The Visual Studio solution has configurations for 32 bit and 64 bit builds. You will likely need to switch the configuration to 64 bit and build that in order to get the analyzer to load in the Windows software. + +To test your analyzer, you will need to tell the Saleae Logic software where to load find your compiled analyzer dll. + +The four build combinations produce analyzer dll files in the following locations: +``` +.\Visual Studio\Win32\Debug\Analyzer.dll +.\Visual Studio\Win32\Release\Analyzer.dll +.\Visual Studio\x64\Debug\Analyzer.dll +.\Visual Studio\x64\Release\Analyzer.dll +``` + +Instructions to tell the Saleae Logic software where to find your new analyzer dll can be found here: +[How to set the developer directory in the Saleae software to use third party or user created analyzers.](http://support.saleae.com/hc/en-us/articles/208667506) + +Once you have set that directory and restarted the software, your new custom analyzer should appear in the list of analyzers you can add. + +## Debugging an Analyzer with Visual Studio + +Newer versions of the Saleae software cannot be used to debug custom analyzers. This means that older versions of the software and SDK must be used if you wish to attach a debugger and step through your code. + +*Note: it is impossible to attach a debugger to any version of the software that supports the new products. We are working on a solution to this problem, but for now that means you must rely on the simulation data generator for your analyzer to produce captures you can then debug in the older software.* + +To debug your custom analyzer, we recommend you use the 1.1.14 SDK with the 1.1.18 software. Because older versions of the software and SDK are 32 bit only, you will only be able to compile for 32 bit initially. Later, when you build the analyzer with the latest version of the SDK, you will be able to compile for 32 bit and 64 bit. + +The SampleAnalyzer repository and the AnalyzerSDK repository have been setup to make switching versions of the SDK easy. The SampleAnalyzer repository has a branch named "1.1.14-for-win32-debug". This branch and the master branch have exactly the same source code - the only difference is the project settings and the AnalyzerSDK submodule reference, which now points to the 1.1.14 AnalyzerSDK. + +Download the 32 bit stand-alone copy of the 1.1.18 software. The 32 bit standalone copy is required because the normal installer will not let you install the 32 bit software on a 64 bit operating system. + +Logic 1.1.18, 32 bit stand-alone: +http://downloads.saleae.com/betas/1.1.18/Logic1.1.18BetaWin32Standalone.zip + +This is also convenient because you will not need to uninstall the latest Saleae Logic software, or install this version. Simply unzip and run the 1.1.18 software. + +Please note - switching between Saleae Logic software versions has a tendency to reset the software's settings. This could cause the analyzer developer directory to get reset. If you no longer see your analyzer in the list, please verify that the analyzer developer directory is still set properly. + +To build and and debug your custom analyzer using the 1.1.14 sofware, follow these steps: + +- Switch to the "1.1.14-for-win32-debug" branch of the SampleAnalyzer repository. +- Using Visual Studio, open the solution file in the Visual Studio Folder. +- Switch the solution platform to from x64 to Win32. x64 is not able to build on this branch. +- Build the debug configuration. +- Launch the 1.1.18 32-bit Logic software. If the analyzer directory is not already configured, set that, and restart the software. +- The analyzer should now be visible in the list of analyzers you can add. +- In visual studio, open the Debug Menu, and select "Attach to process..." +- Locate Logic.exe in the list, select it, and click the Attach button. +- Add a break point on any line near the top of the WorkerThread() function, such as line 27, *mSampleRateHz = GetSampleRate();* +- In the Logic software, add your custom analyzer if you haven't already, and start a simulation. +- The breakpoint should hit. + + +**Updating to the latest SDK** + +Once you have finished debugging your analyzer using the "1.1.14-for-win32-debug" branch, we recommend committing your changes and then cherry-picking your commits to the master branch. Please do not simply merge changed into the master branch, as that may pick up other project settings not compatible with the latest SDK. + +In the future, we would like to simplify this even more, so branch switching is not required. + + +**Common issues on Windows** + +- The software says "Unable to 'LoadLibrary' on dll ... is not a valid Win32 application" + This is most likely because the analyzer was not built for the same platform architecture as the software running it. In almost all cases, this means the analyzer was compiled for 32 bit instead of 64 bit. Details to switch from 32 bit to 64 bit are included in the Analyzer SDK documentation on page 9. First, [add a x64 target to your project](https://msdn.microsoft.com/en-us/library/ms185328(v=vs.120).aspx). Then, edit the linker settings for the 64 bit configuration. Change the additional dependencies item from Analyzer.dll to Analyzer64.dll. + Note: Only the software versions 1.1.16 and later were built for 64 bit. Previous releases, including 1.1.15, were 32 bit only, which is why no 64 bit analyzer dll was provided. +- The Saleae software crashes on launch when the debugger is attached. + Versions after about 1.1.18 no longer allow debuggers to attach. In these cases, we recommend building with the 32 bit version of the 1.1.18 beta and the 1.1.14 SDK, and debug there. This restriction only applies to Windows. + +## Linux + +*Note: When using git clone, please remember to use --recursive to automatically also clone the AnalyzerSDK submodule* + +After you have cloned, forked, or downloaded the repository, and ran the rename_analyzer.py script, there are two additional steps required to run the analyzer. + +First, if you are using Linux 64 bit, you need to delete the 32 bit libAnalyzer.so file, and rename the libAnalyzer64.so file to just libAnalyzer.so. + +``` +mv AnalyzerSDK/lib/libAnalyzer64.so AnalyzerSDK/lib/libAnalyzer.so +``` + +Then run build_analyzer.py + +``` +python build_analyzer.py +``` + +That's it! To debug the analyzer, you need to first tell the Saleae Logic software where to find your newly compiled *.so file. + +[How to set the developer directory in the Saleae software to use third party or user created analyzers.](http://support.saleae.com/hc/en-us/articles/208667506) + +The two variants of the newly compiled analyzer can be found here: + +``` +debug/libAnalyzer.so +release/libAnalyzer.so +``` + +### Debugging with GDB on Linux + +To debug your analyzer, you will need to attach gdb to the Logic application, something like this: +``` +gdb /Home/YourUserName/Desktop/Logic 1.2.14 (64-bit)/Logic +``` +And then test setting a breakpoint like this: +``` +break MyAnalyzer::WorkerThread +``` +Because your analyzer hasn't been loaded yet, GDB will notify you that it can't find this function, and ask if you want to automatically set this breakpoint if a library with a matching function is loaded in the future. Type y + +Then type run to start the application. Add your custom analyzer and start a simulation. This will trigger the breakpoint. + +## MacOS + +### Build Script Based Project + +*Note: When using git clone, please remember to use --recursive to automatically also clone the AnalyzerSDK submodule* + +After you have cloned, forked, or downloaded the repository, and ran the rename_analyzer.py script, there is one additional step required to run the analyzer. + +run build_analyzer.py + +``` +python build_analyzer.py +``` + +That's it!

Click the "+" button on the analyzers panel, and then select your analyzer. In this case, the user facing name of the analyzer was set by the Python script to "Xcode Analyzer". Yours may be different. +- If your analyzer is missing, it could indicate that the dylib was not created, or that the developer path was not set properly. Please review the previous steps for any possible errors. +- The settings dialog for your custom analyzer will appear. Click "Save". + +![19](./images/19_-_logic_software_add_analyzer_menu.png) + +- Here is your fresh new analyzer, now added to the software. Note that our breakpoint hasn't fired yet. If you had captured data previously, it might fire now, since analyzers will automatically start processing if they are added to an existing analyzer. + +![20](./images/20_-_analyzer_in_Logic.png) + +- Press start to start a simulation. +- Since your analyzer has already been added, the simulator will call your simulation data generator code. The analyzer also starts processing the moment data has been captured, so your breakpoint should fire immediately. + +![21](./images/21_-_logic_software_start_button.png) + +- Here you can see that the debugger was attached and your break point has been hit. You can examine variables, set new break points, or press continue from the debug menu at the bottom. + +![22](./images/22_-_breakpoint_hit.png) + +- Congratulations!
