Support for Arduino Due

[fkromer]

The Arduino Due uses an Atmel SAM3X8E processor. Would be great to have support for this MCU class as well.

I'm available for beta testing btw ;-)

Have you tried to upload a client/server? I don't have any Due at the moment, so I can't test it. (but it compiles without errors, so it might work).

[fkromer]

Yes, I tried to upload the simple-server.ino via Programming (USB) Port.

In file included from C:\Users\Florian\Documents\Arduino\libraries\mWebSockets\src\base64\Base64.cpp:2:0:

Error compiling for board Arduino Due (Programming Port).

Ok, it's my bad, I checked Duemilanove, almost the same ;) In order to get it working, you need to go into platform.h and add another define #define PLATFORM_ARCHITECTURE_SAM 6 then do the following modification:

// ...
#elif defined(ARDUINO_ARCH_SAM)
#  define PLATFORM_ARCH PLATFORM_ARCHITECTURE_SAM
# else
// ...
#endif

Next head into base64/Base64.cpp and do a little update:

#if (PLATFORM_ARCH == PLATFORM_ARCHITECTURE_AVR) ||                            \
  (PLATFORM_ARCH == PLATFORM_ARCHITECTURE_SAMD21) || (PLATFORM_ARCH == PLATFORM_ARCHITECTURE_SAM)
// ...

Now it should compile.

@skaarj1989 No worries. In the simple-server.ino example I'm still getting some error.

That warning is negligible. It comes from the library.json/.properties pair. Does it run correctly?

[fkromer]

Sorry, had something different to do. simple-server.ino works just fine 🚀 Thanks
