Hi

Z just got commented out by accident... My Bad.. It back now and was anyway !

Sorry again my misunderstanding if the ATN result is radians 0 to 255 the equation as I remember is:-

Degree = radians x 180 over PI

You see my confusion ?

from the pbp manual

ATN returns the 8-bit arctangent of 2 two's-complement 8-bit values. If a byte is
greater than 127 (high bit set), it is treated as a negative value. The arctangent
returned is in binary radians, 0 to 255, representing a range of 0 to 359 degrees.
