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.

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 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 us USBD ROM stack to creates a generic HID device. The example supports 1 byte report and loops back the data received in SET_REPORT message..

The SCTimer project is a simple demonstration program of the SDK SCTimer's driver capabiltiy to generate PWM signals.

The Shell Demo application demonstrates to control Leds by commands.

The spi_half_duplex_dma transfer_slave example shows how to receive and transmit data to master board.Notice: The SPI slave of this example uses dma mode. The data transfer size(not buffer size) is twice ofthe master's transfer size. The first half of the transmission will receive data, and the second half will senddata back to master, so the address of the receive buffer is &rxDataPolling[64].In this example, one spi instance as slave and another spi instance on the other board as master. Master sends a piece of data to slave, and receive a piece of data from slave. This example checks if the data received from master is correct. And slave will print what it received.

The spi_interrupt_board2board_slave example shows how to use spi driver as slave to do board to board transfer with interrupt:In this example, one spi instance as slave and another spi instance on other board as master. Master sends a piece ofdata to slave, and receive a piece of data from slave. This example checks if the data received from master is correct.

The touch_cursor demo shows how to use LCD hardware cursor and position it using touch panel.In this example, a 32x32 cursor is shown. The cursor's position is changed in reaction to detected touch.

The usart_dma example shows how to use usart driver with DMA:In this example, one usart instance connect to PC through usart, 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.
