chrisshortys,

You can get the angle with the formula provided by aratti. However, you are going to need PBP version 6.0 for that. If you don't have v6.0, then depending on the accuracy that you want you can use a LOOKUP table.

About your second questions, do a search in this forum for ADCIN and you will find several treads that will answer your question.

ATN2 ((v-v0)/SQR((v1-v0)^2 - (v-v0) ^2))

should give you your angle (I don't remember if in degrees or in radiants)

aratti,

I believe the angle is given in binary radians, 0 to 255, that would be the equivalent to 0 to 360 degrees.

You could use a lookup table. But if you need more accuracy, you could use the Arrati's formula, and the cordic linked in his response http://www.picbasic.co.uk/forum/show...ighlight=angle, and either v2.60 in pbpl mode, or use a 16 or 32 bit square root function located here: http://www.picbasic.co.uk/forum/showpost.php?p=73685 (which is pretty much microchips TB040 located here http://ww1.microchip.com/downloads/e...tes/91040a.pdf )

By the way, version 2.60 is a very nice upgrade, and worth every penny.
