+pic18f452 hang problem
Hi all,
I am working on a project on which i have to send some information via RF. my system works fine on a PCB i made as a general purpose. my second board works fine but when i enable GIE it hangs. if i do not enable interrupt it is fine. (does not hang) extra things i have added in this board are Ferrite beads on Key Pad inputs and to RF module.
one 5V DC relay is also added. i use diode for protection (freewheeling) i am in a fix why my system does not work when i enable interrupts.
my complete system was working on a PCB which is small in size.
does orientation of PIC cause an interrupt to occur, or Hang my system, remember i have not interfaced RF module to my system.
Please Advice.......
