HI there, I'm working in a logger system that send logged data to a PC. By now I'm developing the PC Software in C# with a lot of very usefull tools that allow me to change from Hexa to Float, Flota to Hexa, to String... what I want, but I know when I want to develope in Visual4Android I will not be so lucky.

So, someone knows how can I convert ASCII data string (4 bytes received by serial SPI) in to a float data? In other words the opposite of sprintf.

Mi idea is send a float data converted by sprinf in ASCII string and reseive float configuration data also in ASCII strings.

I'm using the MCF51CN128 ColdFire.


Thank you for your time!
