CCS/MSP430G2553: float data transmission using UART in msp430g2553

I don't have v9, but in v8 it's in "Build Settings->Compiler->Advanced->Language->printf/scanf support".

Anticipating your next question: The last time I tried this the "full" support didn't fit on the G2553. ("nofloat" did, but that doesn't answer your question.) I suggest scaled-integer or maybe hex instead.

Unsolicited: As the founding (only) member of the "Stamp Out sprintf In Our Lifetimes Society", I suggest snprintf rather than sprintf.

[Edit: Fixed typo.]

In 9.2 under the project properties it is:

Build->ARM Compiler->Advanced Options->Language Options

If it is too big to fit into your project, you can adapt K&R's itoa example.

(Sorry about the sprintf() thing, how do you become a member?)
