MSP430FR2033: Error Message: error #19: extra text after expected end of number

Missing is where all of those symbols are defined.

The variables are global variables. 

Hi,

Could you also share the code about how you define these global variables?

Best regards,

Cash Hao

The global variables are at the top (outside the loop), and they are defined by "#define". Like this:

#define OUTPUT_MIN (666)
#define OUTPUT_MAX (399A)
#define PRESSURE_MIN_001BA (0)
#define PRESSURE_MAX_001BA (14.5038)
#define PRESSURE_MIN_400MD (-5.80151)
#define PRESSURE_MAX_400MD (5.80151)


P0 = i2cReadPressureHW001BA();

output_P0 = ((OUTPUT_MAX - OUTPUT_MIN)/(PRESSURE_MAX_001BA - PRESSURE_MIN_001BA))*(P0 - PRESSURE_MIN_001BA)+OUTPUT_MIN;
Press0 = 1.0 * (((P0 - OUTPUT_MIN)*(PRESSURE_MAX_001BA - PRESSURE_MIN_001BA))/(OUTPUT_MAX - OUTPUT_MIN)) + PRESSURE_MIN_001BA;
       

This is how my code is written 

OUTPUT_MAX is (399A)

It's in HEX. OUTPUT_MIN & OUPUT_MAX are in HEX. So 399A in decimal is 14,746 and 666 is 1638.

The real subtle one was the "666" number, since the compiler would silently accept it as a base10 number.

From Harbison and Steele:

These are the rules for determining the radix of an integer constant:

1. If the integer constant begins with the letters 0x or 0X then it is in hexadecimal notation...

2. Otherwise, if it begins with the digit 0, then it is in octal notation*.

3. Otherwise, it is in decimal notation.

*[This can really trip you up if you put a 0 in front of a number for formatting reasons]

I'll keep this in mind, but these rules make sense.
