Hello,

What size have you declared for the global array?  To return the array[8] element, the array size would need to be 9, or more.

Hello electronicfan,

Assuming that you decare an array to contain eight elements,

unsigned char array[8];

The first element of the array will be array[0] and the last element will be array[7].  The element array[8] does not exist.
