Problem with using FastSerial.h and Wire.h

system · November 11, 2013, 3:45pm

Hello all,

i have a problem which i can't actually understand.
I'm trying to read the mavlink message from the PX4Flow sensor (this works fine) and send it via i2c to another main controller board. The code are attached.
But if i include the Wire.h in the code where also FastSerial.h is included, without doing any call to Wire.h .
Than the arduio board seems to be frozen.
As far i understand it seems that the Wire.h aren't compatible with the FastSerial.h!
Does anyone know the issue for that or have any idea to get it working?

Thanks a lot

do you have a link to fastSerial.h? documentation?

I can't find nothing useful besides this link to the library:

I don't know really what this library does, but as i understood the handle the sending data as a background program. So it doesn't block the whole system by sending/receiving data over the serial port.
