Detailed Description

rusEfi console wave sniffer logic

Here we have our own build-in logic analyzer. The data we aggregate here is sent to the java UI rusEfi Console so that it can be displayed nicely in the Sniffer tab.

Both external events (see logic_analyzer.cpp) and internal (see signal executors) are supported
