Published:2011/4/18 1:52:00 Author:Rebekka | Keyword: Drawing light pen
The circuit uses the way of short cut off input to avoid input data confusion. So that the ability of drawing light pen on the display will be improved. The resistance of R1 is decided by light pen. For H-35 light pen of Texas lnstrumens, R1 is 1MΩ. Monostable NO.1 produces 200ns pulse that is rate constant so that l or 0 stored in the cathode-ray oscilloscope graphical interface can be stored in 2102 memory. (View)
