The FTM project is a demonstration program of the SDK FTM driver's output compare feature.It sets up one FTM channel to toggle the output when a match occurs with the channel value. The usershould probe the FTM output with a oscilloscope to see the signal toggling.

The FTM pwm two channel Example project is a demonstration program that uses the KSDK software to generate a square pulse PWM on 2 channel to control the LED brightness.- FTM generates a PWM with the increasing and decreasing duty cycle.- LED brightness is increasing and then dimming. This is a continuous process.

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 sai_interrupt_transfer example shows how to use sai driver with interrupt:In this example, one sai instance playbacks the audio data stored in flash/SRAM using interrupt.

The uart_polling example shows how to use uart driver in polling way:In this example, one uart instance connect to PC through uart, the board will send back all characters that PCsend to the board.

In this example, the adc16 module is initiealized and used to measure the VREF output voltage. So, it cannot use interal VREF as the reference voltage. Then, user should configure the VREF output pin as the ADC16's sample input. When running the project, it will firstly measure the VREF output voltage within the default (factory) trim value. Then, it will measure the VREF output voltage under different trim value.
