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.

The Power manager demo application demonstrates the use of power modes in the KSDK. The demo use the notification mechanismand prints the power mode menu through the debug console, where the user can set the MCU to a specific power mode. The usercan also set the wakeup source by following the debug console prompts. The purpose of this demo is to demonstrate theimplementation of a power mode manager. The callback can be registered to the framework. If a power mode transition happens,the callback will be called and user can do something. Tips: This demo is to show how the various power mode can switch to each other. However, in actual low power use case, to save energy and reduce the consumption even more, many things can be done including: - Disable the clock for unnecessary module during low power mode. That means, programmer can disable the clocks before entering the low power mode and re-enable them after exiting the low power mode when necessary. - Disable the function for unnecessary part of a module when other part would keep working in low power mode. At the most time, more powerful function means more power consumption. For example, disable the digital function for the unnecessary pin mux, and so on. - Set the proper pin state (direction and logic level) according to the actual application hardware. Otherwise, the pin cirrent would be activied unexpectedly waste some energy. - Other low power consideration based on the actual application hardware.

The Power mode switch demo application demonstrates the use of power modes in the KSDK. The demo prints the power mode menuthrough the debug console, where the user can set the MCU to a specific power mode. The user can also set the wakeupsource by following the debug console prompts. The purpose of this demo is to show how to switch between different power modes, and how to configure a wakeup source and wakeup the MCU from low power modes.

The PWM project is a simple demonstration program of the SDK PWM driver.The pulse width modulator (PWM) module contains PWM submodules, each of which is set up to control a single half-bridge power stage.Fault channel support is provided. This PWM module can generate various switching patterns, including highly sophisticated waveforms.It can be used to control all known Switched Mode Power Supplies (SMPS) topologies.

This demo application demonstrates the EflexPWM fault demo.This application demonstrates the pulse with modulation function of EflexPWM module. It outputs thePWM to control the intensity of the LED. PWM shut down when a fault signal is detected on the CMPoutput. One input of CMP, other input is from internal DAC.

The Shell Demo application demonstrates to control Leds by commands.

The Thermistor Lab Demo application demonstrates how to use PDB to trigger ADC and measure on-board thermistor.This demo shows how to configure and use the ADC module to sample the differential voltage across onboard thermistors RT1-RT4.If the user touches any on-board thermistor with a finger, the lab application detects a change in the thermistor temperatureand starts flashing the corresponding LED pair.

The uart_edma ring buffer example shows how to use uart driver with EDMA:In this example, one uart instance connect to PC through uart, the board willsend back all characters that PC send to the board.

The uart_edma example shows how to use uart driver with EDMA:In this example, one uart instance connect to PC through uart, the board willsend back all characters that PC send to the board.Note: The example echo every 8 characters, so input 8 characters every time.

The uart_functioncal_interrupt example shows how to use uart driver functionalAPI to receive data with interrupt method:In this example, one uart instance connect to PC through uart, the board willsend back all characters that PC send to the board.
