Assuming this setup is complete, you can confirm you are able to communicate with the hardware by running the example capture of traces given in the [[CW1173_ChipWhisperer-Lite]] quick-start.
<h2h4> Programming the Example </h2h4>
Note with the CW1173 you need to configure a clock before programming of the device will succeed. Programming of the target device will be done as part of the CW-Capture software setup, discussed next.
<h2h4> Communicating from CW-Capture Software </h2h4>
Next, open the CW-Capture software. Then perform the following steps:
[[File:cwsetup_scriptselection.png|600px889x889px]]
# Switch to the ''Python Console'' tab.
The window should change to indicate the connect succeeded:

To do so, simply scroll down and select the "setup_cwlite_xmega_aes.py" file:
[[File:cwsetup_scriptselection_xmegaconfig_cwliterun.png|400px]]
You'll nice the contents of the script contain the following setup[[File:cwsetup_scriptselection_xmegaconfig_cwliterun.png]]
TODO SCRIPTYou'll notice the contents of the script contain the following setup:<syntaxhighlight lang="python" line="1">scope.gain.gain = 45scope.adc.samples = 3000scope.adc.offset = 1250scope.adc.basic_mode = "rising_edge"scope.clock.clkgen_freq = 7370000scope.clock.adc_src = "clkgen_x4"scope.trigger.triggers = "tio4"scope.io.tio1 = "serial_rx"scope.io.tio2 = "serial_tx"scope.io.hs2 = "clkgen"</syntaxhighlight>This configuration block does the following (for lines 1 through 10): Line 1: Sets the input ADC gain Line 2: Sets the number of samples to record as 3000 samples long (this is normally used for the AES algorithm). Line 3: Sets an offset of 1250 samples from the trigger to when we start recording samples. Line 4: Sets the trigger as being a "rising edge" trigger. Line 5: Sets the internal clock generator to 7.37MHz Line 6: Sets the ADC as running at 4x that clock (so 29.48MHz) Line 7: Sets the trigger pin as GPIO4 (we previously set the trigger condition as rising edge, so this pin will be the one a rising edge is expected on). Line 8: Configures GPIO1 as the RX (Input). This is what the XMEGA target expects. Line 9: Configures GPIO2 as the TX (Output). This is what the XMEGA target expects. Line 10: Sets the "High-Speed 2" (HS2) pin as having the 7.37MHz clock output.

<li><p>Hit the ''Check Signature'' button and confirm the device is detected. If not you may have issues with the clock setup.</p>
<p>[[File:cw1173_xmegaprogb.png|image]]</p></li>
<li><p>Using the ''Find'' button, navigate to the <code>simpleserial-base-cw303.hex</code> which you built earlier with the <code>make</code> command. You can then press the ''Erase/Program/Verify'' button, and confirm the file is programmed into the XMEGA device:</p>
<p>[[File:cw1173_xmegaprogc.png|image]]</p>
<p>Note the programmer dialog not only shows the successful programming status, but also shows when the <code>.hex</code> file was last modified. Always confirm this matches with when you last remember compiling the program -- if it is widely different this suggests you have selected the wrong file!</p>
