Does this mean that the programmer needs power supplied on pin2?  This wouldn't make any sense to me as the cable I got with the programmer has no connection to pin 2.

What in-circuit programming solution did you use instead?

Further reading indicates that the usb-icp needs to be able to control the uP power supply, with a maximum of 500pF of bypass capacitance.  Is this true?  This essentially makes the in-system programming useless if the target is in a system with other devices on the same power supply and the requisite bypass caps.....

LPC9xx/LPC9xxx / usb-icp and lpc934

I'm trying to connect to a 89lpc934 via the ISP header and the Future Design USB-ICP.  I keep getting the message:

"The device signature does not match the xpected values. Accessing a device using the wrong protocol could render the device unusable."

I've installed the latest drivers and the latest version of Flash Magic.  The microcontroller has never been used before so it's in the default factory state.  Can anyone help?
