The GPIO Example project is a demonstration program that uses the KSDK software to manipulate the general-purposeoutputs.The example is supported by the set, clear, and toggle write-only registers for each port output data register. The example take turns to shine the LED.

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

The fei_bpli example shows how to use MCG driver to change from FEI mode to BLPI mode: 1. How to use the mode functions for MCG mode switch. 2. How to use the frequency functions to get current MCG frequency. 3. Work flow Boot to FEI mode from default reset mode Change mode FEI -> FBI -> BLPI Change back BLPE -> FBI -> FEI Get System clock in FEI mode to blink LEDIn this example, because the debug console's clock frequency may change,so the example running information is not output from debug console. Here theLED blinks to show that the example finished successfully.

The pee_bpli example shows how to use MCG driver to change from PEE mode to BLPI mode: 1. How to use the mode functions for MCG mode switch. 2. How to use the frequency functions to get current MCG frequency. 3. Work flow Boot to PEE mode from default reset mode Change mode PEE -> PBE ->FBE -> FBI -> BLPI Change back BLPI -> FBI -> FBE -> PBE -> PEE Get System clock in PEE mode to blink LEDIn this example, because the debug console's clock frequency may change,so the example running information is not output from debug console. Here theLED blinks to show that the example finished successfully.

The pdb_adc16_trigger example shows how to use the PDB to generate a ADC trigger.Based on the basic counter, to use the ADC trigger, just to enable the ADC trigger's "milestone" and set the user-defined value for it.After the PDB counter is triggered to start, when the counter pass the "milestone", the ADC's Pre-Trigger would begenerated and sent to the ADC module.In this example, the ADC16 is configured with hardware trigger and conversion complete interrupt enabled.Once it gets the trigger from the PDB, the conversion goes, then the ISR would be executed.

The pdb_delay_interrupt example show how to use the PDB as a general programmable interrupt timer.The PDB is triggered by software, and other external triggers are generated from PDB in this project,so that user can see just a general counter is working with interrupt.

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.
