PIC18F4450 and USB
PostPosted: Tue Dec 18, 2007 5:58 pm     Reply with quote
I can compile the CCS example ex_usb_kbmouse2.c out of the box without problem. When I make the following change:

replace

#include <18F4550.h>

with

#include <18F4450.h>

I get
Code:

Clean: Deleting intermediary and output files.
Clean: Deleted file "ex_usb_kbmouse2.ERR".
Clean Warning: File "C:\Projects\bigkeys\Code\ex_usb_kbmouse2.o" doesn't exist.
Clean: Done.
Executing: "C:\Program Files\PICC18\Ccsc.exe" "ex_usb_kbmouse2.c" +FH +DF +LN +T -A +M +Z +Y=9 +EA

This doesn't seem right - there might be more changes required to make it work, but it should at least compiler - Or shouldn't it? Any help appreciated.

I tested it with vs. 4.064, and it doesn't compile. It gives the same
errors. CCS has some #if and #elif statements in pic18_usb.c
to configure the code for the 18F4450. Apparently, it needs to be
fixed for the Ex_usb_kbmouse2.c example. I suggest that you
contact CCS Tech support and ask them about it.
