Overview
|
|
========
|
|
This SCTIMer project is a demonstration program of the SDK SCTimer driver's PWM generation. It sets up a PWM signal
|
|
and periodically updates the PWM signals dutycycle.
|
|
|
|
Toolchain supported
|
|
===================
|
|
- IAR embedded Workbench 8.32.3
|
|
- Keil MDK 5.27
|
|
- MCUXpresso 11.0.0
|
|
- GCC ARM Embedded 8.2.1
|
|
|
|
Hardware requirements
|
|
=====================
|
|
- Mini/micro USB cable
|
|
- LPCLPCXpresso54102 board
|
|
- Personal Computer
|
|
|
|
Board settings
|
|
==============
|
|
No special settings are required.
|
|
|
|
Prepare the Demo
|
|
================
|
|
1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J6) on the board
|
|
2. 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
|
|
3. Download the program to the target board.
|
|
4. 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 SCTimer driver PWM demo in the terminal window:
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
SCTimer example to output center-aligned PWM signal
|
|
|
|
You will see a change in LED brightness if an LED is connected to the SCTimer output pin
|
|
If no LED is connected to the pin, then probe the signal using an oscilloscope
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
- Probe oscilloscope at J2-18 to see output signal.
