This plugin is for use in the Saleae Logic program to decode captured data from Realtek's TX2/RX2 chip pair, used in RC cars.
To build the plugin, change to the plugin directory and run python build_analyzer.py. The build_analyzer file has been modified from the provided build script from Saleae to accommodate an error building on 64-bit OS X. This plugin should build cross-platform, depending on python version.
Once built (look for any errors in the build output), open Saleae Logic and Click
Options > Preferences > "Developer" Tab
The only option should be an area to specify a folder. Point this to the release folder in this plugin directory. If you already have a generic user-directory to collect plugins, copy release/libTRX2Analyzer.dylib to your folder. Other architectures may use other file extensions (Mac: dylib; Linux: so; Windows: dll).
After capturing data from The TX2's SO pin, or the receiving circuit / input on the RX2 (or simulating data), add the analyzer "Realtek T/RX2" and specify the channel used to capture this data. Also specify whether or not you are capturing transmitted or received data (TX2 or RX2 respectively).
The plugin will then place a green "start" marker at the start of every header. A data bubble is placed above the command portion of the packet with the command number sent.
This software is not yet robust against packet errors, artifacts from button bouncing, different clock rates and more. It is, at best, beta-quality. It is provided as-is, with no guarantee of it's accuracy.
