FREQOUT compiler error on USB Pic

[Bruce]

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

[Dave]

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

Dave Purola,

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.

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...

Ya, but when i need to send it over USB?

Same thing applies going either sending or receiving...

variableword var word
variable_highbyte var byte
variable_lowbyte var byte

variableword = (variable_highbyte * 256) + variable_lowbyte
variable_lowbyte = variableword.lowbyte
variable_highbyte = variableword.highbyte

variableword = (variable_highbyte * 256) + variable_lowbyte
variable_lowbyte = variableword.lowbyte
variable_highbyte = variableword.highbyte

In english please
But look at this:

USBBufferSizeMax   con 8  ' maximum buffer size
USBBufferSizeTX    con 8  ' input 
USBBufferSizeRX    con 8  ' output

' the USB buffer...
USBBufferIn        Var Byte[USBBufferSizeMax] 
USBBufferOut        Var Byte[USBBufferSizeMax]
USBBufferCount   Var Byte 

   USBBufferCount = USBBufferSizeTX              ' TX buffer size
   USBService                                    ' keep connection alive
   USBOut 1, USBBufferOut, USBBufferCount, DoOutBuf ' if bus available, transmit data

[skimask]

In english please

That's perfect english...shows how to define a word and a couple of bytes, and how to split them up and join them back together.

But look at this:

What about it?

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.

The warning message tells you where the problem is. Warning[202] \PBP\PBPPIC18.LIB 1239

I looked in the library at the line # indicated by the warning message. In v2.50a there was no problem. In v2.47 this was missing, so it's a simple fix to get rid of the warning.

It also helps if you know assembler...;o]

Ya know, I never made the correlation between the 'PBPPIC18.LIB' and the '1239' in the error messages. I always did it the hard way described above.
Thanks for the tidbit...

Ohh, it's because i have PBP 2.46!

[Bruce]

It may go back a few versions, but I didn't check back any farther than 2.47.

$25 for the upgrade...

[mindthomas]

$25 for the upgrade...

To what, 2.50?
