Hi to all engineers. I have a few questions 1. using picmaster 508 probe how can I enable weak pull-up, wake up on port change. it doesn't work on picmaster but actual pic works ok . 2. in my project I needed to determine logic 0 for cmos below 1,5 volts is logic 0 and above 1,5 is logic 1 I didn't want to use ADC and I didn't want to use timer to determine logic 0 so I used picmaster probe 508 the voltage I have got was about 1,5 volts when I programed the pic it didn't work when I played with pic I found that the voltage is different then what I got 3,5 volts after I looked at the data book I noticed that all inputs are TTL is this means that the pic is not static sensitive ? any help will highly appreciated Andre
