Abstract
This system based on the USB2.0 interface chip CYTC68013A, uses 74HC138 and 74HC595 to form ranks control cir- cuit to drive the 16x64 LED display. This system displays graphic information at high speed and dynamically. This paper introduces the design of hardware circuit, firmware program and application program. The experiment results shaw that by calling different library files,the system can dynamically display Chinese characters in HZK16, characters in ASC16 and the size of custom picture.关键词
