To busy to read right now but I wouldn't put a comment line between the condition of an "if" and the opening {, it could crash things.

Like you've done at many locations.
example:

if(&myflag == 0)
// look if fence is closed If closed:
{
//rest of the code
}

should be
either

// look if fence is closed If closed:
if(&myflag == 0)
{
//rest of the code
}

or

if(&myflag == 0)
{
// look if fence is closed If closed:
//rest of the code
}
