Sprintf error 114 |
Posted: Thu Jan 26, 2012 11:32 am |

Hello, i am using a command
sprintf(pressure,"Valore=%d\r\n",RxBaseADC[RxTailADC++]);
where the RxBaseADC[RxTailADC++] is a int16[32]
but when i try to compile it gives me this error:
error 114: sprintf format type is invalid
here is my full code
in particular the RxBaseADC[RxTailADC++] variable is coming from a ring buffer that i implement in the code
has anyone any suggestion? i don't know why this error is coming
thank you all

hmmmmmmmm.....
sprintf(pressure,"Valore=%d\r\n",RxBaseADC[RxTailADC++]);
My guess is that the compiler doesn't like the ++ added to the end of the varibale RxTailADC.
I'd suggest trying something like..
dummy_value=1;
sprintf(pressure,"Valore=%d\r\n",RxBaseADC[dummy_value]);
and see what happens.
If the error goes away then you've found out why there is the problem |

i have changed my code in this way:
Int16 dummy_value;
dummy_value=RxBaseADC[RxTailADC];
RxTailADC=(RxTailADC+1);
sprintf(pressure,"%d",dummy_value);
but the error keeps going!!!!!!!! |

%d specifies a signed integer ( 8 bits) -128 to +127
dummy_value has been declared a long integer(16 bits)
if you press F11 with your project open, you''ll access the onscreen Help files that CCS provides.. |

temtronic makes a good point here. Lets hope the F11 help key isn't missing on some keyboards. Also a quick look at a beginners C code tutorial especially basic syntax might also be a useful strategy for some. Chances are if you are new to CCS then the error you have has already been made before so searching C syntax and this board often will lead to a faster solution. |
