| Abstract: | A linear speed measuring system, which has phonetic and animated output equipment, has been developed. The system's controlling CPU is a AT89C55 microcomputer, and it adopts quick reaction infrared photo triode as the input signal. The phonetic chip ISD1420 has been carefully researched, and the chip's working mode and basic circuit diagram are both described in the paper. Based on the study of SED1335 liquid crystal display device, the interface circuit between AT89C55 and SED1335 are introduced. |
