Here is the patch to make pk2-1.34 working with the original
V1.01 firmware which has the bug of using the same configuration
index value for 2 configurations.

1) change the following line:
const static int pickit_configuration = 2;	// 1: HID; 2: vendor specific
to
const static int pickit_configuration = 1;	// 1: HID; 2: vendor specific

2) Add the following code before setting the configuration, i.e. line
244 "(if (usb_set_configuration(d, pickit_configuration))" for Linux.

			// The following is required for V1.01 firmware
			#ifndef WIN32
				{
				int retval;
				char dname[32] = {0};
				retval = usb_get_driver_np(d, 0, dname, 31);
				if( retval == 0 && strcmp(dname, "usbhid") == 0 )
					{
					usb_detach_kernel_driver_np(d, 0);
				        }
				}
				#endif
                          //end of added codes
				if (usb_set_configuration(d, pickit_configuration))
						bad("Error setting USB configuration.\n");

The function of the added codes is to detach the kernel usbhid driver
which claims the PICkit 1 HID configuration.

The added codes are also okay with firmware version 1.03 which has the
configuration index bug-fix.

The next revision of PICkit 2 firmware will support 
the 18F USB chips as well quite some popular 16F and
18F chips. It is scheduled to be released by end of 
this year.

Take note that the chip supported is from Microchip.
Mark's Python based pyk already supports 
16F73/74/76/77, 16F676 and 16F737/747/767/777
with the first revision firmware. Pyk supports
most of the chips supported by Microchip. The
latest pyk also supports the bootloader function.

With the next firmware, PICkit 2 will be truly a
hobbyists' programmer since it will work under Linux 
and Windows and supports most popular under-40pin 
(read: DIP version available) modern Flash PICs.

Together with Wisp628 (with xwisp2 1.8.1), I think
these two programmers are worth a try if you want to
try a new PIC programmers. Wisp628 is easier to be
built by oneself. PICkit 2 (US$35+shipment) is good if 
you want to buy a ready-made programmer.

Can it do a pic18f2550?

By the way, the latest pyk/pk2 package works under Windows 
using libusb-win32 device driver besides Linux.

To run pyk/pk2 under Windows, I have written a mini-howto. 
I also put up the source+Win32 binary packages at the 
following thread:
http://groups.google.com/group/pickit-devel/
Thread: "Mini-howto: how to run pk2 and pyk under Windows".

Or you can directly use the following link but be careful
of URL truncation.
http://groups.google.com/group/pickit-devel/browse_thread/thread/e4ff7529a1c
dd68d/f3812040c5426c0e?hl=en#f3812040c5426c0e

If you have problems specifically related to Windows, please
do not bug Mark and Jeff since they normally use Linux. You
can post to the pickit-devel group and I will try to help
you there. 

Anyway, the Windows support is just a byproduct and the Linux 
support is more interesting since Microchip will take care of 
PICKit 2 Windows.

PICkit 2 V1.10 has been released. Please refer to microchip website
(http://ww.microchip.com/PICkit2) for detail. Take note that the Linux
application pk2 and pyk does not support 18F yet. The V1.10 firmware
itself may support more chips than Microchip's PC application. For
example, it is reported that pk2-1.34 already supports 16F627/16F871
under Mac OS X.

Xiaofan

18F support is halfway there in the latest version of pyk.  Well, it's
completely there, but it doesn't work yet!
