The MRT project is a simple demonstration program of the SDK MRT driver. It sets up the MRThardware block to trigger a periodic interrupt after every 250 milliseconds. When the PIT interrupt is triggereda message a printed on the UART terminal and an LED is toggled on the board.

The OTP example project is a demonstration program that uses the KSDK software to access OTP ROM API.It just prints the version of API at the moment.

This example shows how to use SDK drivers to use the Pin interrupt & pattern match peripheral.

This example shows how to use SDK drivers to use the Pin interrupt & pattern match peripheral.

The power_manager_lpc application shows the usage of normal power mode control APIs for entering the three kinds of low power mode: Sleep mode, Deep Sleep mode and Sleep Power Down mode. When the application runs to each low power mode, the device would cut off the power for specific modules to save energy. The device can be also waken up by prepared wakeup source from external event. 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. - In order to meet typedef power consumption of DateSheet manual, Please configure MCU under the following conditions. 鈥?Configure all pins as GPIO with pull-up resistor disabled in the IOCON block. 鈥?Configure GPIO pins as outputs using the GPIO DIR register. 鈥?Write 1 to the GPIO CLR register to drive the outputs LOW. 鈥?All peripherals disabled.

The RIT project is a simple demonstration program of the SDK RIT driver. It sets up the RIThardware block to trigger a periodic interrupt at 1 second period interval to toggel a specifiedLED on board.

The RNG example project is a demonstration program that uses the KSDK software to generate random numbersand prints them to the terminal. 32 32-bit numbers are read and skipped per one 32-bit number read and used.This is to get a better entropy as suggested by user manual.

The example shows how to use USBD ROM stack to create and USB AUDIO class device. This device supports 2 channel audio in (MIC/LINE_IN) and 2 channel audio out (SPEAKERS/HEADPHONE).

The example shows how to use USBD ROM stack to create and USB AUDIO class device. This device supports 2 channels audio in.

The example shows how to use USBD ROM stack to create a virtual comm port. When the USB on J3 is connected to a PC, the host would recognize the USB connection as a new serial port.
