CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide range of supported microcontroller devices. The API connects microcontroller peripherals with middleware that implements for example communication stacks, file systems, or graphic user interfaces. More information and usage methord please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.The cmsis_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 Simple PWM Interrupt project is to demonstrate usage of the SDK CTimer driver as a PWM with interrupt callback functionsIn this example an IO pin connected to the LED is used as a PWM output line to generate a PWM signal.With an interrupt callback the PWM duty cycle is changed frequently in such a way that the LED brightness can be varied.

The DMA memory to memory example is a simple demonstration program that uses the SDK software.It executes one shot 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 and to provide a simple example fordebugging and further development.

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 demo explains how built in HWVAD( HW voice activity detector) in LPC5411x can be used towake up the device from sleep mode

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

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_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.
