Hello, how can I use the library to connect two serial ports?
I need to connect two Arduino.

Comment on Creating a Windows AIR Native Extension with Eclipse – Part 4 by quetwo

Thanks. I’ve been contemplating putting up a more comprehensive ANE training course about all these. You are right — if you need to use anything Windows GDI, WMI, .NET, etc. using MiniGW is a real pain in the rear. There is quite a bit of documentation from Adobe (including two recordings on Adobe TV) on how to build ANEs with Visual Studio. I always though it was crazy that they supposedly required VS in order to make them, which is where this video series came from. I just couldn’t afford VS, nor did I really want it on my machine here at home (I use it at work for some projects and really do like it — it just makes my machine noticeably slow).

Yeah, if you use C++, the namespace dictionary gets mangled unless you do the extern “C” in front of those functions. Unfortunately, it is not the same issue that people have been running across where the DLL fails to load and they get “method connect() not found” or something along those lines… That is an issue with Flash Builder, and the way it is passing the command-line strings to ADL.

Btw. I did too got: “The extension context does not have a method with the name xxx” message. But since I was using C++ for my example, I though this maybe has something to do with C/C++ specifics. However ones I added declarations for the functions into header file, i was able to call the functions just fine:

extern “C” __declspec(dllexport) void initializer(void** extData, FREContextInitializer* ctxInitializer, FREContextFinalizer* ctxFinalizer);
extern “C” __declspec(dllexport) void finalizer(void* extData);

extern “C” __declspec(dllexport) FREObject isSupported(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[]);
extern “C” __declspec(dllexport) FREObject getTextString(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[]);

This is awesome series of presentations about ANE. I’ve found it very educating and well made with lot of details which I’d personally spend tons of time to go over… So, thank you Nick!
Few points I’d like to mention:
1. Developing with MinGW has it’s own +/-. For the drawbacks I’d mention difficulty using standard Windows API. I’ve found this when tried using WMI classes and calls in C++ and MinGW obviously doesn’t support any of this, so…
2. I’d suggest for the Author to mention there is a “CDT Visual C++ Support” plugin for Eclipse which integrates Visual Studio (Express) into the CDT. It installs support for VS includes and Microsoft SDK (if it’s presented).
3. I found that developing an extension with C++ actually requires declaring your functions in extension’s Application.h header file. I think this is not the case if you use C. But with C++ I wasn’t able to call my functions if they are not declared in the header file.

Keep it up Nick!
Dmitry.

Sorry, I meant the socketData stops firing the event listener. Just to clarify.

Thanks! But no good.with 0022 either. It is able to read the analog input of a Force Sensitive Resistor for about a second on pin 0 but then it dies. If you think this is a valid issue, I can post to your google code instead of blowing up your blog post

I’ve had mixed results with the new Arduino 1.0 IDE and associated firmata. I do most of my testing with Arduino Studio 0022 when I’m using my older Duemilanove. http://arduino.cc/en/Main/Software

Seems like I’ve run into a road block. Seems the only version of firmata that will actually let me get data is SimpleAnalogFirmata. But it crashes after a few seconds. Can’t get any of the other ones in the examples that come with Arduino 1.0 to work. Is there a version you know of that will let me get Analog/Digital/IC2 data? If there is no real stable version, then is there an example project of ArduinoConnector code minus the as3glue? Thanks again for making an awesome library and all your help.

I’m using MinGW (set up properly in FB4.6 standalone IDE) + CDT as you prescribed.
