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 lpuart_edma Ring Buffer Example project is to demonstrate usage of the KSDK lpuart driver.

The lpuart_edma Example project is to demonstrate usage of the KSDK lpuart driver.In the example, you can send characters to the console back and they will be printed out onto console in a group of 8 characters.

The lpuart_hardware_flow_control Example project is to demonstrate usage of the hardware flow control function.This example will send data to itself(loopback), and hardware flow control will be enabled in the example.The CTS(clear-to-send) pin is for transmiter to check if receiver is ready, if the CTS pin is assert, transmiter startto send data. The RTS(request-to-send) is a pin for receiver to inform the transmiter if receiver is ready to receivedata. So, please connect RTS to CTS pin directly.

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

The lpuart_interrupt_ring_buffer Example project is to demonstrate usage of the KSDK lpuart driver.In the example, you can send characters to the console back and they will be printed out onto console in a group of 8 characters.

The lpuart_interrupt Example project is to demonstrate usage of the KSDK lpuart driver.In the example, you can send characters to the console back and they will be printed out onto console in a group of 8 characters.

The lpuart_polling Example project is to demonstrate usage of the KSDK lpuart driver.In the example, you can send characters to the console back and they will be printed out onto console instantly.

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_bple example shows how to use MCG driver to change from PEE mode to BLPE 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 -> BLPE Change back BLPE -> 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.
