SHDEFCIRCLE (Statement)

Function

Sets the condition for searching a circle.

Format

SHDEFCIRCLE <Clearance>, <Width>

Explanation

<Clearance> Designates the clearance between pads for the circle search (1

to 10).

<Width> Designates the pad width for the circle search (1 to 10).

A circle is detected with an average brightness of 2 pads,

as shown in the left figure.

In other words, if SHCIRCLE is 0, a circle is detected when

the difference between the average brightness of A and

that of B is larger than the difference in SHDEFCIRCLE.

You can adjust the pad clearance and width with

SHDEFCIRCLE.

Note (1): This instruction is a temporary setting, so the initial value is

not permanently changed.

Note (2) : For this instruction, a µ

µµ

µVision board (option) is required.

Note (3) :If a large clearance is set, it is only slightly affected by

disturbances in detection but detection accuracy lowers.

Note (4) : The initial values set at the factory prior to shipping are as

follows: clearance = 1 and width = 3
