Need help modifying this code

[ajhoward]

Hi there

I found this code that is similar to what I need but I need to modify it a bit and not to sure how. This code uses a interrupt caused by the closing of a switch to ground to wake from sleep, flashes a LED 10 times and then returns to sleep. I need it so the interrupt wake the PIC, which then starts a timer, which when that expires (providing the switch hasn't opened), flashes the LED until the switch is open again (which would pull the input high via a pullup resistor, which would turn off the LED and return the PIC to sleep.

Hi, its great to see you visiting our forum. Why not try Proton Compiler for FREE? Download the FREE version of Proton Compiler, Its called Amicus18 and its available from HERE Already using proton Compiler??? Get rid of these pesky messages... get LICENSED USER STATUS

Hi
I suggest you start by registering as a licensed user, and also say which version of the compiler you are using.

thanks

By ignoring a reasonable request, are you saying you are NOT a legitimate user ?
