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.

The FLASIAP project is a simple demonstration program of the SDK FLASIAP driver. It erases and programs a portion of on-chip flash memory. A message a printed on the UART terminal as various operations on flash memory are performed.

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).

The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The HelloWorld demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is toshow how to use the UART, and to provide a simple project for debugging and further development.

The IAP Flash project is a simple demonstration program of the SDK IAP driver. It erases and programs a portion of on-chip flash memory. A message a printed on the UART terminal as various operations on flash memory are performed.

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 multicore Low Power demo application demonstrates how to leverage the auxiliary core for periodicdata collection from sensors and passing the data to the primary core for further processing.The data from sensors is read with frequency of about 50Hz (every 20ms) by secondary core and storedinto a buffer. When the buffer contains 50 samples from sensors, the secondary core sends an interruptto the primary core to process the data. The primary core computes average values from temperature andpressure and then prints them with last values from other sensors to the console.The reading of data from sensors takes about 3ms, the rest of the time the cores are in deep sleepmode to reduce power consumption. In order to switch to deep sleep mode, the Power APIPOWER_EnterDeepSleep() is used and to wake it up the interrupt from uTick timer is used.When both cores can't go to the deep sleep mode (the primary core processes data or the secondary corereads data from the sensors), the core which has nothing to do goes to sleep mode by WFI. Also, whenthe primary core is switched to the sleep mode, the flash memory is powered down by Power APIPOWER_PowerDownFlash() and before waking up the primary core it is powered on by POWER_PowerUpFlash().The demo is based on:A. Fuks, "Sensor-hub sweet-spot analysis for ultra-low-power always-on operation," 2015 Symposium on VLSI Circuits (VLSI Circuits), Kyoto, 2015, pp. C154-C155.doi: 10.1109/VLSIC.2015.7231247URL: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=7231247&isnumber=7231231
