PIC18F14K50 USB Not Working
Okay, it looks like I'm stuck with the 18F4550 for my USB projects. Nothing else seems to work for me. I'm trying to just compile this program with the Include "descript.bas", but it doesn't work. This descript file works just fine with the 18F4550. I checked the USB_DEV.ASM and USB_HID.ASM files, but I don't know what the problem is. It might be an easy fix, but this assembler language is not my best friend. Any help is appreciated. Thanks, Robert

Define OSC 16
OSCCON = %11110111
#CONFIG
CONFIG CPUDIV = NOCLKDIV ; No CPU System Clock divide
CONFIG USBDIV = OFF ; USB clock comes directly from the OSC1/OSC2 oscillator block; no divide

Re: PIC18F14K50 USB Not Working
Does that short piece of code (with different CONFIG of course) really compile for the 18F4550 but not for 18F14K50?
There really isn't much actual code there is it?
I see no USBINIT or anything so it might be that the USB libraries aren't included by PBP during compile time and therefor the variables that the assembler is looking for isn't being declared.

What is "Include "descript.bas"?
Re: PIC18F14K50 USB Not Working
maybe he meant
Include "hid_desc.bas" ?

Yes, it compiles for the 18F4550 even without the config lines.

Hmm, it works with the "hid_desc.bas" include. The descript.bas file is part of a HidMaker package that I bought before. Apparently, this descript file was made only for the 18F4550. Unfortunately, HidMaker went out of business. His owner Dr. Bob is not even responding to the emails. It is a shame to see a great program like HidMaker to close.
Re: PIC18F14K50 USB Not Working
Maybe the syntax of the descript file is different than the one expected?
Anyway it is a pity to see that company shutdown.
People are getting old, retired or even die...

Also, PBP is getting less popular everyday. I'm going to have to dust off my C language skills again because I think that's what people are using the most today to program the PICs.

I hate to admit it but yeah, that is very true. We all should do that.
But I also hate C...

I'm not a big fan of C either.
