<h2> What is SimpleSerial </h2>
[[SimpleSerial]] is the communications protocol used for almost all of the ChipWhisperer demo project. It's a very basic serial protocol which can be easily implemented on most systems. This system communicates using a standard asyncronous asynchronous serial protocol, 38400 baud, 8-N-1.
All messages are sent in ASCII-text, and are normally terminated with a line-feed ('\n'). This allows you to interact with the simpleserial system over a standard terminal emulator.
: This is the response from the system. If data has been encrypted with a 'p' for example, the system will respond with the 'r' sequence automatically. So sending the earlier example means the result of the encryption was <code>cbbd4a2b34f2571758ff6a797e09859d</code>.
<h2> Building the Basic Example </h2>For this example, we'll be working off of <code>simpleserial-base</code> firmware, which by default just echos the 16 bytes we send to the target back to us.{{CollapsibleSection

Note that if you've closed ChipWhisperer Capture since programming the device, you'll need to rerun the connect_cwlite_simpleserial.py and target setup scripts:# Open the status monitor under <i>Tools > Encryption Status Monitor</i>.# Resize the monitor window. The monitor will show sent & received data to the target.# Hit the ''Run 1'' button ([[File:Capture One Button.PNG|image|link=http://wiki.newae.com/File:Capture_One_Button.PNG]]). You may have to hit it a few times, as the very first serial data is often lost. You should see data populate in the ''Text Out'' field of the monitor window. Note that each byte of the ''Text In'' is incremented in the ''Text Out'' field.
