Problem with MCLEAR and output value
PostPosted: Tue Aug 10, 2010 4:24 am     Reply with quote
I am trying to do a keylock using IRS.

Guys, can someone teach me how to make an output pin HIGH when the mclear of a pic is grounded?

Coz, when the mclear is high, the output is high, which is great but when i mclear the pic , the output goes to low, but i want it to remain high. So can anyone help me out?

When you put a low on mclear, it resets the pic.

All I/O pins will float, so you will need to tie the specific pin you want high to vcc via a suitable value resistor.

When mclear is low, the PIC is not running, so how do you expect software to be able to control the pin state.
