CYPRESS SEMICONDUCTOR CORPORATION Internal Correspondence Date: 20/12/2008 WW: 0852 To: Kumar Golla (UKG) Author: Adithya Reddy G (UKGTMP7) Author File#: 2 Subject: PSoC Application based on Persistence of vision CC: SONI, LKH, GMYR,AOG EXECUTIVE SUMMARY: This memo introduces the PSoC application that features display with limited number of LED, based on persistence of vision. OVERVIEW: Rotation of single LED with high speed in circular motion gives the appearance of complete circle due to the persistence of vision. This idea can be extended to rotate a line of 5 LEDs perpendicular to its length and thus create a display of letters or numbers. These LEDs should be made to blink with specific timing depending upon the display needed. A line of LEDs can be mounted on a table fan for rotation. If we could number the 5 LEDs as LED[4:0].
