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

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:
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....
Best Wishes |
