3. Examples provided

There are 5 demonstration examples provided with the development kit documentation pack:

1. aes_demo

2. fcast_demo

3. fstep_demo

4. tone_demo

5. keyfob_demo

6. rke_demo

All are precompiled and ready to be used without compilation for convenience. The user just needs to go to the

<name>_demo/bin

directory and open the Silicon Labs IDE *.wsp project file by the Silicon Labs IDE.

Each demo can be built and debugged from within the Silicon Labs IDE.

3.1. AES demo-aes_demo

AES example with timer usage example. The timer counts the number of system clock cycles needed to run

encryption, decryption key preparation, and decryption.

3.2. Frequency casting demo-fcast_demo

This example shows the main flow when using the main vFCast_Tune tuning function. It also shows how to

transmit a predefined data packet when a button is pressed. The buttons are not debounced in this simple

example.

3.3. Frequency casting two step demo-fstep_demo

This example shows the main flow when the user wants to switch in between several frequencies fast. It is possible

to call vFCast_Tune()for several frequencies in advance, collect the information calculated, and then just quickly

apply it during transmission. This is for the cases when the 5-6 ms time spent in vFCast_Tune() is prohibitive for

switching in between frequencies.

3.4. Tone (CW) generation demo-tone_demo

This example shows the steps to generate continuous wave (tone) at a desired frequency. There are two main files

compiled to two separate example applications:

tone_demo

Run main tune vFCast_Tune once, then use only fine tuning to track the temperature changes.

tone_demo_ptune

Periodic tuning, run main tune vFCast_Tune every minute and use the fine tuning only in between the main tuning

events. However, there will be about 6 ms interruption of the output during the main tuning, once per minute.

The Keil µVision project tone_demo.Uv2 covers both targets:

tone_demo

tone_demo_ptune

For the Silicon Labs IDE there is only one target per *.wsp file, so there

are two project files:

tone_demo.wsp

tone_demo_ptune.wsp
