PBP v2.50a Vs 2.60 and USB compile errors

[trout59]

I'm trying to recompile on PBP v2.60 a program that was originally compiled under PBP v2.50a, it uses USB on a 18F4550, I get the following Assembler errors

Error[113] c:\pbp\pbpic18.lib 715:Symbol not previously defined (USBDeviceInit)

I get this twice and then similar for USBDeviceTasks and PutUSB

The original code had usb18.asm, usb18.inc, usb18mem.asm and usbdesc.asm with the pbp source files (I think these are the same as in the USB18OLD directory under C:\pbp) I have read the USB.txt in the USB18 directory and have tried adding usb_dev.asm, usb_dev.inc etc to the source directory but still get same errors.

I'm also a bit new to USB so I maybe missing something simple........

Due to changes made to MPLAB 8.20 and above, the old USB files would no longer compile and new ones had to be written by meLabs.

Different USB files need to be used in the project now, and a new descriptor must be generated. EasyHID descriptor files no longer work.

For HID, see this post ...

Hi, Darrel

I tried to update my "USBdemo" as stated in the first link you provide ...

BUT got:

C:\PROGRAM FILES\MICROCHIP\MPLAB IDE\PROJETS\USBDEMODESC.BAS ERROR Line 7: Bad BANK number.Halting build on first failure as requested.
BUILD FAILED: Thu Mar 18 09:15:16 2010

and line 7 is :

USBReservedMemory Var Byte[USBMEMORYSIZE] USBMEMORYADDRESS	' Reserve memory used by USB assembler code

that sends us to

USBMEMORYSIZE	Con	256	' USB RAM size in bytes

and

.
.

        include "PBPPIC18.RAM"
USBMEMORYADDRESS Con	$400	' USB RAM starts here

...

resulting in that I do not see what's wrong ...

Dong, Dong, Dong, Dong ....

PS: PBP2.60 + MPLAB 8.46

[Darrel Taylor]

Which all seems good for an 18F2455/2550/4455/4550 series.

Some of the newer chips use $200 for the USBMEMORYADDRESS.
But that's taken care of automatically.

Which PIC are you using?

[Acetronics2]

I use a 4550, the one I used for the original Demo ...

[Darrel Taylor]

Is that the only error you get?
I suspect there may be another error before that one?
