Great cow basic does not have a good help file to get started
Me personally I'm saving up for
www.mikroe.com using pascal as I'm famila with the language with Pentium processor.
Its just the IO I'm learning to manage
I'm waiting for one of those new pic18f2250 USB programmers
I wish they would learn the old trick
write a program to load new programs down by USB
then the programmer can be up dated from its own USB port
I thick you are best to pay for software that you first ask for usb support
before paying and knowing what you pay for before doing it
you need to read about USB2 before you go their too
Ask Microsoft etc

I think my question is still not clear. I want to use GCB to control the USB hardware that is built into the 18F2250 (and other parts) so that my GCB program can communicate via USB with a PC. I don't wish to use an external hardware chip (such as the FTDI chip family) to do this; I want to use the PIC's internal USB system.
As to USB bootloaders, there are a number of them out there for free. For instance, Microchip has a USB bootloader that you can program into a USB-capable part. That's not what I'm looking for.

only pic18f2250 and its pic18f mates support USB because serrial is much slower and needs less hardwere.
but these pic18f's are programed by serial port still like the rest
I'm waiting for a USB version of PicAxe firmwere to come out on a pic18f2250
that you can make a firmwere file to load directly above the first one
with usb
That would be ideal for a USB pic programmer that can be up loaded with updated firm were as it comes out.
But the only way this would happen is taking my idea and advertizing it.
Hopefully it would be the one programmer standard that eventually programs all manufatures microcontroler chips.
a bit like PC compatable when it came out.

I don't think "cow basic has not gone where you wish to go" is a constructive answer. The assembly USB-handler code to do this is freely available and numerous creative folks have rolled it into code written in numerous other languages. It seems to me that it's mostly a matter of compiling the open-source assembly handlers in with the GCB code, and then calling these routines from GCB.
"It can't be done" is an unacceptable answer. What I'm looking for is how to do it, even if it's difficult, not why it can't be done.

I have my eyes on mikroPascal if I need to do something like that
Have you gone on to the microchip dicusstion group
they have agroup just on USB and 5 year plus devalopers are thier
They realy talk about stuff when it comes to USB
Just an idea
Best regards

A USB solution for GCBasic is also an issue for me. Would be happy if this could be realized in the near future. Can you inform me were to download an assmbler code and how to wrap it in GCBasic?
USB programmer with USB port is the one from Microchip PICKIT2 or any of that many clones outside there. I have built a fully compatible on (without eeproms) and it works very well. It uses th 18F2550.
Thanks

I asked a simple question and the reply was to only use code they created

That metailty is very stupid to do any project
buy the Pacal for microchips yet
its quite advanced
when you create the Delphi code to comunicate to the chip
Make a *.dll that is loaded up at start up and Do not use stand C++ procedure but use Delphi procedures
Then c++ cannot read the dll and .net cannot ether
as long as its installed before a .net program is exicuted
Then you do not need .net with your version of Delphi
Make your *.dll get all your programs resurses
one day Delphi programmers will make thier own .net eqiverlant in Delphi

Has anyone done any USB development using the PIC's internal USB system?
Joe
USB uses a lot more start up communication to get going
They are using the pic18f2250 for this
please read

The question was "is anyone using GCB to program these parts"

again Cow basic has not gone where you wish to go
you will have to pay through the nose for that
or learn from assembly code

I have used one example with uart over usb. What type of usb application do you effectivly need ?
