| Communication between LabView and CCS. |

Hey guys, I am trying to get a floating point number from labview to calculate power. However, my program in labview only accepts chars and strings. Here is my code in CCS so far:
| Code: |
void main()
{
float V, P;
while(TRUE)
{
delay_ms(1000);
V = 25;
char res[50];
float P = (V * V)/(getc());
ftoa(P, res, 1)
puts(res);
}
}
|
If I enter, for example, } for the resistor value I get the correct answer. But if I were to put 125 instead then I do not get the correct answer. Can anyone help me on this? Thanks! |

Basic C. Get a textbook!...
You need to read a sequence of characters, decode these to a number, and then do the maths.
gets, rather than getc, and then look at atof and it's other derivatives. |

I am new to C which is why I have trouble figuring this out haha |
