidthe receive number overflow, the transmit/receive loop with automatically break when 20 numberare received.

The enet_rxtx_rxinterrupt example shows the simplest way to use ENET transactional tx/rx API for simple frame receive and transmit.1. This example shows how to initialize the ENET.2. How to use ENET to receive frame in polling and to transmit frame.The example transmits 20 number broadcast frame, print the number and the mac address of the recieved frames.

This example shows how to use SDK drivers to use the Frequency Measure feature of SYSCON module on LPC devices.It shows how to measure a target frequency using a (faster) reference frequency. The example uses the internal main clock as the reference frequency to measure the frequencies of the RTC, watchdog oscillator, and internal RC oscillator.

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).
