Sprintf error 114
PostPosted: Thu Jan 26, 2012 11:32 am     Reply with quote
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

Code:



#include <PIATTAFORMA.h>
#ifndef DWORD
#define DWORD int32
#endif

#ifndef WORD
#define WORD int16
#endif

DWORD get_fattime(void)
{
   return 0;
}

#include <ff.h>


int16 data=85;
int16 value=0;
//int8 databyte1=0;
//int8 databyte0=0;
//int8 TIME_H=0,TIME_L=0, CKS=0;



char mesg[32];


#define RxADCQsize 32
volatile int16   RxBaseADC[RxADCQsize];

// Rx Ring Buffer control
volatile BYTE   RxHeadADC;
BYTE   RxTailADC;

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.
