ibutton question

if your putting the pic into a sleep mode for what ever reason you guess you could connect the input signal to an input that can be programmed to fire off an Interrupt. the start of this pulse should force the IRQ code to jump rite to the reading loop etc... in other words, either program the input line to trig an IRQ when it goes into sleep mode and then shut it off on the first trigger or use a different input and tie them together. etc..

Hello all

Just started using the Dallas/Maxim DS1990A with a DS9092 Touch Probe using a PIC16F505 as the Master. Everything works fine if the PIC polls the probe and when the Touch Memory is present, the serial number is successfully read. My question is...

Is there anyway I can 'wake-up' the PIC from Sleep when I place the DS1990 in the DS9092? In other words, can I get the DS1990A to generate an interrupt?

Cheers, Simon
