Compiler Warning Messages
Unsigned variables are never less than 0. This warning indicates an attempt to check to see if
an unsigned variable is negative. For example the following will not work as intended:
int i;
for(i=10; i>=0; i--)
Variable assignment never used.
Variable of this data type is never greater than this constant
A variable is being compared to a constant. The maximum value of the variable could never be
larger than the constant. For example the following could never be true:
int x;
// 8 bits, 0-255
if ( x>300)
Variable never used
A variable has been declared and never referenced in the code.
Variable used before assignment is made.
