FREQOUT compiler error on USB Pic

[mindthomas]

I have now got my USB Project working, and i am now working with some sound! (I needed to Comment out some lines in the 18F2550.INC file)

But now when i use FREQOUT command in my USB script i get this error:
"Warning[202] \PBP\PBPPIC18.LIB 1239: argument out of range. least significant bits used."

I don't know what it is, but i think it's somthing with a kind of config!

Generally, it means you're trying to stuff a WORD variable into a BYTE register.

Ohh, but why? The code line is this:

FREQOUT buzzer,1000,2000	'Freq=262 Hz

Open your pbppic18.lib and scroll down to line number 1239. Where you see addlw (sintable) change it to addlw low(sintable)

Bruce, What version of PBP do you have there? I just checked my latest version w/patch and find no instance of this.

Hi Dave,

I have the latest version + I keep all older versions for tech support. v2.47 is the version
I noticed the low missing in. It works even without the mod, but always returns the warning.

Open your pbppic18.lib and scroll down to line number 1239. Where you see addlw (sintable) change it to addlw low(sintable)

Thanks.. It worked, and how did you know that?

Another thing, how can i put two bytes together, because i need to select the FREQUENCE with USB, but i can only go up to 255, so how can i make so i can send a higher value?

Word, highbyte, lowbyte, byte1, byte0, and so on...
It's all in the book...

How did you know that i should do that?
Just want to know if it happends again.

If you've got MCS setup to dump out a .lst file with all the options turned on (usually fairly HUGE files), you can usually scroll thru it or search it for the phrase 'ERROR', then using a bit of deductive logic, can usually trace that back to your original problem...whether it be a problem with the typist, an include file, a macro, whatever.
