Overview
========
The FTM pwm tow channgel Example project is a demonstration program that uses the KSDK software to generate a square
pulse PWM on 2 channel to control the LED brightness.
- FTM generates a PWM with the increasing and decreasing duty cycle.
- LED brightness is increasing and then dimming. This is a continuous process.
Toolchain supported
===================
- IAR embedded Workbench 7.50.1
- Keil MDK 5.17
- GCC ARM Embedded 2015-4.9-q3
- Kinetis Development Studio IDE 3.0.0
- Atollic TrueSTUDIO 5.4.0
Hardware requirements
=====================
- Mini/micro USB cable
- FRDM-K22F board
- Personal Computer
Board settings
==============
This MPU Example project does not call for any special hardware configurations.
Although not required, the recommendation is to leave the development board's jumper settings
and configurations in default state when running this example.
Prepare the Demo
================
1. Connect a USB cable between the PC host and the OpenSDA USB port on the board.
2. Open a serial terminal with these settings:
- 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 example.
Running the demo
================
These instructions are displayed/shown on the terminal window:
~~~~~~~~~~~~~~~~~~~~~~~
FTM example to output PWM on 2 channels
You will see a change in LED brightness if an LED is connected to the FTM pin
If no LED is connected to the FTM pin, then probe the signal using an oscilloscope
