34. Use the function file comparison and compare the last two
captures you’ve made.
35. See the result below.
There are several things to observe. First in position Read
(bottom) the frame is longer. Second, we remark a pattern
in the data. There are 4 pulses equally spaced. Therefore,
we can assume these four data correspond to the four digits
printed on the serial monitor.
After this brief analysis we already know that the protocol
I2C is composed of an address, a R/W segment and a block of
data. There are a few other parameters that make a full I2C
sequence. It would take a longer analysis to discover all
of them. To see the rest of the bits that make the command
