Zeroplus Arduino starter kit with Logic Analyzer, Руководство пользователя

Страница: 108 / 123

In this experiment we are going to learn how to decipher an unknown
protocol. This procedure is called reverse engineering because we
look at the results to understand the logic behind the signals. A
logic analyzer is the perfect instrument for that type of tasks.
Here we are going to use a very common protocol called I2C. The
logic educator has a protocol decoder for I2C but for the sake of
the experiment we are going to pretend that it doesn’t.
When we reverse engineer a protocol, or a system, we see it as a
black box. There are inputs and outputs but what’s in between remains
unknown. Be it because the manufacturer didn’t provide a datasheet
for his product or because he wants to keep his technology secret.
In this experiment there are four buttons and each performs one
particular action.
