PCD: Just need a sanity check!

[Robert Kinchin]

Hi, oh the problems of using a new processor lol,
Im using the PIC24FJ256GB110 in a USB enviroment and I think my problems my be hardware, but need a sanity check.

I have installed the usb_hid driver almost direct from the example just changed the pll to 3 for my 12Mhz example (using a development board while I wait for PCB's to be manufactured)

So far I have 2 problems

1. MPLAB complains that the configeration is illegal and the compiler does seem to not set the RESO bit (reserved = 1) and other reserved bits is this a problem i let MPLAB correct it.

2. I can't get the USB to enumerate, even though the code works fine when compiled for the 18F4550 so unless its the specific processor hid file i guess it hardware.

I have the USBGEN off and supply VUSB 3.3V myself and VBUS is supplied from the host usb, its only 4 wires lol

Any help please
Robert

I can't be of much help because I don't have the PIC24 compiler, but in order for other people to be able to help you: post your compiler version number.

It was hardware, development board problems, had to break out USB pins

Still would like to know about configuration problem though if any one knows of this

Incorrect set reserved configuration bits can be found also with other PIC24F chips. It's generally O.K. to let MPLAB correct them. The more interesting question is, if they could cause problems with other programmers, that don't correct them.
