my project handover timeline is the day after tomorrow plz hlp
this is a library i ve modified and that error comes up even if i comment the line or even the whole code .compiler seems to be stuck on it . thx in advance

You know, I don't understand why but if I change the name of the parameter, it works...

  void setSPR1(float SPR1a);

nope doesn`t work sorry

"SPR1" is a macro, and has the value 1.
It doesn't make any sense to write void setSPR1(float 1);

Please use code tags.

Cool, I wondered what it was. I looked for that kind of thing, but didn't see it anywhere.

OP - What you posted here is a "header" not a code file. I assumed that you have the rest of the code somewhere else? You might want to post everything if it's still not working. We can't really go farther than "validating" the file you posted - it doesn't produce any code, it's just definitions.
