mBed port

[idea--list]

Hi there,
I ported this library to mBed and am ready to share that.
My question is: would you prefer keeping separate versions for Arduino and mBed or shall merge them together by using preprocessor rules?

Happy to merge it here if you'd like.

Seems i was telling too early.
If i run the original Arduino code on the same board then the GPS module begins to communicate via I2C, interestigly if i run my ported mbed version now I2CGPS::begin returns true and the mbed port can advance to I2C::check, I2C::availaible and I2CGPS::read methods which seem to work right.

However if i cut power and restart the board, i can not fetch any data as the mbed version of I2CGPS::begin fails to do its job. I already reviewed my code but i can not find the root of this bug, so i can not apply a fix.

Update: it seems i could resolve the issue. Problem was that the GPIO pins of my board behave somewhat different in Arduino than in mBed. As of now the current is constant on all the pins and the ported version of I2CGPS::begin works as expected.

This however shows that mbed is far more complex and will need more thorough testing before i can commit my code.

@nseidle
Just made PR #6 , please review and try it if that works as expected as i could test it only on 1 target.
