This analyzer decodes Apple Desktop Bus traffic.
It may be connected directly to the ADB pin of any Apple Desktop Bus network.
It will decode the command and data transactions on the bus.
Attention / sync or start bits will be marked with a green blob. Stop bits will be marked with a red square. Service requests during stop bits will be marked with an upward arrow.
An example capture may be generated to demo the behaviors described above.
Dependencies:
- XCode with command line tools
- CMake 3.13+
Installing command line tools after XCode is installed:
xcode-select --install
Then open XCode, open Preferences from the main menu, go to locations, and select the only option under 'Command line tools'.
Installing CMake on MacOS:
- Download the binary distribution for MacOS,
cmake-*-Darwin-x86_64.dmg - Install the usual way by dragging into applications.
- Open a terminal and run the following:
/Applications/CMake.app/Contents/bin/cmake-gui --install
Note: Errors may occur if older versions of CMake are installed.
Building the analyzer:
mkdir build
cd build
cmake ..
cmake --build .
Dependencies:
