Multiplication learning device design based on MCU
Abstract: This paper is about the topic titled my multiplication learning device design based on single chip microcomputer, developed a my multiplication learning device based on single chip microcomputer. The main use of technology: the basic operation of AT89C51 single chip microcomputer; LM016L LCD driver, number, character display; 4 x 4 matrix keyboard scanning input; Interrupt timing scan data; Buzzer, etc. The final product to complete the following functions: user-defined input my multiplication; Randomly generated a my multiplication; Positive sequence shows my multiplication; The reverse shows my multiplication; My multiplication tests.
Demonstrated in the paper, firstly introduces the design scheme, pided into the design of the hardware design and software design of two parts. Then introduces the hardware design of the specific module, the connection between the modules. Then introduces the detailed content of software modules, including the function of the module, flow chart and detailed code implementation. Finally is a combination of hardware and software debugging, to solve the problem in the debugging process, continuously improve the content, the final conclusion. The end of the paper is the reference, the main part of the source code.
