pic16c745

I need to know how I obtain the windows drivers for
the pic ? It's one thing to program a pic, it's a
whole other thing to program the windows driver model?

 

The "Windows driver model" is confusing. Do you mean the Windows-based assembler/compiler/programmer?

If so, I use PicStart Plus development system from Microchip. MPLAB is easy to use once you figure out the menus. www.microchip.com
.. Select "development systems", then "programmers".

There are others available through Digi-Key also. www.digikey.com

Nope. The PIC16C745 implements a low speed USB interface suitable for HID
devices such as mice and keyboards.

Missed point. My understanding is that the standard HID drivers work for the
PIC when implementing the code in the datasheet. Read it carefully.

its my understanding that those drivers are for the programmer hareware
and not for your use after the fact..
they have USB programmers.

 

WHAT ????

Are you talking about "programming the PIC with a USB" device or
Are you talking being a Winxx program using USB devices ???

If the latter, I too would be interested how to use Winxx development
tools to talk to USB devices.

Thanks for any links.

What I mean is not how do I program the PIC itself, but
rather where do I get the windows 2000 drivers that will
recognise my device when I plug it to the usb. Just to
explain further, I have got pickit1 which interfaces to
windows 2000 exactly like this, it has a PIC16C745 on it.
When I installed pickit1 I had a cdrom which installed
the drivers for the board on windows 2000. These are the
drivers which are prompted for as one plugs in a usb
device. I couldn't find any mention of this in the
documentation of this PIC.

 

WHAT ????

if this is what you need then you have to get the ddk from
microsoft, it's about 100 $. You also need a bunch of books,
and about 2 years of completely free time. Now you see, this
is what I want to avoid, the drivers must be already there
for this device otherweise it simply doesn't make sense,
microchip surely doesn't expect pic programmers to be ddk
programmers.

 

Elektor had a project using this chip a few months ago (November,
December?) - it may be worth checking out.

IIRC, depending on how the usb is implemented on the 16c745, windows
can use it as a standard Human Interface Device with its built-in
drivers. No custom driver required if you do it like this.

you need to get the DDK from MS, you most likely need to
create a HID driver (human interface Device), the DDK is a
device driver Kit and you will need VC++ (visual C++) from
MS also. there are loads of examples on the CD for making
USB device drivers., the DDK was free the last time i looked
you will need to pay shipping and handling.
you Pic will need to responed to an ID request from the OS so that
windows can locate the driver it needs to use for your device..
if you go to the Intels Web site you can get the required USB
signitures that are expected so that this device can work 0n any
platform as long as the drivers are there.
the protocol for the coding it not that hard, its alittle different
than RS-232 but you will do fine.., it uses simpe CRC etc..
