100 Errors need 1 solution
PostPosted: Sun Aug 24, 2008 7:36 am     Reply with quote

Hi after running my calibration routine for my accelerometer i get 100 errors Sad

Errors are constant clearly I'm doing something wrong

And the code for this mess is
Code:
void Calibrated_output(void);

{
//From ADC GET DATA
   
//X1 = Y1 = Z1 = +G values
//X2 = Y2 = Z2 = 0G values
//X3 = Y3 = Z3 = -G values

//From CAL CONSTANT

//MA_X = X1 / X2 ;
//MB_X = X2 / X3 ;
//MA_Y = Y1 / Y2 ;
//MB_Y = Y2 / Y3 ;
//MA_Z = Z1 / Z2 ;
//MB_Z = Z2 / Z3 ;

      Measure_Xout();  // Get converted reading from adc                   
      Measure_Yout();  // Get converted reading from adc
      Measure_Zout();  // Get converted reading from adc
            
    VinX  = ((float)Xaxis * ((3.3/(2*X2raw))));   //Adc values get multiplies by scaling factor"(3.3v/2*X2raw))
    VinY  = ((float)Yaxis * ((3.3/(2*Y2raw))));   //Adc values get multiplies by scaling factor"(3.3v/2*Y2raw))
    VinZ  = ((float)Zaxis * ((3.3/(2*Z2raw))));   //Adc values get multiplies by scaling factor"(3.3v/2*Z2raw))
         

   if(VinX > X2)
   {
          Calibrate_Output = ((VinX  - X2 ) * MA_X ) + 1.65;
   
   }else if( VinX == X2 )
   {
          Calibrate_Output = 0.0; //X2 which equates to 0g's ;
   
   }else if( VinX < X2 )
   {
          Calibrate_Output = X2 - ((VinX - X2 ) * MB_X );
   }
     
         printf("Xcal %3.2f\n\r" ,Calibrate_Output);
       
         Calibrate_Output = 0;

   //For the case of Y             


   If( VinY > Y2 )
   {
          Calibrate_Output = (( VinY - Y2 ) * MA_Y ) + 1.65;
   
   }else if( VinY == Y2)
   {
          Calibrate_Output =  0.0; //Y2 which equates to 0g's 

   }else if( VinY < Y2 )
   {
          Calibrate_Output = 1.64 - ((VinY - 1.64 ) * MB_Y );
   }
 
          printf("Ycal %3.2f\n\r" ,Calibrate_Output);
........
..
.
.

The difficult part for me is I'm not in the software or programming side of engineering. I'm a instrumentation student at varsity but I like to try and program but don't get much time though. I'm hope the problem above is not too big.

Kind Regards.

Your first declaration, is terminated with a semicolon. This 'ends' the declaration. You then have a large block of code, with no name, which is not part of the declaration...

As extra info to Ttelmah's answer:
Code:
void Calibrated_output(void);
This line is seen by the compiler as a 'function declaration', the definition of a function name. You meant a 'function implementation', the actual function code. The difference between the two is the ';' at the end of the line...

Good day all,
Can someone help me on those error. Me too are like jacqueskleynhans, who are right now trying to learn c programming. Really hope someone can help me.

Code:

for(i=0; i<8> 0) output_float(sht_data_pin);  //data high if MSB high
   else output_bit(sht_data_pin, 0);                    //data low if MSB low


Makes no sense. else is part of an if statement NOT a for. You also end the for with } but do not have the corrosponding openeing { after the for.

Your for statement is wrong as well!

Simply start with the first error message and check the syntax, apparently something is wrong here:
Code:
for(i=0; i<8> 0)

You also have non-matching parantheses and similar basic issues.

Start with the sht75 driver. Note that _with it_, there is a 'main'. You need to have the driver in an include file (sht75.c), and the main (perhaps main.c), and then compile the latter. This then loads the driver.
The posted code compiles _without error_.

The line in the original code, bears little resemblance to the line in the code you have posted:

Yours:
Code:

for(i=0; i<8> 0) output_float(sht_data_pin);  //data high if MSB high
   else output_bit(sht_data_pin, 0);                    //data low if MSB low


Original:
Code:

 for(i=0; i<8; i++)
  {
   output_bit(sht_clk_pin, 0);                          //clk low
   if((iobyte & mask) > 0) output_float(sht_data_pin);  //data high if MSB high
   else output_bit(sht_data_pin, 0);                    //data low if MSB low


Use 'cut and paste', rather than retyping. If retyping, _read_ and try to understand what you are typing.....

The errors are in your typing....
