Overview
The CTimer Example project is to demonstrate usage of the KSDK ctimer driver. In this example, CTimer is used to generate a PWM signal.
SDK version
- Version: 2.15.000
Toolchain supported
- IAR embedded Workbench 9.40.1
- Keil MDK 5.38.1
- GCC ARM Embedded 12.2
- MCUXpresso 11.8.0
Hardware requirements
- Mini/micro USB cable
- LPCXpresso55s69 board
- Personal Computer
Board settings
No special settings are required.
Prepare the Demo
Note: MCUXpresso IDE project default debug console is semihost
- Connect a micro USB cable between the PC host and the CMSIS DAP USB port (P6) on the board
- Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):
- 115200 baud rate
- 8 data bits
- No parity
- One stop bit
- No flow control
- Download the program to the target board.
- Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
The log below shows example output of the CTimer simple PWM demo in the terminal window:
