PSET/de

= (**COPIED FROM ENGLISH PAGE**) === Action

Sets or resets a single pixel.

 

 

Syntax

PSET X , Y, value

 

 

Remarks

X	The X location of the pixel. In range from 0-239.
Y	The Y location of the pixel. In range from 0-63.
value	The value for the pixel. 0 will clear the pixel. 1 Will set the pixel.

 

The PSET is handy to create a simple data logger or oscilloscope.
