Sorry, guys, I'm resending this message since the Subject line seems to have gotten whacked the first time out. I am using the Microchip PKE Reference Design Kit (APGRD001) and I am trying to change the behavior of the S2 (Unlock) output of the decoder board. I can see in mid.asm where I can make changes based on a button push from the fob, but I can't find where to change the output based on a successful PKE result. Can anyone help? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
