C compilation errors: deviation of '\ 200' in the program and expected ')' before the numeric constant

I copied this program and I am having problems with the void downFrequency function (I think). This is for Arduino Uno. Here are the compiler errors: Compiling 'MY_dds' for 'Arduino Uno'

In downFrequency you somehow ended up with "en dash" characters, not the usual minus signs.

Make sure you are editing a text editor, not a text editor; and for each of them:

 toFrequency = (toFrequency – 1); ^

delete the marked character and enter a minus sign as a normal character.

(If you're interested in the gory details, the Unicode 2013 dash character encoded in UTF-8 as three bytes with octal values ​​of 324,2200,223, so you see these numbers in error messages.)

The compiler complains that there are non-ASCII characters in the source file.

My octal fu is rusty, but to me it looks like UTF-8. 342 200 223 - E2 80 93 , which is the Unicode "EN DASH". This code received a minus sign conversion by a text editor with a cosmetology degree.

Your double quotation marks (") were probably wrong. Check to see if they really are " and not " .
