ftm_output_compare#
Overview#
The FTM project is a demonstration program of the SDK FTM driver’s output compare feature. It sets up one FTM channel to toggle the output when a match occurs with the channel value. The user should probe the FTM output with a oscilloscope to see the signal toggling.
Supported Boards#
FRDM-K22F
Hardware requirements
Mini/micro USB cable
FRDM-K22F board
Personal Computer
Oscilloscope
Board settings
This 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
Connect a USB cable between the PC host and the OpenSDA USB port on the board.
Open a serial terminal with these settings:
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 example.
Running the demo
These instructions are displayed/shown on the terminal window:
