[Flightgear-devel] Serial Connection is broken in Windows binary
Hi everybody, I'm getting results with Arduino and FGFS, at least in a Linux environment, that's good. But I will just shortly mention there's something broken in the Windows binaries. I have a fully working hardware/software system that let's me feed FGFS with data coming from a serial connected Arduino board, it runs smoothly on Linux but doesn't on Windows. I'm running FGFS 2.0 on Windows7, with very similar command line options; FGFS correctly reads it's own new handmade protocol (doesn't complain and creates a new property in the tree that I use for checking things), but it does ignore what's coming in. Fact is the serial connection is correctly sending data, I can check it with Arduino's own serial monitor and with a Python script too. It's just FGFS not updateing its property tree :-( I don't know what can be wrong in FGFS's code, I don't even know if there's something I do wrong (but I don't think so); at least I wanted to report that on this ML. Maybe someone cares and/or wants to know more, and maybe someone has a few hints on what I should look for (just in case it's only because of me).

One common source of trouble when moving between Windows and Linux (or Mac) are line feed issues. Maybe the fgfs parser is confused by the encoding it gets from your port/driver. Windows uses CR LF (\r\n) as a line feed, Linux/Mac uses LF only (\n). A serial port can be configured to convert the line feed encoding, i.e. Linux may convert CR LF to LF, a Windows driver may do the opposite. I remember configuring (disabling) this auto-conversion property for a serial port years ago - when I used python for an RS232 interface on Windows and Linux. fgfs probably expects \n only - even when running on Windows. Just an idea. Other than that: I have no idea... ;-) cheers, Thorsten -- What You Don't Know About Data Connectivity CAN Hurt You This paper provides an overview of data connectivity, details its effect on application quality, and explores various alternative solutions. http://p.sf.net/sfu/progress-d2d ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
Re: [Flightgear-devel] Serial Connection is broken in Windows binary
There is an entirely different code path/implementation for serial IO under windows versus Linux, so it's entirely possible that a problem has crept in for Windows. I don't have a good way to test it here though. Curt.
