USB Interfacing with PIC 18F452
PostPosted: Mon Mar 19, 2012 3:01 am     Reply with quote

I have read many forum i found that there is no compatibility of USB with PIC 18F452
but when i see example program there is some awesome thing or this my mis_interpretation that PIC 18f452 support USB protocol but there is no D+ & D- PIN in PIC 18F452
Code:

/////////////////////////////////////////////////////////////////////////
////                                                                 ////
////                        ex_usb_serial.c                          ////
////                                                                 ////
#if __USB_PIC_PERIF__
 #include <18F4550.h>
 #use delay(clock=48000000)
#else //use the National USBN960x peripheral
 #include <18F452.h>
 #use delay(clock=20000000)
#endif   //endif check to see which peripheral to use

Note the line:
"//use the National USBN960x peripheral"

This is the 452, talking to USB, _with a separate interface chip_.

Also, remove the code you have posted, since you are in breach of the copyright:

"No other use, reproduction or distribution is permitted without written permission."

You can simply refer _to _ the library by name here, since everybody already has the compiler files if they own the compiler. Posting the files though is _illegal_.
