Design of Bar Code Data Acquisition System Based on Single Chip Microcomputer
AbstractWith the development of science and technology, bar code has become an commodity trading language, and the more perfect bar code technology has become an indispensable means of commodity circulation in modern and contemporary times. There are many barcode recognition devices on the market, and the general principle of barcode recognition has been clear. Now a simple, low power, simple operation barcode recognition device will be designed. The device is mainly composed of single chip computer, bar code recognition module, LCD1602 liquid crystal display and power supply. The bar code recognition module transmits the collected data information to single chip computer through serial port, and the single chip computer transmits the received data information to LCD1602 character liquid crystal display, thus realizing the display of bar code data. In the software part, Keil is used to compile and debug the program. After debugging many times, the design is finally completed.
