Design of LED Display Control System Based on AT89C52 Single Chip Microcomputer
This paper introduces display design process about hardware and software based on AT89C52 single chip microcomputer. We use a simple external circuit to control the display screen, which size is 32 × 192. The display screen also can display the size of the six 32 × 32 dot matrix Chinese characters by a dynamic scan mode, and can be divided into two small display screen, which can display twenty...
متن کاملLED brightness control for video display application
The technique is suggested for a kind of pulse-width-modulation LED dimming in LED video displays. The significant increase of the gray levels number and image refresh frequency can be achieved when the large number of LEDs is controlled serially. The need for a large number of grayscale levels and high refresh rate is explained. The controlling data flow and the amount of buffer memory are the...
متن کاملA Microcomputer-Based Simulator for Digital Control Systems
A microcomputer-based simulator for digital control systems is proposed. The proposed simulator is a hybrid system in which the plant is simulated by conventional method of analog computers and other parts of the system including generation of input signal is performed digitally, using a Z-80 based microcomputer. To overcome the difficulty of programming in assembly language, and at the same ti...
متن کاملDisk Generators for a Raster Display Device
A simple modification of Horn's circle drawing procedure yields a disk generator for a class of graphic devices capable of drawing rectangular areas. Another variation produces a disk a scan-line at a time allowing it to be drawn at the refresh rate of the display. The calculations involve only additions and binary shifts.
