With the continuous improvement of people's quality of life, the increasingly high performance requirements of vending machines. Vending machines The main function of the form of man-machine dialogue vending this process.The designed a produced by Intel 80C51 microcontroller as the core vending machines, and emphasizes the detailed description of the overall system design of the vending machines, hardware options, software and the use of methods and techniques. As 80C51 CPU processing unit connected to the various functional modules; 4 * 4 matrix keyboard as an input control module of goods, the choice of the type and number of input and analog currency; LCD1602 LCD as the display module to display the current state of shopping as well as currency state; LED display indicates the current selection of goods and shipment status...
