USBDemo, something to learn USB a little bit

[Darrel Taylor]

Which PIC are you using?

You probably need a modified .bas file for that chip.

If you are using a 2455, 2550 or 4550 then Steve has already provided the files. (see post 99)

You may also need to modify the PBPUSB18.LIB file if your PBP installation is not in the default c:\PBP folder. As was the case with Momboz.

Hi,

Thanks for your reply.
Errors for both 2550 and 4550;(using steve's files)
there are 2 folders in c:\PBP, one is MCSP-3.0 2ND one is PBP247,
Now different errors when iam trying to compile Steve's file from C:\PBP.
No errors from the sample folder files(pbp247)i tried with its own compiller and mpasm..

Regards,

plaese find attached image..

There may be several things going on here. Let's see if we can fix a couple of them.

First, since PBP wasn't installed in the default folder, you have to change the path to one of the files.
In your c:\mcsp\pbp247\ folder, there is a PBPUSB18.LIB file.
Open it with notepad, and change the first include line to...

&nbsp; include "c:\mcsp\pbp247\PBPPIC18.LIB"
----------

Next, edit the c:\mcsp\pbp247\18F2550.INC file with notepad.
Comment out ALL of the __CONFIG lines with a semicolan ;
----------

Then in the USBdemo program, change _FCMEN_OFF_1H to _FCMEM_OFF_1H

That will need to be changed again after the next time you upgrade MPASM.
----------

Those should fix several of the errors.
Compile it like that and let me know whats left.

Oh, and 1 more.

In Microcode studio, goto

View | Compile and Program options | Compiler tab

And select the INHX8M radio button.

Dear Darrel Taylor,

Thank you very much..compilled succesfully but few warnings..
commented like this :
ALL ; __CONFIG _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
ALL ; __CONFIG _CONFIG1H, _FOSC_HSPLL_HS_1H
ALL ; __CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
ALL ; __CONFIG _CONFIG3H, _PBADEN_OFF_3H
ALL ; __CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L

i selected only INHX8M radio button in View | Compile and Program options | Compiler tab
and disabled rest..

I'll let you know its behavior after programming the IC tonight ..

Thanks again..

Warm Regards...

Ha Ha Ha
That's funny.

Very close,
but no cigar.

should be...

   ; __CONFIG _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L 
   ; __CONFIG _CONFIG1H, _FOSC_HSPLL_HS_1H 
   ; __CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H 
   ; __CONFIG _CONFIG3H, _PBADEN_OFF_3H 
   ; __CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L

Opearation Success...

Thank you again, and i look forward to your continued support.
