Hi Guys, for some reason I am unable to control pic24FJ128GB110 port E. I am using c= cs=20 compiler. other pins I can turn on/off no problem. I even replaced the pic just incas= e. no=20 change after all. the other thing I was suspecting is PMP and I added a code to disable that = still=20 no change. setup_pmp(PAR_DISABLE.0); I never had pic i/o problem this is kind of strange. data sheet shows port = E is=20 digital I/O. before this I used PIC24FJ128GB108 never seen any problem with I/O any idea? thanks Andre=20 =20 --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
