When developing software in an embedded environment, the most likely
scenario when testing a new hardware interface is ... nothing happens. Unless
things work perfectly, it is difficult to know where to begin looking for problems.
With a logic analyzer, one can capture and visualize any data that is
being transmitted. For example, when working on software to drive a serial
port, it is possible to determine whether anything is being transmitted, and if
so, what. This becomes especially important where the embedded processor
is communicating with an external device (e.g. a Wii Nunchuk) – where every
command requires a transmitting and receiving a specific binary sequence. A
logic analyzer provides the key to observing the actual communication events
(if any !).
